ABSTRACT:
This method of key distribution locates (401,501) an individual communication unit (107) within an encrypted communication system with over-the-channel rekeying and then rekeys (415, 515) the unit. The method uses a key management controller (101) to manage and distribute keys (1541) and handle acknowledgments that are either immediate or delayed from receipt of the rekeying message.
