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 ...

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 ...

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 ...

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 ...

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 ...

Dozens of adoring, young Chinese university students (and not-so-young infosec professionals) surround Martin Hellman, posing for selfies that are surely destined for WeChat. The cryptographer and ...

A researcher challenges a conclusion in a recent academic paper on weak Diffie-Hellman implementations that claims 66 percent of IPsec VPN connections are at risk. A challenge has been made against ...

The concept of cryptography touches our lives many times per day, and that’s probably a conservative estimate. We have a pretty good idea of how it works, having dealt with public-key cryptography for ...
