Fang Song - A Note on Quantum Security for Post-Quantum Cryptography
 
25:55
IQC member Fang Song presented a talk titled: A Note on Quantum Security for Post-Quantum Cryptography at the 2014 PQCrypto conference in October, 2014. Abstract: Shor's quantum factoring algorithm and a few other efficient quantum algorithms break many classical crypto-systems. In response, people proposed post-quantum cryptography based on computational problems that are believed hard even for quantum computers. However, security of these schemes against quantum attacks is elusive. This is because existing security analysis (almost) only deals with classical attackers and arguing security in the presence of quantum adversaries is challenging due to unique quantum features such as no-cloning. This work proposes a general framework to study which classical security proofs can be restored in the quantum setting. Basically, we split a security proof into (a sequence of) classical security reductions, and investigate what security reductions are "quantum-friendly". We characterize sufficient conditions such that a classical reductions can be "lifted" to the quantum setting. We then apply our lifting theorems to post-quantum signature schemes. We are able to show that the classical generic construction of hash-tree based signatures from one-way functions that are resistant to efficient quantum inversion algorithms, there exists a quantum-secure signature scheme. We note that the scheme in [10] is a promising (post-quantum) candidate to be implemented in practice and our result further justifies it. Actually, to obtain these results, we formalize a simple criteria, which is motivated by many classical proofs in the literature and is straight-forward to check. This makes our lifting theorem easier to apply, and it should be useful elsewhere to prove quantum security of proposed post-quantum cryptographic schemes. Finally we demonstrate the generality of our framework by showing that several existing works (Full-Domain hash in the quantum random-oracle model [47] and the simple hybrid arguments framework in [23]) can be reformulated under our unified framework.

Adam Young, Malicious Cryptography - Exposing Cryptovirology (February 27, 2004)
 
55:51
From the CISR video library (http://www.cisr.us) Dr. Adam Young, Cigital Malicious Cryptography - Exposing Cryptovirology February 27, 2004 at the Naval Postgraduate School (http://www.nps.edu) ABSTRACT Cryptography is commonly regarded as an enabling technology. It allows for confidential information transmission over untrusted networks as well as the ability to prove the origin of messages. It is a technology that is critical in an on-line world. However, cryptography is also a very powerful disabling technology. In recent years there has been a significant amount of research into using well-known cryptographic paradigms and tools for the purposes of undermining the security of computer systems once internal access is acquired. This talk will give an overview of a new book that details this dark side of cryptography. The book is entitled "Malicious Cryptography: Exposing Cryptovirology," and is authored by Adam Young and Moti Yung (published by John Wiley & Sons). Some of the more noteworthy attacks that are described in the book are the following. It is shown how to use public key cryptography to mount reversible denial-of-service attacks. A virus attack is detailed in which the virus asymmetrically encrypts host data (that has not been backed-up). The effects of the attack can only be reversed if the attacker agrees to use his or her own private decryption key. It is shown how to devise a cryptovirus that steals data from a host machine without revealing that which is sought, even if the virus is under constant surveillance. It is shown how to design a password snatching cryptotrojan that makes it virtually impossible to identify the author when the encrypted passwords are retrieved. Furthermore, it is intractable to determine if the cryptotrojan is encrypting anything at all when all even when all of its actions are recorded and analyzed. Finally, cryptotrojans are described that attack industry-standard cryptosystems. By design, these Trojans give the attacker covert access to the private keys of users and are extremely robust against reverse-engineering. When implemented in tamper-resistant devices the theft cannot be detected by anyone save the attacker. The book also covers various countermeasures that can help protect against these attacks. About Dr. Adam Young Dr. Adam Young is a Research Scientist at Cigital. He is responsible for researching and developing software and techniques to help support the research goals for Cigital's research contracts. In his first year at Cigital, Adam has served as a primary investigator on a research project for the DoD. Adam Young recently worked for Lockheed Martin Global Telecommunications. Prior to this he was a Member of Technical Staff (MTS) at Lucent Technologies in the Secure Systems Research Division. Before joining Lucent he worked as a cryptography consultant for CertoCo (a spin-off of Banker's Trust). Dr. Young holds a BS in Electrical Engineering from Yale University, an MS in Computer Science from Columbia University, and a PhD in Computer Science from Columbia University that was awarded with Distinction. He gives invited talks regularly and will be giving an upcoming talk at the Palo Alto Research Center (PARC) on his forthcoming book [[i]]. He will also be giving an invited talk at the Sixth International Joint Meeting of the AMS and the Sociedad Matematica Mexicana (SMM), Special Session on Coding Theory and Cryptography, in Houston. The session is being held by Neal Koblitz. Dr. Young has also given invited talks at NYU, Bell Labs, and Sandia National Labs. He has taught computer science courses at Columbia University and is a member of the International Association for Cryptologic Research (IACR). He has published numerous papers on cryptography, computer security, and algorithmic number theory and his next paper will be presented in the Cryptographer's Track of the RSA Conference, 2004 [[ii]].

