One of the hottest topics in current crypto research is Post-Quantum Cryptography. This branch of cryptography addresses asymmetric crypto systems that are not prone to quantum computers. Virtually all asymmetric crypto systems currently in use (Diffie-Hellman, RSA, DSA, and Elliptic Curve Crypto Systems) are not Post-Quantum. They will be useless, once advanced quantum computers will be available. Quantum computer technology has made considerable progress in recent years, with major organisations, like Google, NSA, and NASA, investing in it. Post-Quantum Cryptography uses advanced mathematical concepts. Even if one knows the basics of current asymmetric cryptography (integer factorisation, discrete logarithms, …), Post-Quantum algorithms are hard to understand. The goal of this presentation is to explain Post-Quantum Cryptography in a way that is comprehensible for non-mathematicians. Five families of crypto systems (as good as all known Post-Quantum algorithms belong to these) will be introduced: Lattice-based systems: The concept of lattice-based asymmetric encryption will be explained with a two-dimensional grid (real-world implementations use 250 dimensions and more). Some lattice-based ciphers (e.g., New Hope) make use of the Learning with Error (LWE) concept. I will demonstrate LWE encryption in a way that is understandable to somebody who knows Gaussian elimination (this is taught at middle school). Other lattice-based systems (especially NTRU) use truncated polynomials, which I will also explain in a simple way. Code-based systems: McEliece and a few other asymmetric ciphers are based on error correction codes. While teaching the whole McEliece algorithm might be too complex for a 44CON presentation, it is certainly possible to explain error correction codes and the main McEliece fundamentals. Non-commutative systems: There are nice ways to explain non-commutative groups and the crypto systems based on these, using everyday-life examples. Especially, twisting a Rubik’s Cube and plaiting a braid are easy-to-understand group operations a crypto system can be built on. Multivariate systems: Multivariate crypto can be explained to somebody who knows Gaussian elimination. Hash-based signatures: If properly explained, Hash-based signatures are easier to understand than any other asymmetric crypto scheme. I will explain these systems with cartoons, drawings, photographs, a Rubik’s Cube and other items. In addition, I will give a short introduction to quantum computers and the current Post-Quantum Crypto Competition (organised by US authority NIST).

The Zimmerman Telegram During times of war, messages are often sent in code to prevent the enemy from finding out about secret plans. Spies are everywhere, and if the message is ever decoded by an unintended recipient, it can change the course of history… and that’s exactly what happened in 1917. 9. The Battle of Midway The Battle of Midway, which took place between the 4th and 7th of June, 1942, was one of the American military’s biggest victories over the Japanese navy during the second world war. In this battle over 3,000 Japanese sailors lost their lives and 4 aircraft carriers were destroyed, while the Americans lost 300 sailors and one carrier. It could have all been different, though, had US cryptographers not intercepted and decoded Japanese transmissions. 8. The Babington Plot The Babington plot was an attempt, in 1586, to assassinate Queen Elizabeth the First, protestant daughter of King Henry VIII. The goal was to replace her on the throne with Mary Queen of Scots, who was her Roman Catholic cousin. On July 6th that year, Anthony Babington, encouraged by support from abroad (mostly Spain) wrote a long letter to Mary, who at the time was already in prison. 7. Olivier Levasseur According to legend, the notorious French Pirate, Olivier Levasseur, managed to acquire a huge fortune during his piracy across the Caribbean and West Africa- most notably in 1721 when he and his crew captured a Portuguese treasure ship that had become grounded on a sandbar during a storm- an act that is said to be one of the greatest paydays in the history of piracy. 6. Poe’s Challenge Edgar Allan Poe was a renowned writer and poet, known for his stories of mystery… but he was also fascinated with ciphers and codes. He even wrote a story, The Gold Bug, about the solution to one. In 1840, he wrote an article for Graham's magazine called ‘A Few Words on Secret Writing' in which he invited readers to send him coded messages for him to decipher. 5. Linear B In 1900, among the ruins of a Bronze age palace in Knossos, Greece, archaeologists found a script that resembled nothing that had ever been seen before. Containing images of swords, chariots, and countless other small pictograms, this system of writing became known as Linear B and would prove to be a mystery for the following 50 years. 4. Frank Sidebottom Frank Sidebottom was the papier-mâché headed comedy persona of English musician Chris Sievey. Throughout his career in the 80s and 90s, he fronted tv and radio shows and even reported for the local news. He created numerous newsletters and writings over this time, too, and these were often accompanied by symbols around them… ones that people long suspected had a meaning, but they couldn't work out what it was. 3. Chaocipher The Chaocipher was created by John Francis Byrne in 1918 and was what he described as being unbreakable… yet simple. So simple, in fact, that it only required two rotating discs that were small enough to fit into a cigar box and could be operated by a ten-year-old. He offered a cash reward to anyone who could crack it, but this is something that would never be claimed. 2. The Copiale Cipher Created in the 1730s, the Copiale cipher is a 105-page manuscript that has baffled researchers ever since…That is until 2011 when it was finally decoded. Consisting of 75,000 handwritten characters; including arrows, shapes, runes, math symbols, roman letters, and Greek letters… there were only two examples of plain text in the entire book. 1. The Enigma Code The Enigma was an enciphering machine used by the German armed forces during the second world war to send secure messages. Early on, Polish mathematicians had figured out how to read these messages, but once the Germans realized this, they began to change the cipher system daily, making it virtually impossible to decipher.

