Abstract

A method for achieving mutual authentication and session key agreement between a first party (12) that has a minimal computational resources and a second party (18) that has substantial resources uses a modular square root operation for certificate authentication and key distribution and an ELGamal, NIST DSS, or other efficient signature operation for obtaining the signature of a message. The second party (18) is connected to a switching system (23) in a central office (22).
