RSA Algorithm is the example for Public Key Encryption algorithm. Here we are supposed to find two keys 1) Public Key which is used at encryption 2) Private Key which is used at decryption step 1: Select two large Primes P , Q Step 2: Calculate n=P*Q & O(n) = (P-1)*(Q-1) Step 3: Assume e and d (Public and Private Key). Step 4: Encrypt the Plain Text using Public Key e. Step 5: Decrypt the Cipher Text using Private Key d.

Once you know how to solve diophantine equations with a single variable, the next step in complexity is to consider equations with two variables. The simplest such equations are linear and take the form ax+by=c. Before we solve this equation generally, we need a preliminary result. We show that you can solve the equation ax+by=GCD(a,b) by performing the Euclidean algorithm, and then reverse-substituting to arrive at a single solution.

For this HackerRank problem, we use the Euclid's algorithm to find the GCD (Greatest Common Divisor) of two numbers. The problem is based on the scene in Die Hard 3.0, where John McClane has to solve a mathematical problem based on this to save the city! The GCD of two given numbers is defined as the largest possible number which divides both the numbers with no remainder. The GCD of a number is also sometimes called Highest Common Factor. We take sample test cases to see how this problem can be solved, and then move to a proof for a general case. Make sure to check out the other two videos on the proof of the algorithm (https://youtu.be/B5HKW99AvV0) and the code (https://youtu.be/80pOI0_BXyk)!

The Euclid's algorithm is widely used to find the GCD, short for Greatest Common Factor, of numbers. It uses interesting mathematical properties of division and remainders to find the answer. Here we prove the GCD algorithm once again to bring clarity to Euclid's method of dividing the larger number by the smaller one and setting the new parameters to the smaller and remaining number.

There are three variations shown here: 1) Recursive GCD 2) Iterative GCD 3) Binary GCD The GCD of two given numbers is defined as the largest possible number which divides both the numbers with no remainder.

Python is an interpreted text based general purpose programming language, which is a key requisite of the 7-10 Digital Technologies Curriculum. Python is also the only professional programming language that was designed with beginners in mind, it is intuitive and easy to use What are the student outcomes? Students learn about core concepts of programming: branching, iteration and functions. They apply these to create four applications which perform the following: Simulation of an intelligent conversation User Authentication using passwords and/or secret questions A game where user guesses a number and the program informs the user of his accuracy over time A program that encrypts and decrypts messages using the Caesar Cypher What is the educational approach of the course? The course explicitly teaches the concepts such as loops or functions, performing several examples in the interactive shell. Then these concepts are employed to create a computer program these programs progress in their level of difficulty, eventually performing complex tasks like encryption Beyond the concepts and applications students will also learn the following skills: Creating algorithms which can be represented in the form of flowcharts, which are in turn easy to translate to code. Building programs in separate stages each of which can be tested Getting insight and understanding from error messages -~-~~-~~~-~~-~- Latest and Best Arduino Playlist in Collaboratio with DFRobot: https://www.youtube.com/playlist?list=PL_92WMXSLe_86NTWf0nchm-EmQIwccEye -~-~~-~~~-~~-~-

The ``cryptography`` library emerged in 2014 with the goal of becoming Python's "cryptographic standard library". It is designed to be easy to use but flexible, exposing a *recipes* layer for common use cases, and a *hazmat* layer that provides crypto primitives but demands users know what they're doing in order to use them properly. This talk will explain the motivations and goals of the ``cryptography`` library, take a tour of its features and discuss its implementation. ``cryptography`` will be compared to some other popular and emerging crypto libraries. Finally, we will examine some real-world use of the library. Audience members should have a passing familiarity with cryptography (e.g. know the differences between hashing and encryption, or public key and private key crypto) to get the most out of this talk. PyCon Australia is the national conference for users of the Python Programming Language. In 2015, we're heading to Brisbane to bring together students, enthusiasts, and professionals with a love of Python from around Australia, and all around the World.

The Sieve of Eratosthenes and trial division are the simplest way of determining whether a number is a prime, a primality test. This is an exponential way of checking for primality, as the complexity is Ω(sqrt(n)). Primality testing has many applications including cryptography.

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.

В этом ролике мы разберемся, в чем заключается Гипотеза Римана — одна из семи математических проблем тысячелетия! ЗАДАЧНИК КО ВСЕМ РОЛИКАМ: https://vk.com/wall-135395111_8104 МОИ КУРСЫ: https://vk.com/market-135395111 УСКОРИТЬ ПРОЦЕСС СОЗДАНИЯ НОВОГО ВИДЕО: http://www.donationalerts.ru/r/wildmathing VK: https://vk.com/wildmathing Кто-то ждал нового ролика с высшей математикой, кто-то — с занимательной, кто-то жаждет материала посложней, кто-то — полегче . Уверен, этот ролик будет полезен и интересен всем: от элементарной математики мы дойдем до открытой проблемы тысячелетия — гипотезы Римана! Уровень 1. Простые числа — 0:05 Уровень 2. ТРПЧ — 1:30 Уровень 3. 1859 — 3:09 Уровень 4. Гипотеза Римана — 4:32 Уровень 5. Дзета-функция Римана — 5:17 Уровень 6. Смекалистый друг —6:51 Уровень 7. Аналитическое продолжение — 7:39 UPD. На 2:23 гипотеза Гаусса и Лежандра, конечно же, сразу состояла в асимптотическом поведении функции π(x)~x/lnx (x → oo). То, что равенство не выполнено очевидно для того же примера из видео для x=100. Фразу на 3:37 тоже следует подправить. Конечно же, речь идет о том, что n пробегает натуральные числа, а сигма суммирует все обратные числа к n^s. РЕКОМЕНДУЕМАЯ ЛИТЕРАТУРА И ПОЛЕЗНЫЕ РЕСУРСЫ 1.

An animated attempt of explaining the Playfair cipher. This tutorial includes rules of the cipher followed by an example to clear things up. This was a part of my final year project to create a learning aid. I decided to upload this so the animation won't go to waste. All feedbacks welcome. Special thanks to Olivia Beck for creating the background image

When learning about groups, it’s helpful to look at group multiplication tables. Sometimes called Cayley Tables, these tell you everything you need to know to analyze and work with small groups. It’s even possible to use these tables to systematically find all groups of small order!