Modular arithmetic especially the properties of congruence are an important tool in arriving at quick solutions to a variety of problems. In this video Mayank unravels this concept of Congruence starting with the basic concepts and then explaining the 5 key properties of Congruence (≡): a+c ≡ (b+d)mod N (Remainder of Sums ≡ Sum of Remainders) a-c ≡ (b-d)mod N (Remainder of Difference ≡ Difference of Remainders) ac ≡ (bd)mod N (Remainder of Products ≡ Products of Remainders) a^e ≡ b^e mod N (Remainder of Exponent ≡ Exponent of Remainders) a/e ≡ b/e (mod N/gcd(N,e)) (However, don’t do division without writing basic equation Mayank applies these concepts to arrive at quick solutions for 7 representative problems - reducing seemingly impossible math involving large numbers to mere seconds.

Today we’re going to talk about how to keep information secret, and this isn’t a new goal. From as early as Julius Caesar’s Caesar cipher to Mary, Queen of Scots, encrypted messages to kill Queen Elizabeth in 1587, theres has long been a need to encrypt and decrypt private correspondence. This proved especially critical during World War II as Allan Turing and his team at Bletchley Park attempted to decrypt messages from Nazi Enigma machines, and this need has only grown as more and more information sensitive tasks are completed on our computers. So today, we’re going to walk you through some common encryption techniques such as the Advanced Encryption Standard (AES), Diffie-Hellman Key Exchange, and RSA which are employed to keep your information safe, private, and secure. Note: In October of 2017, researchers released a viable hack against WPA2, known as KRACK Attack, which uses AES to ensure secure communication between computers and network routers. The problem isn't with AES, which is provably secure, but with the communication protocol between router and computer. In order to set up secure communication, the computer and router have to agree through what's called a "handshake". If this handshake is interrupted in just the right way, an attacker can cause the handshake to fault to an insecure state and reveal critical information which makes the connection insecure. As is often the case with these situations, the problem is with an implementation, not the secure algorithm itself.

This clip from the 2008 Royal Institution Christmas Lectures shows a simple demonstration of how two people can agree on a secret key, even though all of their communications are carried out in public. In the electronic world, secret key exchange allows computers to communicate securely, and is used, for example, when you give your credit card information to an on-line shop.

Beware my brothers and sisters, man try daily to master the text without the Set-Apart Spirit the Almighty Father Yahuah sent in Yahusha's name (referencing John 14:26); without life, trying to use scripture for personal gain will come to naught. Let us promote the ability to grow in a relationship with He who brings the letter to life; Yahusha is His name sent by the Almighty Father Yahuah.

