Password Security using  Group Theory Part  1 of 5
Benjamin Fine (Fairfield University). Title: Password Security Using Combinatorial Group Theory Abstract. Joint with: Gilbert Baumslag and Doug Troeger. Over the past decade and a half there has been a concerted effort to apply combinatorial group theoretic methods to cryptographic protocols. In this talk we briefly explain how group theoretic techniques are applied to cryptology and then consider a method to apply group theoretic techniques to password security. Challenge response methods are increasingly used to enhance password security. In particular we present a very secure method for challenge response password verification using combinatorial group theory. This method, which relies on the group randomizer system, a subset of the MAGNUS computer algebra system, handles most of the present problems with challenge response systems. Theoretical security is based on several results in asymptotic group theory and these will be explained as well.

Navy Operations Specialists: "Horizons Unlimited" 1975 United States Navy Training Film
more at http://quickfound.net/ "This 1975 Navy training film introduced sailors to the duties of the Operations Specialist (OS) rating." US Navy training film MN-11502 Public domain film from the US Navy, slightly cropped to remove uneven edges, with the aspect ratio corrected, and mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). http://creativecommons.org/licenses/by-sa/3.0/ http://en.wikipedia.org/wiki/Operations_Specialist_(United_States_Navy) Operations Specialist (abbreviated as OS) is a United States Navy occupational rating. It is a sea duty-intensive rating, with most of its billets located afloat and assigned to warships, primarily guided missile cruisers, guided missile destroyers and frigates, as well as aircraft carriers, amphibious assault ships and tactical air control squadrons... Brief history The rating started from the Radarman (RD) rating. When the Radarman rating was split up into OS, Electronics Technician (ET), and Electronic Warfare Technician (EW) ratings, the original RD rating badge continued to be used by the Operations Specialist. It symbolizes the radar scope (circle portion of symbol) the pipology (radar pip displays on radar scopes) showing the ability to read various sized radar targets at various distances (the two spikes in the line drawn across the scope), and the arrow represents the ability to detect the azimuth or direction of the target. Description Operations Specialists aboard U.S. Navy combat vessels work in the Combat Information Center (CIC) or Combat Direction Center (CDC), aka: Combat, the tactical "nerve center" of the ship. Using a wide variety of assets available to them, they are responsible for the organized collection, processing, display, competent evaluation and rapid dissemination of pertinent tactical combat information to command and control stations, upon which sound tactical decisions may be made. Beginning training for Operation Specialist was centrally located in Damneck, Virginia. Intermediate and Advanced training in locations like California, Virginia, and various locations throughout the United States Navy. They maintain Combat Information Center (CIC) displays of strategic and tactical information, including various plotting boards and tables depicting position and movement of submarines, ships and aircraft as well as tote boards containing data relevant to the tactical picture. They operate surveillance, tracking and height-finding radars, Identification Friend or Foe (IFF) equipment, HF, VHF and UHF radios, Tactical Data Link (TADIL-A/Link 11, TADIL-J/Link 16, etc.) systems and displays, and computerized consoles and peripheral equipment that allows them interface with the Aegis Combat System. They operate encrypted and non-encrypted long and short range radiotelephone equipment as well as intraship communication systems. With specialized training, they also may serve as combat air controllers for helicopters, anti-submarine patrol aircraft, and jet strike fighter aircraft in Anti-Submarine Tactical Controller (ASTAC), Sea Combat Air Controller (SCAC), and Air Intercept Controller (AIC) roles. They also serve as watch supervisors, watch officers, and section leaders underway and in port aboard ship and at commands ashore. Operations Specialists assist in shipboard navigation through plotting and monitoring the ship's position using satellite and other electronic navigation resources, as well as fixing the ship's position near landfall using radar imaging. They interpret and evaluate presentations and tactical situations and make recommendations to the Commanding Officer (CO), CIC Watch Officer (CICWO), Tactical Action Officer (TAO), Officer Of The Deck (OOD), or any of their commissioned officer surrogates during various watch or combat/general quarters conditions... A minimum of a Secret security clearance is required for this rating, with more senior personnel holding a Top Secret clearance. Operations Specialists provide to their shipboard or shore-based command a wide range of technical information and assistance related to Anti-Surface Warfare, Anti-Air Warfare, Anti-Submarine Warfare, Amphibious Warfare, Mine Warfare, Naval Gunfire Support, Search and Rescue operations, radar and dead reckoning navigation, overt intelligence gathering and transmittal, and other matters pertaining to the Operations Specialist's area. They also have a working knowledge of protocols and procedures in Electronic Warfare, though this area is normally covered by its own occupational rating, such as Cryptologic Technician (CT) aboard ship or ashore, or Naval Aircrewman (AW) aboard specific naval electronic warfare and reconnaissance aircraft...

