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 ...

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 ...

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 ...

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 ...

Martin Hellman achieved legendary status as co-inventor of the Diffie-Hellman public key exchange algorithm, a breakthrough in software and computer cryptography. That invention and his ongoing work ...
