ABSTRACT:
A method of message authentication in an encrypted communication system with over-the-channel rekeying features the ability of a communication unit (107) to authenticate (1709) a rekeying message (701) from a key management controller (101) using a message number (1517A) comparison, thereby preventing outside interference from unauthorized rekeying message transmissions.