Dr. Orr Dunkelman of Haifa University Lecture at TCE Summer School 2013, July 25, 2013 When Cryptography is not the Answer (even when it is) Since modern cryptography has emerged in the mid 70's, it developed a huge set of solutions to many of the security problems: from secure algorithms for communication, to identification of entities, from integrity assurance for programs, to methods for evaluating a function without revealing it. Despite these advances, even the security challenges that were solved by cryptography are still affecting our everyday life: from using old and insecure algorithms, through key management issues, to problems in the interaction between the cryptography and the system where it resides. In this talk we shall consider several examples of such issues, of the gaps between "what is already solved by cryptographers" and "what the security professionals see as unsolved (if not unsolvable)". We will try to isolate the sources for such problems, and look for the changes, both in the technical level and in the perception level, needed from both sides of the security equation (cryptographers and security professionals), to overcome these issues in the future.

A protocol is a set of rules. It describes the proper protocol for certain actions and behaviors. David Johnston, the Governor General of Canada, broke protocol when he touched Queen Elizabeth II on the steps of Canada House on Trafalgar Square in London. The Queen was 91 years old at the time and the Governor General touched her arm to protect her from falling on the steps. It is protocol to not touch a member of Britain’s royal family. methods. Specific topics include: 1. Overview of communications channels used in power systems. 2. Review of cryptographic protocols and how they work. 3. How cryptography can impact monitoring, control, and protection communications. 4. Differences between substation communications systems and corporate The confidentiality and integrity protections offered by cryptographic protocols such as SSL/TLS can protect communications from malicious eavesdropping and tampering. Authenticity protections provide assurance that users are actually communicating with the systems as intended. For example, are you sending your Often cryptographic algorithms and protocols are necessary to keep a system secure, particularly when communicating through an untrusted network such as the Internet. Where possible, use cryptographic techniques to authenticate information and keep the information private (but don't assume that simple encryption SUMMARY. This project will focus on research in cryptology at an advanced international level. Project topics will be analysis and construction of symmetric and asymmetric cryptographic algorithms and protocols. In particular we will use our knowledge involving deep techniques from coding theory on cryptological. What is a cryptographic protocol? A cryptographic protocol is a protocol executed by several distant agents through a network where the messages or part of the messages are produced using cryptographic functions (encryption, hashing, etc.). Cryptographic protocols are used for various purpose between the agents:. May 7, 2006 - This is regarded as offensive because of the malicious payload normally embedded in the virus, and because of the use of anti-anti-virus techniques For instance, on networks some layer 2 protocols are based on crypto (WEP, WPA/TKIP, and others), as are some upper layer protocols (IPSec, SSH, SSL, primitives such as commutative encryption. We give a list of some relevant al- gebraic properties of cryptographic operators, and for each of them, we provide examples of protocols or attacks using these properties. We also give an overview of the existing methods in formal approaches for analyzing cryptographic proto-. Using cryptographic techniques, it may be possible to allow intermediate results in a distributed algorithm to be certified independently of who provides them, reducing themes of complexity theory, e.g., interactive provability, average vs. worst-case complexity, and the inherent communication costs of multiparty protocols. Web is an electronic protocol which allows people to communicate mail, information, and commerce through a digital medium. This new method of information exchange has caused a tremendous need for information security. A thorough understanding of cryptography and encryption will help people develop better ways to etc. The analysis techniques discussed in this survey assume per- fect cryptography. This means that cryptographic primitives are considered as black boxes satisfying certain properties, as described in section 2.1. below. This assumption by it- self does not ensure security of the protocols.

