Symmetric Key Echange Problem - 1. Key exchange solution is not fool proof or is not practically possible. 2. This problem is called as key distribution or key exchange problem. 3. It is inherently linked with the symmetric key cryptography Diffie-Hellman Key Exchange/ Agreement Algorithm - 1. Two parties, can agree on a symmetric key using this technique. 2. This can then be used for encryption/ decryption. 3. This algorithm can be used only for key agreement, but not for encryption or decryption. 4. It is based on mathematical principles Diffie Hellman Algorithm Steps - 1. Firstly Alice and Bob mutually agree on 2 large prime numbers, n & g. These 2 numbers need not be kept secret. 2. Alice chooses another large random number x(private to her) and calculates A such that A = g^x mod n. 3. Alice sends this number A to Bob. 4. Bob independently chooses another large random number y(private to him) and calculates B such that B = g^y mod n. 5. Bob sends this number B to Alice. 6. Alice now computes her private key value K1 as: K1 = B^x mod n. 7. Bob computes his private key value K2 as: K2 = A^y mod n. 8.

Elliptic Curve Diffie Hellman


A short video I put together that describes the basics of the Elliptic Curve Diffie-Hellman protocol for key exchanges. There is an error at around 5:30 where I state that the point at infinity is the result of point-doubling a point whose X coordinate is zero. This is incorrect, it should be when the Y coordinate is zero. Also I state 'geographically' instead of 'geometrically'.

DHKE : Demo with mixing colors - part 1/2


We use a shared secret key in the symmetric encryption algorithm to encrypt and decrypt messages, but how to distribute the secret key between two parties? By email, snail mail, or a trusted courier? All these methods are slow, insecure, and impractical over the Internet, the insecure channel where most of our communications are to be encrypted. Diffie-Hellman Key Exchange (DHKE) protocol provides a radically new method of distributing cryptographic keys, that helped solve key distribution—a fundamental problem in cryptography. Today I will introduce DHKE and demonstrate how it works with mixing colors.

Discovery of Public Key Cryptography with Whitfield Diffie (2015 Turing Award)


2015 Turing Award recipient Whitfield Diffie tells the story of how he discovered public key cryptography and the Diffie-Hellman key exchange. Whit was first introduced to cryptography at school, but didn’t return to it until after the completion of his degree at MIT, when he was working as a researcher at the Stanford Artificial Intelligence Laboratory. He describes a chance meeting between his boss John McCarthy and Larry Roberts, where the issue of network security was first mentioned. When John returned to Stanford and explained this new problem Whit was instantly hooked. This led him to travel the country visiting researchers at Harvard, MIT, IBM Watson, and the NSA to try to learn as much as he could about cryptography. Eventually, he met Martin Hellman and as they say, the rest is history… Interview with Whitfield Diffie recorded at the 2021 Heidelberg Laureate Forum. Produced by Dr Tom Crawford at the University of Oxford.
