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 ...

Asymmetric cryptography or public-key cryptography is cryptography in which a pair of keys is used to encrypt and decrypt a message so that it arrives securely. Initially, a network user receives a ...

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 ...

Author Nick Sullivan worked for six years at Apple on many of its most important cryptography efforts before recently joining CloudFlare, where he is a systems engineer. He has a degree in mathematics ...

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 ...

Martin Hellman achieved legendary status as co-inventor of the Diffie-Hellman public key exchange algorithm, a breakthrough in software and computer cryptography. That invention and his ongoing work ...

Researchers have uncovered a flaw in the way that some servers handle the Diffie-Hellman key exchange, a bug that’s somewhat similar to the FREAK attack and threatens the security of many Web and mail ...