John MacCormick's Nine Algorithms That Changed the Future
 
03:46
Every day, we use our computers to perform remarkable feats. A simple web search picks out a handful of relevant needles from the world's biggest haystack: the billions of pages on the World Wide Web. Uploading a photo to Facebook transmits millions of pieces of information over numerous error-prone network links, yet somehow a perfect copy of the photo arrives intact. Without even knowing it, we use public-key cryptography to transmit secret information like credit card numbers; and we use digital signatures to verify the identity of the websites we visit. How do our computers perform these tasks with such ease? This is the first book to answer that question in language anyone can understand, revealing the extraordinary ideas that power our PCs, laptops, and smartphones. Using vivid examples, John MacCormick explains the fundamental "tricks" behind nine types of computer algorithms, including artificial intelligence (where we learn about the "nearest neighbor trick" and "twenty questions trick"), Google's famous PageRank algorithm (which uses the "random surfer trick"), data compression, error correction, and much more. These revolutionary algorithms have changed our world: this book unlocks their secrets, and lays bare the incredible ideas that our computers use every day. John MacCormick is a leading researcher and teacher of computer science. He has a PhD in computer vision from the University of Oxford, has worked in the research labs of Hewlett-Packard and Microsoft, and is currently a professor of computer science at Dickinson College.

This talk discards hand-wavy pop-science metaphors and answers a simple question: from a computer science perspective, how can a quantum computer outperform a classical computer? Attendees will learn the following: - Representing computation with basic linear algebra (matrices and vectors) - The computational workings of qbits, superposition, and quantum logic gates - Solving the Deutsch oracle problem: the simplest problem where a quantum computer outperforms classical methods - Bonus topics: quantum entanglement and teleportation The talk concludes with a live demonstration of quantum entanglement on a real-world quantum computer, and a demo of the Deutsch oracle problem implemented in Q# with the Microsoft Quantum Development Kit. This talk assumes no prerequisite knowledge, although comfort with basic linear algebra (matrices, vectors, matrix multiplication) will ease understanding.

