Formation and sending of rekeying messages (305, 415, 515, and 605) in an encrypted communication system with over-the-channel rekeying of communication units is performed by a KMC, key management controller (101). The KMC (101) forms messages to provide new keys (1541), zeroization information (1549), and key indexing information (1543) to communication units (107), and to provide keyloader upload data (1563). Acknowledgments and rekey requests are also handled between the KMC (101) and communication units (107).
