In the 1970s, Whitfield Diffie co-wrote the recipe for one of today’s most widely used security algorithms in a paper called “New Directions in Cryptography.” The paper was a blueprint of what came to ...

In my previous article/video how does encryption work? I wrote about the principles of encryption starting with the Caesar cipher and following the development of cryptography through to the modern ...

Communicating "in the clear", Alice and Bob select two numbers, q and n. Alice then selects the secret number xa. Bob selects the secret number xb. From the two public numbers, q and n, and her secret ...

In discussing the Visual Studio Code Name "Orcas" January 2007 CTP I mentioned its managed classes for Elliptic Curve Diffie-Hellman and Elliptic Curve Digital Signature Algorithm cryptographic ...

Modern digital security relies heavily on encryption algorithms grounded in difficult math problems, which is the backbone of what’s known as public-key infrastructure (PKI). From securing websites to ...

A formula used to turn ordinary data, or "plaintext," into a secret coded message known as "ciphertext." The ciphertext can reside in storage or travel over unsecure networks without its contents ...

Crypto pioneer Diffie on the developments in encryption and the relevance of PKI. (Part of the What Happens Next security predictions series.) In the 1970s, Whitfield Diffie co-wrote the recipe for ...