Subscribe my channel. https://www.youtube.com/dashboard?o=U https://www.blogger.com/blogger.g?blogID=3311469186913892104#allposts Factorization or factoring is the decomposition of an object (for example, a number, a polynomial, or a matrix) into a product of other objects, or factors, which when multiplied together give the original. For example, the number 15 factors into primes as 3 × 5, and the polynomial x2 − 4 factors as (x − 2)(x + 2). In all cases, a product of simpler objects is obtained. The aim of factoring is usually to reduce something to “basic building blocks”, such as numbers to prime numbers, or polynomials to irreducible polynomials. Factoring integers is covered by the fundamental theorem of arithmetic and factoring polynomials by the fundamental theorem of algebra. Viète's formulas relate the coefficients of a polynomial to its roots. The opposite of polynomial factorization is expansion, the multiplying together of polynomial factors to an “expanded” polynomial, written as just a sum of terms. Integer factorization for large integers appears to be a difficult problem. There is no known method to carry it out quickly. Its complexity is the basis of the assumed security of some public key cryptography algorithms, such as RSA. A matrix can also be factorized into a product of matrices of special types, for an application in which that form is convenient. One major example of this uses an orthogonal or unitary matrix, and a triangular matrix. There are different types: QR decomposition, LQ, QL, RQ, RZ. Another example is the factorization of a function as the composition of other functions having certain properties; for example, every function can be viewed as the composition of a surjective function with an injective function. This situation is generalized by factorization systems. algebra, math, quadratic, polynomial, factoring, factorization, trinomial, 9th, class, lahore, pakistan, ptbb, urdu, school, lesson, mathematics, 9th class mathematics, 9th class mathematics notes, 9th class mathematics solution, 9th class mathematics book, 9th class mathematics, 9th class mathematics paper 2017, 9th class mathematics notes, 9th class mathematics formula, 9th class mathematics solution, 9th class mathematics paper, 9th class mathematics key book, 9th class mathematics guide -~-~~-~~~-~~-~- Please watch: "Theory of Quadratic Equations 10th Maths Ex No 2 .7 Complete Solution" https://www.youtube.com/watch?v=0UP-z-hsaxY -~-~~-~~~-~~-~-

I don't leave any currency (crypto or fiat) in an exchange for longer than 15 minutes. I use these cryptocurrencies to pay my bills, so I transact very often. So far, I've only ever lost small amounts of bitcoin through stupid mistakes. 1. Don't leave your money on exchanges longer than you have to. If you day-trade, make sure you understand the risk that entails. 2. Organise a tiered storage system of hot and cold wallets, factoring in the amount of bitcoin you're storing, how you plan to use it (soon or not for a long time), and what security risks you're willing to take with each tier. 3. Use cold storage (i.e. paper wallets) for large amounts or for bitcoins you don't plan on using for a longer period of time. 4. Use hardware wallets that are PIN or password-protected 5. Use multi-signature multi-party or multi-factor wallets for carrying out your weekly business transactions. 6. Use hot wallets (ex. mobile wallets) for petty cash, or if you are the Oprah of cryptocurrency.

How Whales Trade Altcoins - A Whale’s Cryptocurrency Trading Philosophy
 
01:12
Altcoin Traders who hold massive amounts (many times large portions/majority portions of a coins overall supply) have the ability to reap huge profits trading and place enormous influence on an altcoins price and trend. Whales are highly calculative. They refrain from small time trades or trading the latest hyped coin on social media. Whales are patient. Extremely so. They may spend months or even years slowly accumulating (known as position building) a coin by buying very small amounts day in and day out as to not draw attention or spike the cryptocurrency’s price or volume. Slowly, they amasse a huge supply of the coins overall circulation. They diversify their supply across dozens or hundreds of wallets and hold coins in exchanges under multiple accounts to appear as “many traders” vs just one. When they pump their coin after the long accumulation period, they plan their pump meticulously. This includes: - Timing and execution planning factoring overall market sentiment and activity. - Using a small test pump, where they guage resistence and downward pressure in the specific market they are working in. - The final pump is not a short lived event, typically a true whale will time his pump to last days if not weeks. A sharp one or two day pump signals to other traders a crash is looming. - Slowly they continually push the price upwards and also downwards along the way. They have considerable positions on both the buy and sell side on all exchanges in which the altcoin is traded. - Many of the trades which contribute to a huge surge in volume are trades where they are simply buying and selling to themselves. With low trading fees, this is simply a cost of doing business. - All along the way, oblivious traders are buying into the pump, buying coins at prices that are 100x or even 1000s of times higher than what the whale payed for the coin during their accumulation period. - Because they are selling of only a small portion of their supply to new traders jumping in on the action, they retain control, and their supply, while selling off small chunks at huge profit margins. - Example: If a whale was able to accumulate and build their position averaging in at a price of 0.00000005 BTC, and now 2 years later, have pushed the price slowly over a 2-6 month period to 0.00000500 price point, any coins they sell are at 10000% Profit. This is their profit margin before the pump even starts. Once their pump begins, it can last months to show strong buy support and market strength. During this phase they will whats known as 10x the coin. Taking it from 500 Satoshis to 5000 or more Satoshis. Remember, the price they averaged in at was 5 Satoshis. The order book on the sell side is painted all the way up the tape with their sell positions. As they apply buy pressure by placing large orders on the buy side to show strong support, they will at the same time be actively buying their own positions between multiple accounts on the same exchange, all the while they move up their large buy walls, pushing the price up and up. Traders begin to jump in on the action. Buying in to even just a small fraction of the Whale’s overall position. At the peak of the pump the Whale may be making 100,000% gains on any sale. At these margins, Given a Coin with a 100,000,000 total supply, a Whale may hold 30,000,000 of those coins. Many times they hold stakes of 50% or higher. By selling at gains of 100,000%, the whale need only to sell off 1/1000th of their investment at the pumps relative trading high to break even. A True Crypto Whale is highly patient. They plan meticulously. They wait. And then they Bet it All. Follow on Twitter @Stratobitz On Bitcointalk @ Stratobitz Email: [email protected]

