Abstract

Fuzzy logic was introduced as a mathematical treatment for vague information, being very important in cryptography mostly because its appliance in authentication process. We propose an identity authentication and a key agreement protocol based on fuzzy logic which is recommended for group communication. The users authenticate themselves to a server, and not to each other. The common key is generated using biometric data. The protocol has low complexity due to the fact that the authentication and the key agreement are done simultaneously.
