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 ...

Quantum Key Distribution (QKD) represents a paradigm shift in secure communications by using the fundamentally unpredictable behaviour of quantum systems to exchange cryptographic keys 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 ...

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 ...

The Kerberos authentication protocol is the default authentication protocol of Windows Server 2003. This section examines how the protocol works by breaking down the complexity of the protocol into ...