For example, the number 15 factors into primes as 3 × 5, and the polynomial x2 − 4 factors as (x − 2)(x + 2). In all cases, a product of simpler objects is obtained. The aim of factoring is usually to reduce something to “basic building blocks”, such as numbers to prime numbers, or polynomials to irreducible polynomials. Factoring integers is covered by the fundamental theorem of arithmetic and factoring polynomials by the fundamental theorem of algebra. Viète's formulas relate the coefficients of a polynomial to its roots. The opposite of polynomial factorization is expansion, the multiplying together of polynomial factors to an “expanded” polynomial, written as just a sum of terms. Integer factorization for large integers appears to be a difficult problem. There is no known method to carry it out quickly. Its complexity is the basis of the assumed security of some public key cryptography algorithms, such as RSA. A matrix can also be factorized into a product of matrices of special types, for an application in which that form is convenient. One major example of this uses an orthogonal or unitary matrix, and a triangular matrix. There are different types: QR decomposition, LQ, QL, RQ, RZ. Another example is the factorization of a function as the composition of other functions having certain properties; for example, every function can be viewed as the composition of a surjective function with an injective function.

Fermat's primality test

The algorithm is polynomial in the size of the input and it works in O(k polylog(p)) where k is the test accuracy parameter and p is the candidate being tested. Because Fermat's algorithm uses randomness, it is a probabilistic algorithm. Fermat's test is a flawed algorithm because Carmichael numbers are composite numbers that the test thinks are prime. Polynomial-time primality testing has many applications in cryptography such as key generation. If you liked this video, please thumbs up and subscribe. This is one of my first videos.

