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 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 ...

For the third time in less than a year, security researchers have found a method to attack encrypted Web communications, a direct result of weaknesses that were mandated two decades ago by the U.S.
