Cryptography: Crash Course Computer Science #33
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.

Keeping Secrets: Cryptography In A Connected World
Josh Zepps, Simon Singh, Orr Dunkelman, Tal Rabin, and Brian Snow discuss how, since the earliest days of communication, clever minds have devised methods for enciphering messages to shield them from prying eyes. Today, cryptography has moved beyond the realm of dilettantes and soldiers to become a sophisticated scientific art—combining mathematics, physics, computer science, and electrical engineering. It not only protects messages, but it also safeguards our privacy. From email to banking transactions, modern cryptography is used everywhere. But does it really protect us? What took place was a discussion of cryptography’s far-reaching influence throughout history from Julius Caesar’s reign to Julian Assange’s WikiLeaks, and the ways in which it—and our privacy—are constantly under assault today as threats lurk behind IP addresses, computational power increases, and our secrets move online.

The Science of Secrecy from Ancient Egypt to Quantum Cryptography (1999)
Simon Lehna Singh MBE (born 19 September 1964) is a British popular science author whose works largely contain a strong mathematical element. His written works include Fermat's Last Theorem (in the United States titled Fermat's Enigma: The Epic Quest to Solve the World's Greatest Mathematical Problem),[2][3] The Code Book[4] (about cryptography and its history), Big Bang[5] (about the Big Bang theory and the origins of the universe), Trick or Treatment? Alternative Medicine on Trial[6] (about complementary and alternative medicine, co-written by Edzard Ernst) and The Simpsons and Their Mathematical Secrets (about mathematical ideas and theorems hidden in episodes of The Simpsons and Futurama).[7] In 2012 Singh founded the Good Thinking Society.[8] Singh has also produced documentaries and works for television to accompany his books, is a trustee of NESTA, the National Museum of Science and Industry and co-founded the Undergraduate Ambassadors Scheme. Singh's parents emigrated from Punjab, India to Britain in 1950. He is the youngest of three brothers, his eldest brother being Tom Singh, the founder of the UK New Look chain of stores. Singh grew up in Wellington, Somerset, attending Wellington School, and went on to Imperial College London, where he studied physics. He was active in the student union, becoming President of the Royal College of Science Union.[9] Later he completed a PhD degree in particle physics at Emmanuel College, Cambridge and at CERN, Geneva. In 1983, he was part of the UA2 experiment in CERN.[11] In 1987, Singh taught science at The Doon School, the independent all-boys' boarding school in India.[12] In 1990 Singh returned to England and joined the BBC's Science and Features Department, where he was a producer and director working on programmes such as Tomorrow's World and Horizon. Singh was introduced to Richard Wiseman through their collaboration onTomorrow's World. At Wiseman's suggestion, Singh directed a segment about politicians lying in different mediums, and getting the public's opinion on if the person was lying or not. After attending some of Wiseman's lectures, Singh came up with the idea to create a show together, and Theatre of Science was born. It was a way to deliver science to normal people in an entertaining manner. Richard Wiseman has influenced Singh in such a way that Singh states: My writing initially was about pure science but a lot of my research now has been inspired by his desire to debunk things such as the paranormal – we both hate psychics, mediums, pseudoscience in general.[13] Singh directed his BAFTA award-winning documentary about the world's most notorious mathematical problem entitled "Fermat's Last Theorem" in 1996. The film was memorable for its opening shot of a middle-aged mathematician, Andrew Wiles, holding back tears as he recalled the moment when he finally realised how to resolve the fundamental error in his proof of Fermat's Last Theorem. The documentary was originally transmitted in October 1997 as an edition of the BBC Horizon series. It was also aired in America as part of the NOVA series. The Proof, as it was re-titled, was nominated for an Emmy Award. The story of this celebrated mathematical problem was also the subject of Singh's first book, Fermat's last theorem. In 1997, he began working on his second book, The Code Book, a history of codes and codebreaking. As well as explaining the science of codes and describing the impact of cryptography on history, the book also contends that cryptography is more important today than ever before. The Code Book has resulted in a return to television for him. He presented The Science of Secrecy, a five-part series for Channel 4. The stories in the series range from the cipher that sealed the fate of Mary, Queen of Scots, to the coded Zimmermann Telegram that changed the course of the First World War. Other programmes discuss how two great 19th century geniuses raced to decipher Egyptian hieroglyphs and how modern encryption can guarantee privacy on the Internet. https://en.wikipedia.org/wiki/Simon_Singh Image: Sam Hughes [CC BY 2.0 (http://creativecommons.org/licenses/by/2.0)], via Wikimedia Commons

