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...

Hello Dosto
Aaj hum baat karenge cryptography ke bare me ki ye kya hota hai aur iska itemaal kaise aur kaha hota hai. iska sambandh kisi bhi data ya message ko safely pohchane se hota hai aur uski security badhayi jati hai taaki bich me koi an-adhikarik tarike se usko access na kar paye. aasha karta hoo apko ye video pasand ayegi agar aapko ye video achhi lage to isse like kare aur apne dosto ke sath share kare aur abhi tak aapne mera channel subscribe nahi kia hai to jarur is channel ko subscribe kare.

With recent high-profile security decryption cases, encryption is more important than ever. Much of your browser usage and your smartphone data is encrypted. But what does that process actually entail? And when computers get smarter and faster due to advances in quantum physics, how will encryption keep up?

Regarding the keys used for encryption:
x, y prime
Encode key E shares no factors with (x-1)(y-1)
Decode key is D with E*D - 1 a multiple of (x-1)(y-1)

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 World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.

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.”

Learn Public Key Cryptography in just 18 Minutes - Cryptography Tutorial

In this Cryptography Tutorial, I teach you Public Key cryptography basics. Specifically I’m going to explain to you how the cryptography works, that allows you to do online shopping. We are so used to online shopping, a.k.a. e-commerce, that we take it for granted. But e-commerce would not be possible at all without public key cryptography. Not only will I explained to you the details of public-key cryptography and how that makes e-commerce possible, but I’m going to explain it in 15 minutes, and explain it without math, by using the Blackbox model.

IMHO, cryptography basics should not include math. Cryptography explained with math simply muddies the waters to those without extensive math background.

Let’s start by taking a brief look at Classic cryptography, which is been around for thousands of years. Classic cryptography is also called secret key cryptography or Symmetric cryptography.

A cipher is some sort of a mathematical algorithm that we use to scramble text. In the blackbox model the cipher itself is the blackbox into which we input plaintext and the...

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).
