Abstract
A radio frequency communication system subscriber (110) has a unique identification code, public key and private key, and stores the identification code and public key for other system subscribers in its memory (115). When transmitting, the subscriber includes its identification code in a transmitted message (160) and encodes the transmitted message with its private key. When receiving, the subscriber authenticates a received message (170) by accessing the sending subscriber (120)'s identification code from the message, retrieving the sending subscriber's public key from memory and decoding the message with the retrieved key.
