Symmetric keys are essential to encrypting messages. How can two people share the same key without someone else getting a hold of it? Upfront asymmetric encryption is one way, but another is Diffie-Hellman key exchange. This is part 3 in our Cryptography 101 series. Check out the playlist here for parts 1 & 2: https://www.youtube.com/watch?v=NOs34_-eREk&list=PLa6IE8XPP_gmVt-Q4ldHi56mYsBuOg2Qw Support us on Patreon at https://www.patreon.com/pbsinfinitese...

They’re fast and practically bulletproof… once two parties like Alice and Bob have a single shared key in hand. And that’s the challenge -- they can’t use symmetric key encryption to share the original symmetric key, so how do they get started?

Learn more advanced front-end and full-stack development at: https://www.fullstackacademy.com Elliptic Curve Cryptography (ECC) is a type of public key cryptography that relies on the math of both elliptic curves as well as number theory. This technique can be used to create smaller, faster, and more efficient cryptographic keys. In this Elliptic Curve Cryptography tutorial, we build off of the Diffie-Hellman encryption scheme and show how we can change the Diffie-Hellman procedure with elliptic curve equations.

A Framework for Universally Composable Diffie-Hellman Key Exchange Daniel Rausch (University of Stuttgart) Presented at the 2017 IEEE Symposium on Security & Privacy May 22–24, 2017 San Jose, CA http://www.ieee-security.org/TC/SP2017/ ABSTRACT The analysis of real-world protocols, in particular key exchange protocols and protocols building on these protocols, is a very complex, error-prone, and tedious task. Besides the complexity of the protocols itself, one important reason for this is that the security of the protocols has to be reduced to the security of the underlying cryptographic primitives for every protocol time and again. We would therefore like to get rid of reduction proofs for real-world key exchange protocols as much as possible and in many cases altogether, also for higher-level protocols which use the exchanged keys. So far some first steps have been taken in this direction. But existing work is still quite limited, and, for example, does not support Diffie-Hellman (DH) key exchange, a prevalent cryptographic primitive for real-world protocols. In this paper, building on work by Kusters and Thengerthal, we provide an ideal functionality in the universal composability setting which supports several common cryptographic primitives, including DH key exchange. This functionality helps to avoid reduction proofs in the analysis of real-world protocols and often eliminates them completely. We also propose a new general ideal key exchange functionality which allows higher-level protocols to use exchanged keys in an ideal way. As a proof of concept, we apply our framework to three practical DH key exchange protocols, namely ISO 9798-3, SIGMA, and OPTLS.

The Diffie-Hellman key exchange is used extensively in Internet communications today. Many web applications use this key exchange because it achieves Perfect Forward Secrecy (using ephemeral keys) which provides more security than other key exchange algorithms like RSA. In this video, John explains the Diffie-Hellman key exchange, and he walks through an example of the calculations used to make it all work. https://devcentral.f5.com/articles/lightboard-lessons-explaining-the-diffie-hellman-key-exchange-31674

How modern encryption systems can share secret keys without transmitting them. This means that even when powerful government agencies, criminals, competitors, or ISPs listen in on absolutely everything you do, your information can still be kept private, even if you need to communicate with a total stranger and have never made any prior arrangements for privacy. This is absolutely the clearest, most comprehensive explanation of the Diffie Hellman key exchange protocol ever done in video. After you watch this, you will understand Diffie Hellman cryptographic key exchange better than 99.999% of the human population, and you won't need math beyond the 4th grade level!

TURN ON ANNOTATIONS OR SUBTITLES TO MAXIMIZE YOUR VIEWING EXPERIENCE! Here is my application for the Science Ambassador Scholarship! My name is Olga Andreeva, and I am planning on majoring in computer science. Cryptography is what holds our world together: it prevents secret information like credit card and social security numbers from being released to the public, allowing people to do their business online securely without the fear of identity theft. It gives us a way to communicate around the world with confidence. For my topic, I picked the Diffie-Hellman key exchange, a way for two people to generate a private key that hackers can't access. I demonstrated this by mixing paint colors. Hope you enjoy :)

Earlier this year, we discovered that Diffie-Hellman key exchange – cornerstone of modern cryptography – is less secure in practice than the security community believed. In this talk, we’ll explain how the NSA is likely exploiting this weakness to allow it to decrypt connections to at least 20% of HTTPS websites, 25% of SSH servers, and 66% of IPsec VPNs. J.

Whitfield Diffe and Martin Hellman received the 2015 ACM A.M. Turing Award for critical contributions to modern cryptography. The ability for two parties to use encryption to communicate privately over an otherwise insecure channel is fundamental for billions of people around the world. On a daily basis, individuals establish secure online connections with banks, e-commerce sites, email servers and the cloud. Diffie and Hellman's groundbreaking 1976 paper, "New Directions in Cryptography," introduced the ideas of public-key cryptography and digital signatures, which are the foundation for most regularly-used security protocols on the Internet today. The Diffie-Hellman Protocol protects daily Internet communications and trillions of dollars in financial transactions.
