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 ...

On Tuesday, the Association for Computing Machinery, the nation’s leading organization for computer science, awarded its annual top prize of $1 million to two men whose name will forever be ...

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 ...

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 ...

Researchers have devised a way to place undetectable backdoors in the cryptographic keys that protect websites, virtual private networks, and Internet servers. The feat allows hackers to passively ...

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 ...

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 ...