Stanford Seminar - The Evolution of Public Key Cryptography
EE380: Computer Systems Colloquium Seminar The Evolution of Public Key Cryptography Speaker: Martin Hellman, Stanford EE (Emeritus) While public key cryptography is seen as revolutionary, after this talk you might wonder why it took Whit Diffie, Ralph Merkle and Hellman so long to discover it. This talk also highlights the contributions of some unsung (or "under-sung") heroes: Ralph Merkle, John Gill, Stephen Pohlig, Richard Schroeppel, Loren Kohnfelder, and researchers at GCHQ (Ellis, Cocks, and Williamson). Resources and Reading Materials M. E. Hellman, Cybersecurity, Nuclear Security, Alan Turing, and Illogical Logic (http://www-ee.stanford.edu/ %7Ehellman/publications/77.pdf), Communications of the ACM, Vol. 60, No. 12, pp. 52-59, December 2017. This is a written version of Martin Hellman's ACM Turing Lecture (https://www.youtube.com/watch?v=I132wSwAI3o) and was accompanied by a short (6 minute) video (https://vimeo.com/241030842). Other materials and hard to find references can be found on Martin Hellman's Stanford website, http://www-ee.stanford.edu/~hellman/ . About the Speaker: Martin E. Hellman is Professor Emeritus of Electrical Engineering at Stanford University and is affiliated with the university's Center for International Security and Cooperation (CISAC). His recent technical work has focused on bringing a risk informed framework to a potential failure of nuclear deterrence and then using that approach to find surprising ways to reduce the risk. His earlier work included co- inventing public key cryptography, the technology that underlies the secure portion of the Internet. His many honors include election to the National Academy of Engineering and receiving (jointly with his colleague Whit Diffie) the million dollar ACM Turing Award, the top prize in computer science. His most recent project is a book, jointly written with his wife of fifty years, "A New Map for Relationships: Creating True Love at Home & Peace on the Planet," that provides a "unified field theory" of peace by illuminating the connections between nuclear war, conventional war, interpersonal war, and war within our own psyches.

History - Secrets Exposed - Cryptology - WWII Code breaking
From VOA Learning English, this is EXPLORATIONS in Special English. I'm Jeri Watson. And I'm Jim Tedder. Today we visit a small museum in the American state of Maryland. It is called the National Cryptologic Museum. There you will find information that was once secret. The National Cryptologic Museum is on Fort George G. Meade, a military base near Washington, DC. It tells the story of cryptology and the men and women who have worked in this unusual profession. The word cryptology comes from the Greek "kryptos logos." It means "hidden word." Cryptology is writing or communicating in ways designed to hide the meaning of your words. The museum has many examples of equipment that was once used to make information secret. It also has equipment that was developed to read secret messages. The method of hiding exact meanings is called coding. People have used secret codes throughout history to protect important information. One display at the museum explains American attempts to read Japanese military information during World War Two. Japan's Navy used special machines to change its written information into secret codes. This coded information was then sent by radio to navy ships and military bases. The information included secret military plans and orders. The leaders of the Japanese Navy believed no one could read or understand the secret codes. They were wrong. Americans were working very hard to learn the Japanese code. The United States urgently needed to break the code to learn what Japan was planning. In 1940, an American woman named Genevieve Grotjan found some information being repeated in Japanese coded messages. At the time, she was a civilian working for the government in Washington, DC. Her discovery helped the United States understand secret Japanese diplomatic messages. After the United States understood the code, it was possible to study messages from the Japanese ambassador to Germany and to his supervisors in Japan. After the attack on Pearl Harbor, an American Naval officer named Joseph Rochefort struggled to understand the Japanese navy code. He worked on the American base at Pearl Harbor. It was early in 1942. The American naval commander in the Pacific Ocean was Chester Nimitz. His forces were much smaller than the Japanese Naval forces. And the Japanese had been winning many victories. Joseph Rochefort had worked for several months to read the secret Japanese Naval code called JN-25. If he could understand enough of the code, he would be able to give Admiral Nimitz very valuable information. The admiral could use this information to plan for battle. By the early part of the year, Mr. Rochefort and the men who worked with him could read a little less than 20 percent of the Japanese JN-25 code. Joseph Rochefort had the evidence he needed. "AF" was now known to be the island of Midway. He also told Admiral Nimitz the Japanese would attack Midway on June third. The admiral secretly moved his small force to an area near Midway and waited for the Japanese Navy. The battle that followed was a huge American victory. Experts now say the Battle of Midway was the beginning of the American victory in the Pacific. That victory was possible because Joseph Rochefort learned to read enough of the Japanese code to discover the meaning of the letters "AF." One American code has never been broken. Perhaps it never will. It was used in the Pacific during World War Two. For many years the government would not discuss this secret code. Listen for a moment to this very unusual code. Then you may understand why the Japanese military forces were never able to understand any of it. The code is in the voice of a Native American. The man you just heard is singing a simple song in the Navajo language. Very few people outside the Navajo nation are able to speak any of their very difficult language. At the beginning of World War Two, the United States Marine Corps asked members of the Navajo tribe to train as Code Talkers. The Cryptologic Museum says the Marine Corps Code Talkers could take a sentence in English and change it into their language in about 20 seconds. A code machine needed about 30 minutes to do the same work. The Navajo Code Talkers took part in every battle the Marines entered in the Pacific during World War Two. The Japanese were very skilled at breaking codes. But they were never able to understand any of what they called "The Marine Code." Perhaps the most famous is a World War Two German code machine called the Enigma. The word "enigma" means a puzzle or a problem that is difficult to solve. The German military used the Enigma machine to communicate orders and plans. The United States, Britain, and the government of Poland cooperated in learning to read information sent by the Enigma. It took thousands of people and cost millions of dollars to read the Enigma information. This is a VOA product and is in the public domain