Blockstream's Technology Could Make Bitcoin Transactions Unknown
Steemit, the CEO of blockchain discipline and cryptological systems processing fresh Blockstream, freshly introduced a discipline called "Confidential Transactions" as a split of the staring maker Elements blockchain platform. Though Private Transactions (PT) was one of the more technologies featured on the Elements blockchain construction, the group and industry took power in the PT subject which could in theory anonymize bitcoin transactions and move inflated concealment for users. As of modern, the semipublic bitcoin blockchain is transparent and outside to anyone within the bitcoin blockchain scheme. By utilizing the transparent and redistributed journal of the bitcoin blockchain, anyone can looking the balances of human accounts on blockchain explorers and move the trails of payments. Withal, Secret Transactions decimate the concept of anyone surveilling on the turn of bitcoin or money stored in bitcoin wallets and accounts due to its noesis to encrypt the total in a bitcoin dealing. In an interview, Support explained that Private Transactions is a engineering which can be adopted by else cryptocurrencies, blockchain networks and straight traditional database or accounting platforms. " Secret Transactions (ST) subject is something that remaining subject companies in the ecosystem feature adopted - I reckon we started a tendency. It's actually attainable for people to use a Confidential Transactions aggregation and mix it into a database, flush a stereotyped register system. There are lots of fermentable uses for it. At stock it's a profession for having an encrypted journal that you can ensure the consistency of without necessarily existence healthy see all the transactions' values," said Gage. There exists several privacy-focused unknown cryptocurrencies such as Zcash and Monero that utilize technologies such as ZKsnarks and RingCT, developed by Bitcoin Set developer Greg Physicist. Monero is unequalled in the perceive that it took Maxwell's RingCT field to other take by implementing new technologies specified as halo signatures, hiding addresses, and Kovri. Zcash relies on a cryptological engineering called ZKsnarks and the Zcash development team was praised by the community for proper the freshman group to use ZKsnarks for a large-scale cryptocurrency. Yet, both Aft and Justice Mow, the supervisor strategy functionary at Blockstream, explained that the feat of ZKsnarks by Zcash is lower economical in comparison to Secret Transactions as it is much pricey computationally for CPUs to run. "I conceive 90% of the transactions are not using the shielded transactions boast, they are honorable unprotected and inbred transactions because in implementation it was too pricey," explained Bet. Now, who previously criticized the trustworthy equipment of Zcash which required a forgather of heptad developers to train keys that can be old against the Zcash meshwork when unclothed, also criticized the shielded transaction engineering. "Zcash is an nonstandard profession compared to CT. It's supported on a trusty set-up; so you acquire to cartel that when they did the falsehood, everyone was playacting frankly and no one was compromised. Also, due to the instance it takes to communicate a shielded transaction, real few transactions are really backstage. ➠Make Donations, Be Our Partner, Encourage Our Growth: ●BTC Address: 1EmeoaRBMh6b88pbhWkXzZqptkZG15dWuy ●ETH Address: 0xd18203c7a7ac80dbbb6d6f0ee62a4d37626e815a

Time to RANGER UP!!!!!
Ontology (ONT) Leads Market Rallies - Correction Coming Up?
