Stanford Seminar - The Evolution of Public Key Cryptography
 
01:14:30
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.

Cryptography: Crash Course Computer Science #33
 
12:33
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. Our friends over at Computerphile have a great video on the topic: https://www.youtube.com/watch?v=mYtvjijATa4 Produced in collaboration with PBS Digital Studios: http://youtube.com/pbsdigitalstudios Want to know more about Carrie Anne? https://about.me/carrieannephilbin The Latest from PBS Digital Studios: https://www.youtube.com/playlist?list=PL1mtdjDVOoOqJzeaJAV15Tq0tZ1vKj7ZV Want to find Crash Course elsewhere on the internet?

Dan Boneh: What is the future of cryptography?
 
04:53
Dan Boneh talks about how he first became interested in encryption and the future of Internet security. Boneh is a Professor of Computer Science and of Electrical Engineering at Stanford and an expert in encryption and cyber security. “I was fascinated with computers from a very young age. So, I just fell in love with these things that you can program them and tell them what to do and they just do it without arguing with you. It also became very clear that they're gonna hold a lot personal data about everyone, and it's kinda vital to protect that information somehow.”

In this course you will learn the inner workings of cryptographic systems and how to correctly use them in real-world applications. The course begins with a detailed discussion of how two parties who have a shared secret key can communicate securely when a powerful adversary eavesdrops and tampers with traffic. We will examine many deployed protocols and analyze mistakes in existing systems. The second half of the course discusses public-key techniques that let two parties generate a shared secret key. Throughout the course participants will be exposed to many exciting open problems in the field and work on fun (optional) programming projects. In a second course (Crypto II) we will cover more advanced cryptographic tasks such as zero-knowledge, privacy mechanisms, and other forms of encryption.

In this episode, I talk with legend of cryptography, Whitfield Diffie. Whit was working on cryptography long before Bitcoin existed, building the foundations for which Bitcoin relies upon. We discuss his history, Bitcoin and his views on privacy.

Nick Szabo highlighted a number of these people in his Tweet: “Inventors of the most important technologies in Bitcoin: digital signatures and Merkle trees (Merkle), elliptic curve crypto (Koblitz), malicious-fault-tolerant consensus (Lamport), elliptic curve crypto (independent inventor: Miller).” Many others along the way have contributed to the success of Bitcoin, either through early work or attempts at created a digital currency, names such as Adam Back, David Chaum and Szabo himself. Whitfield Diffie sits alongside all of these people. His work on cryptography should not be forgotten in the history of Bitcoin and I had the pleasure of sitting down with him to discuss this, how he was introduced to Bitcoin and other such topics as privacy and security. ***** 00.03.09: Intro and welcome 00.03.48: The father of cryptography 00.04.46: Cryptography third wave with cryptocurrencies 00.05.44: Whit’s back story 00.07.44: The journey to become a cryptographer 00.18.14: Understanding cryptography 00.25.16: Early thoughts of money with cryptography 00.28.12: The centralisation problem with digital currencies 00.30.51: Whit’s exposure to Bitcoin 00.36.19: Where we use cryptography 00.39.55: Privacy 00.43.29: Thoughts on the evolution of technology 00.47.10: Cryptography and world security 00.56.27: Quantum computing 00.59.14: Significant unsolved problems in cryptography

Introduction to Cryptography - I ===================== Materials (video, slides, english subtitles) from / Stanford Introduction to Cryptography Slides & Subtitle Link: http://www.mediafire.com/file/rr8pnxag9kpe3g7/Crypto-I.rar/file About this Course: Cryptography is an indispensable tool for protecting information in computer systems. In this course you will learn the inner workings of cryptographic systems and how to correctly use them in real-world applications. The course begins with a detailed discussion of how two parties who have a shared secret key can communicate securely when a powerful adversary eavesdrops and tampers with traffic. We will examine many deployed protocols and analyze mistakes in existing systems. The second half of the course discusses public-key techniques that let two parties generate a shared secret key. Throughout the course participants will be exposed to many exciting open problems in the field and work on fun (optional) programming projects. In a second course (Crypto II) we will cover more advanced cryptographic tasks such as zero-knowledge, privacy mechanisms, and other forms of encryption. SKILLS YOU WILL GAIN During the 66 Video in this Course: 1 - Cryptography, 2 - Cryptographic Attacks, 3 - Public-Key Cryptography, 4 - Symmetric-Key Algorithm,