Russian President Vladimir Putin has authoritatively expressed that Russia will issue its own 'CryptoRuble' at a shut entryway meeting in Moscow, as per nearby news sources. The news got through Minister of Communications Nikolay Nikiforov. As per the authority, the state issued digital money can't be mined and will be issued and controlled and kept up just by the specialists. The CryptoRubles can be traded for standard Rubles whenever, however in the event that the holder can't clarify where the CryptoRubles originated from, a 13 percent expense will be demanded. A similar assessment will be connected to any earned contrast between the cost of the buy of the token and the cost of the deal. Nikiforov stated: "I unhesitatingly proclaim that we run CryptoRuble for one basic reason: on the off chance that we don't, at that point following 2 months our neighbors in the EurAsEC will." Grasping and dismissing While the declaration implies that Russia will enter the cryptographic money world, it is not the slightest bit an assertion or legitimization of Bitcoin or some other decentralized digital money. Despite what might be expected, Putin as of late required an entire prohibition on all cryptographic forms of money inside Russia. The announcement from Putin appeared to be evidently to negate the prior remarks from different priests who appeared to be master crypto, however just with controls, and additionally Putin's current gatherings with Buterin and others. Presently, with the issuance of the CryptoRuble, the evident logical inconsistency has been clarified. cryptocurrency cryptocurrency market cryptosporidium cryptography cryptorchidism cryptocompare cryptopia cryptocurrencies cryptozoology cryptocurrency mining crypto crypto news crypto mining crypto wallet crypto exchange crypto calculator crypto reddit crypto meaning crypto aero crypto arbitrage crypto asset fund crypto assets crypto asset management crypto alerts crypto anarchist crypto arbitrage bot crypto api cryptanalysis a crypto botanical champion a cryptocurrency that's not bitcoin a cryptonet a cryptographic self test was performed a crypto miner for your website a crypto nerd's imagination a cryptography expert is deciphering a cryptocurrency a cryptographic evaluation of ipsec a crypto miner crypto bubble crypto bot crypto blog crypto bacteria crypto bitcoin crypto bank crypto bobby crypto bear market crypto buddy crypto blockchain b cryptoxanthin b. cryptococcus neoformans cryptojs b.clamp is not a function cryptowall.b cryptolocker.b cryptodefense.b cryptowall 3.b crypto db_dump suite b cryptography amphotericin b cryptococcal meningitis cryptocurrency news crypto capital cryptocurrency exchange crypto crash c crypto library c cryptographically secure random number c cryptography c crypto lib c-crypto-comp-1.0 c cryptography tutorial c crypto api c. cryptococcus neoformans c cryptography example c crypto example crypto definition crypto disease crypto debit card crypto day trading cryptodaily crypto destroy all humans crypto diarrhea crypto discord crypto derivatives crypto dash d cryptocurrency decryptonite decryptor kryptonite d lock crypto-d crypto.d.ts d wave cryptography d. stinson cryptography theory and practice dnotes crypto cryptogramme d'une carte bancaire crypto etf crypto exchange rates crypto exchanges by volume crypto exchange reviews cryptoeconomics crypto ethereum crypto eos crypto exchange app crypto exchange list e cryptocurrency e crypto source e) cryptology e crypto libertas cryptolocker.e cryptome cryptography ebook cryptography e commerce crypto e juice cryptoflex e-gate crypto fund crypto forum crypto fud crypto fantasy sports crypto faucets crypto facilities crypto futures crypto forecast crypto fiat crypto finance f cryptocurrency f# cryptography f cryptosporidium f_crypto.dll cryptolocker.f cryptowall f-secure cryptolocker.f decrypt cryptonite f-droid cryptolocker.f symantec crypto f360 crypto group limited crypto games crypto group crypto girl crypto graphs crypto graffiti crypto gas crypto gold crypto gram crypto gecko cryptolocker.g crypto g trojan.cryptolocker.g removal trojan.cryptolocker.g (symantec) symantec cryptolocker.g cryptolocker g data cryptowall g data g smart crypto (gnu crypto g&d starsign crypto usb token crypto hedge fund crypto hardware wallet crypto hedge crypto hash crypto hard wallet crypto hustle crypto hodl