It’s https://www.investdiva.com/ ‘s Kiana Danial with News BTC and here is your cryptocurrency update. We saw a relative rebound across the crypto market on Tuesday, but one coin took the surge to another level. I’m talking about Ontology, ranking 21st by market cap, which saw over 29% gains. Ontology was launched by a Chinese company, OnChain, last year. It’s been focusing on a wide range of projects, providing new high-performance public ledgers and smart contract systems. Some market participants believe Ontology is a giant step toward removing barriers between the blockchain and business industries because it allows businesses without previous knowledge of distributed networks use the blockchain technology. According to their white paper, Some of Ontology’s scenarios include a Multi-Source Identity System for people, a Multi-Source Identity System for Objects, and a Distributed Data Exchange. Ontology supports collaboration among chain networks using all its different protocol groups. Ontology`s token, ONT, tested the $5.00 barrier on Tuesday according to coinmarketcap. It also rallied against Bitcoin, as ONT/BTC uptrend continues on the daily chart. You need to keep in mind that Ontology’s price action is very young, and the markets could still be testing it out. Therefore, we could see a correction sooner or later. Thanks for watching, invest responsibly, and I’ll see you with more updates tomorrow.

Distributed Ground Systems building enhances Airmen capabilties
The distributed ground systems building on Langley Air Force Base is a major systems upgrade for Air Force Intelligence. The newly built 120,000 square foot building is home to the 497th Intelligence, Surveillance, and Reconnaissance Group and houses some of the most sophisticated surveillance and reconnaissance equipment in the world, giving the Airmen using it greater capabilities. " We quadrupled our ops floor space and now have the space to conduct two simultaneous high altitude missions and four medium altitude missions," said Col. Mark Cooter " it provides more cohesion, everyone is closer together to support one another for operations, " said Tech Sgt. Gregory Artis The new building has over 1,000 miles of cable and roughly 24,000 fiber connections within its walls, which allows information coming in from U-2, Predator, Reaper, and Global Hawk to be analyzed and disseminated quickly, but the building also offers another advantage to the airmen who work in it. Prior to moving in, the Group operated out of a six building complex, now they all reside under one roof. "Instead of running a document or info across campus or across three buildings, now it goes from one room, it may go across the hall, furthest it is going to go is from the second floor north wing to the first floor south wing," said Master Sgt. Joaquin Raya Being in one central location allows for information to get to the war fighters faster, allowing for a greater probability of mission success. We now have the capacity to do more for the commander of AFCENT and the other component NAF's out there in the world today. For U.S. Army Corps of Engineers employees who oversaw the construction of the new facility the knowledge and capabilities of the Airmen who utilize the systems housed within is amazing. "What the building houses is phenomenal and the people coming up it's just amazing what they know," said Pat Devereux From Langley Air Force Base, Patrick Bloodgood
Symmetric Key and Public Key Encryption
Modern day encryption is performed in two different ways. Check out http://YouTube.com/ITFreeTraining or http://itfreetraining.com for more of our always free training videos. Using the same key or using a pair of keys called the public and private keys. This video looks at how these systems work and how they can be used together to perform encryption. Download the PDF handout http://itfreetraining.com/Handouts/Ce... Encryption Types Encryption is the process of scrambling data so it cannot be read without a decryption key. Encryption prevents data being read by a 3rd party if it is intercepted by a 3rd party. The two encryption methods that are used today are symmetric and public key encryption. Symmetric Key Symmetric key encryption uses the same key to encrypt data as decrypt data. This is generally quite fast when compared with public key encryption. In order to protect the data, the key needs to be secured. If a 3rd party was able to gain access to the key, they could decrypt any data that was encrypt with that data. For this reason, a secure channel is required to transfer the key if you need to transfer data between two points. For example, if you encrypted data on a CD and mail it to another party, the key must also be transferred to the second party so that they can decrypt the data. This is often done using e-mail or the telephone. In a lot of cases, sending the data using one method and the key using another method is enough to protect the data as an attacker would need to get both in order to decrypt the data. Public Key Encryption This method of encryption uses two keys. One key is used to encrypt data and the other key is used to decrypt data. The advantage of this is that the public key can be downloaded by anyone. Anyone with the public key can encrypt data that can only be decrypted using a private key. This means the public key does not need to be secured. The private key does need to be keep in a safe place. The advantage of using such a system is the private key is not required by the other party to perform encryption. Since the private key does not need to be transferred to the second party there is no risk of the private key being intercepted by a 3rd party. Public Key encryption is slower when compared with symmetric key so it is not always suitable for every application. The math used is complex but to put it simply it uses the modulus or remainder operator. For example, if you wanted to solve X mod 5 = 2, the possible solutions would be 2, 7, 12 and so on. The private key provides additional information which allows the problem to be solved easily. The math is more complex and uses much larger numbers than this but basically public and private key encryption rely on the modulus operator to work. Combing The Two There are two reasons you want to combine the two. The first is that often communication will be broken into two steps. Key exchange and data exchange. For key exchange, to protect the key used in data exchange it is often encrypted using public key encryption. Although slower than symmetric key encryption, this method ensures the key cannot accessed by a 3rd party while being transferred. Since the key has been transferred using a secure channel, a symmetric key can be used for data exchange. In some cases, data exchange may be done using public key encryption. If this is the case, often the data exchange will be done using a small key size to reduce the processing time. The second reason that both may be used is when a symmetric key is used and the key needs to be provided to multiple users. For example, if you are using encryption file system (EFS) this allows multiple users to access the same file, which includes recovery users. In order to make this possible, multiple copies of the same key are stored in the file and protected from being read by encrypting it with the public key of each user that requires access.

Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Chaotic cryptography is the application of the mathematical chaos theory to the practice of the cryptography, the study or techniques used to privately and securely transmit information with the presence of a third-party or adversary. The use of chaos or randomness in cryptography has long been sought after by entities wanting a new way to encrypt messages. However, because of the lack of thorough, provable security properties and low acceptable performance, chaotic cryptography has encountered setbacks. In order to use chaos theory efficiently in cryptography, the chaotic maps should be implemented such that the entropy generated by the map can produce required Confusion and diffusion. Properties in chaotic systems and cryptographic primitives share unique characteristics that allow for the chaotic systems to be applied to cryptography. If chaotic parameters, as well as cryptographic keys, can be mapped symmetrically or mapped to produce acceptable and functional outputs, it will make it next to impossible for an adversary to find the outputs without any knowledge of the initial values. Since chaotic maps in a real life scenario require a set of numbers that are limited, they may, in fact, have no real purpose in a cryptosystem if the chaotic behavior can be predicted. One of the most important issues for any cryptographic primitive is the security of the system. However, in numerous cases, chaos-based cryptography algorithms are proved unsecure. The main issue in many of the cryptanalyzed algorithms is the inadequacy of the chaotic maps implemented in the system. The concept of chaos cryptography or in the other words chaos-based cryptography can be divided into two major groups: the asymmetric and symmetric chaos-based cryptography. The majority of the symmetric chaos-based algorithms are based on the application of discrete chaotic maps in their process. Bourbakis and Alexopoulos in 1991 proposed supposedly the earliest fully intended digital image encryption scheme which was based on SCAN language. Later on, with the emergence of chaos-based cryptography hundreds of new image encryption algorithms, all with the aim of improving the security of digital images were proposed. However, there were three main aspects of the design of an image encryption that was usually modified in different algorithms (chaotic map, application of the map and structure of algorithm). The initial and perhaps most crucial point was the chaotic map applied in the design of the algorithms. The speed of the cryptosystem is always an important parameter in the evaluation of the efficiency of a cryptography algorithm, therefore, the designers were initially interested in using simple chaotic maps such as tent map, and the logistic map. However, in 2006 and 2007, the new image encryption algorithms based on more sophisticated chaotic maps proved that application of chaotic map with higher dimension could improve the quality and security of the cryptosystems. The unpredictable behavior of the chaotic maps can be used in the generation of random numbers. Some of the earliest chaos-based random number generators try to directly generate random numbers form the logistic map.

QUANTSTAMP| Quantstamp Review: What Is QSP Tokens?