Why cryptography and information Security course
www.hiteshChoudhary.com www.newdemy.com Cryptography What is cryptography? Cryptography (or cryptology; from Greek κρυπτός, "hidden, secret"; and γράφειν, graphein, "writing", or -λογία, -logia, "study", respectively) is the practice and study of techniques for secure communication in the presence of third parties (called adversaries).More generally, it is about constructing and analyzing protocols that overcome the influence of adversaries and which are related to various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation. Modern cryptography intersects the disciplines of mathematics, computer science, and electrical engineering. Applications of cryptography include ATM cards, computer passwords, and electronic commerce. Yeah, I know that you have read the above lines many times. These are perfectly true jargons. It’s just something like our brain is made of 80% of water, technically true but it doesn’t explain things much. When I tried to study Cryptography, it was tough. When anyone wants to learn HTML, he can find a lots of resources on internet but when things come to Cryptography you need to buy a lots of books and watch a lots of youtube videos which contains an annoying background music. A lots of blog are also helpful but all are fragmented. So, I decided that it is a good time to put Cryptography course. The course will be beginners friendly and will teach you a lot of things about Information Security. This series is not meant for 2 communities of people over the internet. 1. Not bothered about Computer Security 2. True Computer professional [Advanced programmers and crypto masters] The category one does not fit into any computer security course as information security comes at very last in their priority list. Hence, most of the time they are the practice playgrounds for most of the hackers. The category two has moved into the immense knowledge of information security. And they know all the stuff or most of the present stuff about it. So, they will feel bore in this series because they are the inventor of most of the stuff. Rest of the people are going to love this cryptography online video series. The candidates for which I am looking to take this cryptography course are: 1. University Students 2. Hackers a. Fretos : The freshers b. Practos: The practical ones University Students will be interested in this course as most of the Universities have curriculum of Cryptography. The second category is of hackers but I have divided them into 2 major categories. First one is Fretos, these are fresher in information security and are trying to learn stuff. It is a good time for them to start this series because you will understand terms like MITM, RSA, MD5 and DSA. Second category is hackers who have learned most of the things practically. Personally, I am very impressed that you have gained so much of knowledge. You might have knowledge about hacking into various accounts and systems or even knowledge of creating exploits. But ask a simple question to yourself, you are a pro in hacking skills but have no idea about RSA or Block ciphers. You know to break WEP in wireless but no idea of WEP encryption or cryptic flaw in algorithm. I hope that you have got my point. So, let’s get started.

Albrecht Petzoldt - The Cubic Simple Matrix Encryption Scheme
Albrecht Petzoldt of TU Darmstadt presented a talk titled: The cubic simple matrix encryption scheme at the 2014 PQCrypto conference in October, 2014. Abstract: In this paper, we propose an improved version of the Simple Matrix encryption scheme of PQCrypto2013. The main goal of our construction is to build a system with even stronger security claims. By using square matrices with random quadratic polynomials, we can claim that breaking the system using algebraic attacks is at least as hard as solving a set of random quadratic equations. Furthermore, due to the use of random polynomials in the matrix A, Rank attacks against our scheme are not feasible.
