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 ...

In the realm of secure communications, data exchange and secret key agreement algorithms are pivotal for establishing confidentiality and ensuring the integrity of information transmitted over ...

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 ...

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 ...

It’s actually possible for entities with vast computing resources – such as the NSA and major national governments – to compromise commonly used Diffie-Hellman key exchange groups, so it’s time for ...

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 ...

To protect users from cryptographic attacks that can compromise secure web connections, the popular Firefox browser will block access to HTTPS servers that use weak Diffie-Hellman keys. Diffie-Hellman ...