QUANTSTAMP| Quantstamp Review: What Is QSP Tokens? ◄ Quantstamp Website ► www.quantstamp.com Just what is Quantstamp? Quantstamp is a security-auditing method for clever agreements. As a dapps system, Ethereum has actually shown its safety time after time. Nonetheless, dapps and also wise agreements in addition to Ethereum might still have insects where destructive gamers could trigger chaos on the network. Both most remarkable instances of these being the $55 million DAO hack as well as the $30 million Parity budget insect. These concerns not just impact individuals that have actually had their funds taken, yet they likewise reduce the reliability of the whole community. Creating wise agreements is currently a laborious. Like other computer system programs, creating them with no pests is near difficult. To include gas to the fire, the price at which wise agreements are being composed (approximated 10 million by the end of the year) is surpassing the sources should investigate them. Despite having durable safety bookkeeping, a tiny pest might slide via the fractures creating disaster later on. Just how does Quantstamp function? Although the group is concentrating on Ethereum currently, they're constructing the Quantstamp method in a manner that's system agnostic. This suggests that it could become utilized on various other wise agreement systems like Lisk as well as NEO. The Quantstamp procedure has a two-pronged method to protection bookkeeping: Automated software program confirmation system Automated bounty payment system To make certain no criminals are sending harmful recognition software application, Factors should be enacted inning accordance with the administration device (much more on this later). Running the Recognition Node takes a considerable quantity of calculating power. As a result of this, Validators additionally get QSP repayment for offering computer power to the network. To make certain that Validators do not act maliciously, they have to bet their QSP symbols to gain their benefit. Bounty Payments When you send your wise agreement for bookkeeping, you likewise consist of a collection of QSP symbols for bounty benefits as well as a due date for when Insect Finders could send concerns. The bounty due date incentive dimension depends on you. If the due date passes without any discovered insects, the QSP bounty incentive is gone back to you. Quantstamp does not ensure perfect code hereafter procedure, yet they do guarantee customers that the automated screening and also crowdsourced bug-hunting considerably minimize concerns. Procedure Administration QSP token owners regulate procedure, recognition wise agreements, as well as Recognition Node upgrades. The administration version utilizes a time-locked multisig where any type of token owner could recommend a modification. The even more ballots a modification has, the quicker it happens. Adjustments authorized by all participants happen within a hr. This moment increases with each 5% of participants that do not elect as well as quadruples for each and every 5% that ballot versus it. Proof-of-Caring Quantstamp makes use of an internal produced Proof-of-Caring system to compensate neighborhood participants as well as dedicated QSP token owners. As soon as you send your evidence, you'll get an airdrop from an ICO that Quantstamp has actually examined. This evidence includes holding your symbols in a budget (not an exchange) for a specific quantity of time, adding to social networks outreach, and/or other area tasks. Quantstamp group & progression The Quantstamp group contains 22 participants as well as consultants with over 500 Google Scholar citations. Steven Stuart (CTO) and also Richard Ma (Chief Executive Officer) started the group in June of 2017. Stuart functioned 5 years in Canada's cryptologic company in the Division of National Protection as well as formerly started Numerous Trees, a startup that makes use of GPUs for Big Information analytics and also artificial intelligence. Ma constructed production-grade combination as well as recognition screening software application at the Bitcoin HFT Fund. Throughout his time there, his trading systems had no significant concerns and also managed numerous bucks in financial investment resources. Verdict Quantstamp is making clever agreements extra safeguard via automated software application screening and also a system of pest bounties. Although beginning with Ethereum, the group is constructing the method to be readily available on any kind of DApp system in the future. In a market where safety is a main problem and also insects have actually triggered the burglary of countless bucks, Quantstamp needs to assist to legitimize blockchain tasks as well as make sure that large wise agreement hacks are a distant memory.

EC-130H Compass Call Refuels from KC-135 - 2012
An electronic warfare EC-130H Compass Call aircraft takes fuel from an Ohio Air National Guard KC-135R Stratotanker crewed by members of the Utah Air National Guard's 191st Air Refueling Squadron in this classic video from the vault, made in 2012. Here's a 2015 USAF explanation of the aircraft: "The EC-130H Compass Call is an airborne tactical weapon system using a heavily modified version of the C-130 Hercules airframe. The system disrupts enemy command and control communications and limits adversary coordination essential for enemy force management. The Compass Call system employs offensive counter-information and electronic attack (or EA) capabilities in support of U.S. and Coalition tactical air, surface, and special operations forces. The EC-130H, EA-6B or EA-18G, and F-16CJ, form the Suppression of Enemy Air Defense (SEAD) triad". The USAF description continues: "The EC-130H aircraft carries a combat crew of 13 people. Four members are responsible for aircraft flight and navigation (aircraft commander, co-pilot, navigator and flight engineer), while nine members operate and employ the EA mission equipment permanently integrated in the cargo/mission compartment. The mission crew includes the mission crew commander (electronic warfare officer), weapon system officer (electronic warfare officer), mission crew supervisor (an experienced cryptologic linguist), four analysis operators (linguists), one acquisition operator and an airborne maintenance technician".

