Abstract

Radio frequency based telecommunication systems often require both subscriber units (100) and communications units (130) of a fixed network communication system to maintain secret data which may be used to verify authenticity as well as provide encrypting variables for message encryption processes. An efficient real-time authentication method and apparatus are provided which use a single message (210) to provide authentication and communication link setup information. Further, an authentication method and apparatus are provided which uses instant-specific information such as a time of day, radio frequency carrier frequency, a time slot number, a radio port number, access manager identifier, a radio port control unit identifier, or a base site controller identifier to enhance the reliability of the authentication process. Furthermore, a method and apparatus are provided for maintaining secure packet data communications through an encryption process by utilizing a packetized message encryption key (502) and a unique packet number (504) as encryption variables.