In this session, we have discussed MATHEMATICS AS CAREER. If we see our daily day to day lifestyle it works on Mathematics. A simple example is the Time, we keep boundaries to do a particular work in a particular time period and we have to start a new work and end that in some period of time, all this is called calculating the time and adjusting the work for our need to manage things but if we see technically it is related to mathematics which is called the Time Management. In Education, The candidates should complete their 10+2 or its equivalent exam in science stream with Mathematics as one of the subjects. B.Sc. , M.Sc. , B.Tech, BS- 4 YEARS, M. Tech, M.Phil. and Ph.D. are some of the degrees you can complete. B.Sc. Mathematics Colleges: 1. Indira Gandhi National Open University, Delhi 2. Maharshi Dayanand University, Rohtak 3. Adarsh Mahavidyalaya, Osmanabad 4. Loyola College, Chennai Tamilnadu. 5. St.Xavier’s college Mumbai Maharashtra 6. Christ University Bangalore Karnataka 7. Madras Christian college Chennai Tamilnadu Master of Philosophy or M.Phil in Mathematics is an advanced postgraduate research degree which offers students with a stretch to research on particular fields of the chosen subject. Duration, of course, is 2 years Some of the M.Phil colleges University of Delhi, Banaras Hindu University, Jawaharlal Nehru University, University of Calcutta, Dr. BR Ambedkar University The best way to get a good college for Ph.D. is to sit in CSIR-NET and UGC-NET exams for some of the college's GATE is also used as a prerequisite. For Ex. ISI Kolkata uses GATE score for admission in its Ph.D. Maths program conducted for Ph.D. Scholarships. ENTERPRENEURIAL OPPORTUNITIES are PRIVATE FINANCIAL CONSULTANT. COMPUTING & ICT FIRMS. EDUCATIONAL INSTITUTIONS. EQUITY RESEARCH FIRMS. QUANTUM CRYPTOGRAPHY COMPANIES. 2. Mathematics helps in the progression of technological innovation in day to day life. Learning mathematics helps in perception development of individuals in their daily life which help to achieve their goal in life, which include the term like addition, subtraction, multiplication, and division. The disadvantage of mathematics can be overridden by the easy way of learning or a better approach of teaching to the students in their basics.

Anastasia from Publica keeps exploring how blockchain and cryptocurrency technologies keep coming closer to becoming a part of our daily lives. 1. A new crypto-collectibles token launched in partnership with the Major League Baseball Players Association. It’s called the Player Token. Player Tokens are the next step in the collectible experience. They combine traditional baseball trading cards with digital assets. These digital assets They come in different ‘packs’ just like traditional trading cards. Each has a unique ID that can be traced on the blockchain. This opens up fun new aspects of the experience because you can see details like the minting date and previous ownership. Packs will feature tokens representing seventy-three all-star players from all thirty major league teams. Each will be minted in a fixed number of tokens distributed randomly among the packs. 2. West Virginia is rolling out a mobile app so American military workers may cast their votes for upcoming elections. With help from trusted blockchain technology. They call their app Voatz. And they’ve been testing a pilot project for some time. The office of State Secretary Mac Warner says, and I quote, four audits of various components of the tool, including its cloud and blockchain infrastructure, revealed no problems. Their app is intended primarily for military personnel stationed overseas. Although the Voatz project isn't meant to replace traditional voting ballots, it still makes a nice statement about the power of blockchain and its adoption in well-known places. Blockchains are known for immutability, so voting is an obvious place to look for the benefits of blockchain technology. Sports and politics are showing up among the busiest blockchain and cryptocurrency adopters. 3. For you video game fans. I’m talking about the hugely popular game called ‘No Man's Sky.’ In this action survival game, two planets are hiding 0.004 BTC with a promise of more hidden Bitcoins to come. Jon Creasy - a crypto aficionado hopes this cryptocurrency element will inspire more gaming and crypto fans to follow his example. Jon believes gamers can bring cryptocurrency far along towards mass adoption. --- What is Publica? Publica is the first digital publishing platform to use blockchain technology to innovate how books are funded, distributed, bought, and read.