EC-130H Compass Call Air Refueling
Video by Senior Airman Robert Harnden 2nd Combat Camera SquadronMembers of the 191st Air Refueling Squadron, 151st Air Refueling Wing, from the Utah Air National Guard maintain proficiency. The crew members of the KC-135R Stratotanker aircraft, from the Ohio Air National Guard, refuel an EC-130H Compass Call aircraft of the 755th Operational Support Squadron from Davis-Monthan Air Force Base, Arizona. Mission The EC-130H Compass Call is an airborne tactical weapon system using a heavily modified version of the C-130 Hercules airframe. The system disrupts enemy command and control communications and limits adversary coordination essential for enemy force management. The Compass Call system employs the offensive counterinformation and electronic attack or EA capabilities in support of U.S. and Coalition tactical air, surface, and special operations forces. Programmed upgrades will expand its mission by procuring a secondary EA capability against early warning and acquisition radars. Features The EC-130H aircraft carries a combat crew of 13 people. Four members are responsible for aircraft flight and navigation (aircraft commander, co-pilot, navigator and flight engineer), while nine members operate and employ the EA mission equipment permanently integrated in the cargo/mission compartment. The mission crew includes the mission crew commander (electronic warfare officer), weapon system officer (electronic warfare officer), mission crew supervisor (an experienced cryptologic linguist), four analysis operators (linguists), one acquisition operator and an airborne maintenance technician. The EC-130H fleet is composed of a mix of Block 20, Block 30 and state-of-the-art Block 35 aircraft, which has achieved initial operational capability. All aircraft will transition to the Block 35 baseline configuration by fiscal 2011. The Block 30 EC-130H upgrade achieved a major redesign of the mission compartment and operating system software of the Block 20 aircraft. Its primary focus was to provide a reprogrammable capability against target C2 systems. The Block 35 EC-130H upgrade provides the Air Force with additional capabilities to jam communication, Early Warning/Acquisition radar and navigation systems through higher effective radiated power, extended frequency range and insertion of digital signal processing. Block 35s will have the flexibility to keep pace with adversary use of technology. It is highly reconfigurable and permits incorporation of clip-ins with less crew impact. It promotes enhanced crew proficiency, maintenance and sustainment with a common fleet configuration, new operator interface, increased reliability and better fault detection. The Compass Call integrates into tactical air operations at any level. The versatile and flexible nature of the aircraft and its crew enable the power of electronic combat to be brought to bear in virtually any combat situation. Background Airborne electronic warfare consists of three major players forming a triad of capability. The EC-130H Compass Call, EA-6B Prowler and F-16CJ Fighting Falcons suppress enemy air defenses while jamming communications, radar and command and control targets. Compass Call is in demand with all unified commands, and therefore, subject to worldwide deployment in support of operations on very short notice. The Compass Call was delivered to the Air Force in 1982, and had its first flight in 1981. The aircraft has demonstrated a powerful effect on enemy command and control networks in multiple military operations including Kosovo, Haiti, Panama, Iraq, Serbia and Afghanistan. All Compass Call aircraft are assigned to Air Combat Command. The EC-130H Compass Call is operated by the 55 Electronic Combat Group (41st, 42nd and 43d Electronic Combat Squadrons) at Davis-Monthan Air Force Base, Ariz. Although located at Davis-Monthan, the group reports to the 55th Wing at Offutt AFB, Neb.

