A team of cryptography experts is confident they have the answer as to how the NSA and other intelligence agencies break individual encrypted connections. The great mystery since the NSA and other ...

Tens of thousands of HTTPS-protected websites, mail servers, and other widely used Internet services are vulnerable to a new attack that lets eavesdroppers read and modify data passing through ...

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 ...

Quantum Q-Day threatens encryption; organizations must prepare now.

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 ...

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 ...