ICO Review: PayPie (PPP) - Credit Assessment on Blockchain Accounting
 
08:56
PayPie aims to bring transparency to the financial markets by introducing blockchain accounting. Full report by Crush Crypto: https://crushcrypto.com/analysis-of-paypie/ Download the free ICO Guide which contains 6 simple steps for analyzing any ICOs to find the winning projects: https://crushcrypto.com/youtube/ Note: This is not a paid review. We do not offer promotional or advertising services. Our content is based on our own research, analysis and personal opinion. _______________________________________ What does the company/project do? PayPie aims to bring trust and transparency to the financial markets by introducing credit risk assessment based on blockchain accounting catering to small and medium sized enterprises (SMEs). All the journal entries entered on the PayPie platform will be time-stamped on the blockchain, providing immutability of data. By analyzing financial data based on information stored on PayPie, a credit score can be generated for each business based on information such as liquidity ratio, working capital, profitability, book value, etc. By using up-to-date data on PayPie, PayPie’s goal is to be able to provide better credit assessments than banks. PayPie is also going to create an invoice financing marketplace where lenders can provide liquidity to SMEs based on their credit score as assessed by PayPie. All internal payments will be managed using ERC20 compatible stable “Pie Coins” that are exchangeable for fiat and pegged 1:1 against major currencies to avoid exposure to fluctuations in the prices of cryptocurrencies. _______________________________________ What are the tokens used for and how can token holders make money? PPP token is a utility token which provides access to the PayPie platform for certain transactions and services. Each PPP token grants the holder the right to access certain services including the purchase of invoices and access to credit histories of businesses. Lenders will require PPP tokens to access the PayPie platform, and tokens can be used to buy discounted invoices, credit scoring data and real-time financial data of a business. As PPP tokens are used to perform different actions on the PayPie platform, the more usage PayPie platform has, the more valuable PPP tokens should be. _______________________________________ Opportunities - The problem that PayPie is tackling is large. Many SMEs struggle to obtain financing from banks. It would really help the SMEs if they could obtain easier financing because of technology advancement. - Network effect is present. The more companies use the PayPie platform, the more valuable the platform is. _______________________________________ Concerns - PayPie is a white paper project with a lot of promises in many different areas – we believe they are trying to do too many things at the same time. - ​​​​​Automatic credit risk assessment is not easy – a lot of factors depend on the SME’s industry, geography location, management capacity, macroeconomic environment, etc. Asset-light industries have a very different set of financials from asset-heavy industries. We believe that in many cases, judgement is required. Therefore, the “100% accurate risk analysis goal” is virtually impossible to reach. - In the white paper, it is stated that “building strong partnerships with major accounting and ERP systems is a major aim of the overall marketing strategy.” As SlickPie, the team behind PayPie, competes with accounting software giants like Quickbooks and Xero, PayPie may have a difficult time collaborating with SlickPie’s competitors. - PayPie's idea works better when everything is settled in cash. However, in accounting, there are a lot of instances where transactions amount and timing are not clear cut (for example, stock options, accrual accounting, valuation adjustments, etc.) In those cases, judgment may be required and PayPie’s idea of trustless accounting will not work. - The roadmap is vague and the white paper lacks technical details, which makes it hard for the team to prove they have the technical knowledge to successfully work on this complex project. - The core members of the team are working on SlickPie and PayPie at the same time. It is unclear how they will allocate their time between the two ventures. _______________________________________ Disclaimer The information in this video is for educational purposes only and is not investment advice.

Bitcoin Q&A: Adoption of disruptive technology
 
06:35
What are the barriers to adopting cryptocurrencies, and what will be the most popular use cases for them in the next five to ten years? Science fiction didn't quite anticipate the evolution of computer technology. What you want is not always what will need. Disruptive technology breaks down previously existing categories and create new ones that didn't exist before. Bitcoin is changing our conception of what a payment is and can do. What is the "streaming money" use case? There will be a transition changes the time dimension of money, from batches to flows. These questions are from the Seattle 'Internet of Money' tour event, which took place on November 10th, 2018.

#130 - Eric Falkenstein - I Think in the Long Run (Cryptocurrencies) Are Going to Work
 