What is the mathematical secret behind the barcodes we find on our books? How does it self-check for mistakes? In this extract from his lecture on 'Codebreaking in Everyday Life', John D. Barrow, Gresham Professor of Geometry and Professor of Mathematical Science at the University of Cambridge, explains the maths behind this piece of code we find in our everyday lives. This is the 11th part of 'Codebreaking in Everday Life'. The full lecture is available (in 13 parts) here on YouTube, or it can be downloaded (like all of our lectures) in its complete form from the Gresham College website, in video, audio or text formats: http://www.gresham.ac.uk Gresham College has been giving free public lectures since 1597. This tradition continues today with all of our five or so public lectures a week being made available for free download from our website.

Most working engineers view machine-checked mathematical proofs as an academic curiosity, if they have ever heard of the concept at all. In contrast, activities like testing, debugging, and code review are accepted as essential. They are woven into the lives of nearly all developers. In this talk, I will explain how I see machine-checked proofs enabling new everyday activities for developers of computer software and hardware. These activities have the potential to lower development effort dramatically, at the same time as they increase our assurance that systems behave correctly and securely. I will give a cosmological overview of this field, answering the FAQs that seem to stand in the way of practicality; and I will illustrate the principles with examples from projects that you can clone from GitHub today, covering the computing stack from digital hardware design to cryptographic software and applications. Today's developers of computer software and hardware are tremendously effective, compared to their predecessors. We have found very effective ways of modularizing and validating our work. The talk is about ammunition for these activities from a perhaps-unexpected source. Modularity involves breaking a complex system into a hierarchy of simpler pieces, which may be written and understood separately. Structured programming (e.g., using loops and conditionals instead of gotos) helps us read and understand parts of a single function in isolation, and data abstraction lets us encapsulate important functionality in objects, with guarantees that other code can only access the private data by calling public methods. That way, we can convince ourselves that the encapsulated code upholds certain essential properties, regardless of which other code it is linked with. Systematic unit testing also helps enforce contracts for units of modularity. Each of these techniques can be rerun automatically, to catch regressions in evolving systems, and catch those regressions in a way that accurately points the finger of responsibility to particular modules. Validation is an important part of development that encompasses testing, debugging, code review, and anything else that we do to raise our confidence that the system behaves as intended. Experienced engineers know that validation tends to take up the majority of engineering effort. Often that effort involves mentally taxing activities that would not otherwise come up in coding. One example is thinking about test-case coverage, and another is including instrumentation that produces traces to consult during debugging. It is not hard for working developers to imagine great productivity gains from better ways to break systems into pieces or raise our confidence in those pieces. The claim I will make in this talk is that a key source of such insights has been neglected: machine-checked mathematical proofs. Here the basic functionality is an ASCII language for defining mathematical objects, stating theorems about them, and giving proofs of theorems. Crucially, an algorithm checks that purported proofs really do establish the theorems. By going about these activities in the style of programming, we inherit usual supporting tools like IDEs, version control, continuous integration, and automated build processes. But how could so esoteric a task as math proofs call for that kind of tooling, and what does it have to do with building real computer systems? I will explain a shared vision to that end, developed along with many other members of my research community. Let me try to convince you that all of the following goals are attainable in the next 10 years. We will have complete computer systems implementing moderately complex network servers for popular protocols, proved to implement those protocols correctly, from the level of digital circuits on up. We will remove all deployed code (hardware or software) from the trusted computing base, shifting our trust to much smaller specifications and proof checkers. Hobbyists will be able to design new embedded computing platforms by mixing and matching open-source hardware and software components, also mixing and matching the proofs of these components, guaranteeing no bugs at the digital-abstraction level or higher, with no need for debugging. New styles of library design will be enabled by the chance to attach a formal behavioral specification to each library. For instance, rank-and-file programmers will able to assemble their own code for cryptographic protocols, with code that looks like reference implementations in Python, but getting performance comparable to what experts handcraft in assembly today. Yet that benefit would come with no need to trust that library authors have avoided bugs or intentional backdoors, perhaps even including automatic proofs of cryptographic security properties.
