Internet Key Exchange (IKE) is a standard protocol used to set up a secure and authenticated communication channel between two parties via a virtual private network (VPN). The protocol ensures ...

Encrypted key exchange is a protocol, or set of rules, that allows two parties sharing a common password to communicate over an insecure network without exposing that password. The protocol was ...

Key exchange with unilateral authentication (short: unilateral key exchange) is an important primitive in practical security protocols; a prime example is the widely deployed TLS protocol, which is ...

A team of five researchers from two Chinese universities and the Chinese Academy of Sciences has published a geometric attack that breaks two post-quantum authenticated key exchange protocols that had ...

A series of exploits have been found in the wild targeting Windows Internet Key Exchange (IKE) Protocol Extensions. According to a new advisory recently shared by security company Cyfirma with ...

Establishing secure channels is one of the most important areas of cryptographic research. Secure channels provide secrecy and authenticity for both communication parties. When parties can share ...

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 ...
