Abstract
A method for storing and managing rekeying information for a secure communication system, as well as for carrying out a rekeying operation. Encryption key variables stored in memory (301) are represented by mnemonics (303) as part of an editable data base (302) that is arranged in the same order as communication unit key storage locations. Each communication unit (305) within the system is assigned to a specific group (304), while each group (304) is assigned to a particular editable data base (302).
