The Diffie-Hellman algorithm was a stunning breakthrough in cryptography that showed cryptographic keys could be securely exchanged in plain sight. Here’s how it works. Whitfield Diffie and Martin ...

Programmers Whitfield Diffie and Martin E. Hellman, who developed the first form of cryptography for the internet era, have been awarded this year’s Turing Award. Named after famed British ...

Twenty years before the Internet would create a need for it, a public-key cryptographic standard was discovered and patented by Whitfield Diffie, along with another student and a professor at Stanford ...

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 ...
