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 ...

Adjust the colors to reduce glare and give your eyes a break. Use one of the services below to sign in to PBS: You've just tried to add this video to My List. But first, we need you to sign in to PBS ...

Usually, when you hear about broken cryptography, it’s because of some sort of nonmathematical workaround to compromise supposedly encrypted traffic—like intercepting traffic during brief periods when ...

Organizations that move sensitive data over HTTPS, SSH, or VPNs can prepare for post-quantum by using encryption in transit ...

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 ...

A cryptographic key exchange method developed by Whitfield Diffie and Martin Hellman in 1976. Also known as the "Diffie-Hellman-Merkle" method and "exponential key agreement." Diffie-Hellman enables ...

On Tuesday, a team of computer scientists released a report (.PDF) documenting cryptographic problems with the Diffie-Hellman key exchange, a popular algorithm used by Internet protocols to agree on a ...

The Firefox browser will now deny TLS connections to servers using weak Diffie-Hellman keys. Logjam was one of several downgrade attacks discovered in the last 18 months that could theoretically allow ...

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 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 ...