50:51
To see links or read the transcript of the episode, visit us at: https://mebfaber.com/2018/11/21/episode-130-eric-falkenstein-i-think-in-the-long-run-cryptocurrencies-are-going-to-work/ In Episode 130, we welcome Eric Falkenstein. The show starts with Meb and Eric discussing ice fishing in Minnesota (where Eric is currently located). But then Meb asks for Eric’s origin story. Eric tells us about being a teacher’s assistant for Hyman Minsky, wanting to be a macro economist, the turn that pushed him toward investing, and a well-timed put option that made him a boatload in the ’87 crash. Next, the conversation turns toward Eric’s interest in low volatility. He tells us about being one of the first people to study low-vol. He was early, and the broader investing community wasn’t ready for the findings. People dismissed the suggestion that high volatility stocks (with high risk) didn’t outperform low vol stocks. Eric tells us that given all this, “low vol” wasn’t enough of a selling point – you had to layer on another factor just to get people to pay attention. Meb asks about the main value proposition of low-vol. It is a smoother ride? Better returns? And why does this factor persist? Eric’s answer touches on CAPM, high beta, low beta, risk, various premiums, high flying stocks, and alpha discovery. This bleeds into a conversation about factoring timing relative to valuations. Eric tells us he tried factor timing, but didn’t find it to be too helpful out of sample. The conversation bounces around a bit, with the guys touching on Meb’s paper, “A Quantitative Approach to Asset Allocation,” bonds and how the US is flirting with the top bucket of bond yields, whether low vol translates to global markets and different asset classes, and Eric’s take on risk parity. After that, the guys turn to crypto. Despite the current pullback, Eric believes “in the long run, it’s going to work.” He believes that crypto will eventually replace Dollars as people will want an alternative to fiat currency, something not susceptible to manipulation by politicians. He tells us that he sees a tipping point coming. There’s plenty more in this episode – Eric’s books, pithy quotes and maxims, how people often think about the specific investment they want, but not the “plumbing” such as the bid/ask spread of that investment, the volume, and so on… And as always, Eric’s most memorable trade. Get all the details in Episode 130.

Familiarize yourself with the crucial building-block concept of divisibility. Learning divisibility will make so many math concepts easy, from fractions and rations, to proportions and percents. It's going to make factoring and other algebraic concepts so much clearer. Can you tell divisibility is one of our favorite subjects here at Light & Salt Learning? The lesson is the second in a series that corresponds to The McGraw Hill GED Math Book Chapter 1 Exercise 4. Practice what you've learned at www.quizlet.com, Kate's GED Math Class.
Factoring by Splitting the Middle Term for GCE and IGCSE (O Level Students)

For example, the number 15 factors into primes as 3 × 5, and the polynomial x2 − 4 factors as (x − 2)(x + 2). In all cases, a product of simpler objects is obtained. The aim of factoring is usually to reduce something to “basic building blocks”, such as numbers to prime numbers, or polynomials to irreducible polynomials. Factoring integers is covered by the fundamental theorem of arithmetic and factoring polynomials by the fundamental theorem of algebra. Viète's formulas relate the coefficients of a polynomial to its roots. The opposite of polynomial factorization is expansion, the multiplying together of polynomial factors to an “expanded” polynomial, written as just a sum of terms. Integer factorization for large integers appears to be a difficult problem. There is no known method to carry it out quickly. Its complexity is the basis of the assumed security of some public key cryptography algorithms, such as RSA. A matrix can also be factorized into a product of matrices of special types, for an application in which that form is convenient. One major example of this uses an orthogonal or unitary matrix, and a triangular matrix. There are different types: QR decomposition, LQ, QL, RQ, RZ. Another example is the factorization of a function as the composition of other functions having certain properties; for example, every function can be viewed as the composition of a surjective function with an injective function. This situation is generalized by factorization systems. algebra, math, quadratic, polynomial, factoring, factorization, trinomial, 9th, class, lahore, pakistan, ptbb, urdu, school, lesson, mathematics, 9th class mathematics, 9th class mathematics notes, 9th class mathematics solution, 9th class mathematics book, 9th class mathematics, 9th class mathematics paper 2017, 9th class mathematics notes, 9th class mathematics formula, 9th class mathematics solution, 9th class mathematics paper, 9th class mathematics key book, 9th class mathematics guide -~-~~-~~~-~~-~- Please watch: "Theory of Quadratic Equations 10th Maths Ex No 2 .7 Complete Solution" https://www.youtube.com/watch?v=0UP-z-hsaxY -~-~~-~~~-~~-~-