Blockchain: Distributed Trust - Bart Preneel
The Bitcoin ecosystem had a bumpy start, but driven in part by the demand created by the Silk Road and perhaps the Cyprus crisis, the impact grew quickly: the total value of bitcoins rose to several billion US$ in the first two years (currently it is around US$ 14 billion), hundreds of alternative cryptocurrencies (altcoins) were created and large mining entities were established, mostly in China. The ideas behind Bitcoin have opened up new approaches to cryptocurrencies, but also to distributed consensus, distributed naming, secure timestamping and commitment. One of the aspects that have drawn the most interest is the smart contract (that is, cryptographically enforceable agreements) on top of the Bitcoin ecosystem (or on other systems such as Ethereum). Even if some observers predict that the Bitcoin ecosystem will disappear or become irrelevant, the core ideas have already made a major impact. Unlike any other payment system or cryptocurrency created before, Bitcoin allows for fully decentralized generation of currency and fully decentralized verification of transactions. The core idea is the blockchain, a public ledger that registers all transactions under the form of a hash chain; the blockchain describes the state of the system, that is, it specifies who owns which amount. Transactions themselves are validated based on a scripting language, which creates some flexibility. In a distributed system, a central problem is how to achieve consensus (e.g., how to deal with double-spending transactions). Transactions are broadcast over a low-latency peer-to-peer network that offers some robustness against censoring or sabotage. This approach allows the Bitcoin ecosystem to achieve distributed consensus in a practical way assuming that players are rational (something which is known to be unachievable without additional assumptions such as rationality) albeit at the cost of a major computational effort in terms of mining. While the financial industry is less interested in the anarchistic aspects of the Bitcoin ecosystem (the governance model and the uncontrolled money supply), the distributed consensus idea is very appealing and is believed to have a very high business potential for a large number of financial transactions and interactions. In 2015, about US$ 1 billion was invested in venture capital in the area of blockchain and cryptocurrencies and the Aite Group predicted in 2016 that blockchain market could be worth as much as US$ 400 million in annual business by 2019. The idea of a public ledger for timestamping and registering documents using hash chains is more than 25 years old, as witnessed by the efforts of Surety Technologies in the early 1990 and the ISO standardization in this area in the mid 1990s –- but these earlier approaches did use a central authority to register all transactions. Bitcoin has inspired many actors to revisit those ideas by `taming’ the Bitcoin ecosystem into a private or permissioned ledger, where only a few selected actors have control over new currencies or verification of transactions (to get rid of distributed control) and where access to the ledger can be restricted (to get rid of full transparency). Some of the notable developments in this context are the open source initiative of IBM that is called Hyperledger and Intel's experimental Sawtooth Lake architecture. Professor Bart Preneel of KU Leuven heads the imec-COSIC (COmputer Security and Industrial Cryptography) research group. His main research areas are information security and privacy with a focus on cryptographic algorithms and protocols and efficient and secure implementations. He undertakes industrial consulting for major players in the finance, telco and hardware industry and has co-designed the Belgian eID and e-voting scheme. He is active in international standardization . Professor Preneel has served as Director, (1997-present), Vice President (2002-2007) and President (2008-2013) of the International Association for Cryptologic Research (IACR) and is co-founder and chairman of LSEC vzw (Leuven Security Excellence Consortium).

US cyber soldiers
The US Army will soon send teams of cyber warriors to the battlefield, officials said Wednesday, as the military increasingly looks to take the offensive against enemy computer networks. While the Army's mission is generally to "attack and destroy," the cyber troops have a slightly different goal, said Colonel Robert Ryan, who commands a Hawaii-based combat team. "Not everything is destroy. How can I influence by non-kinetic means? How can I reach up and create confusion and gain control?" he told reporters. The cyber soldiers have been integrated for six months in infantry units, and will tailor operations according to commanders' needs, said Colonel William Hartman of the Army's Cyber Command. The Army has for the past three years conducted training for such operations at a huge center in southern California. Hartman didn't give details on what the cyber troops can achieve, except to say that they would be scooping up information or intercepting planned attacks. According to the New York Times, CYBERCOM has previously placed "implants" in ISIS networks that let experts monitor the group's behavior and ultimately imitate or alter commanders' messages so they unwittingly direct fighters to areas likely to be hit by drone or plane strikes. Another technique likely being employed is a common type of cyber attack known as a denial of service. Cyber Command had previously been a subordinate part of the US Strategic Command, but President Donald Trump in August ordered the Pentagon to elevate it to its own command, in a sign of its growing importance.
