The system is conventional or trunked Over-The- Air-Rekeying (OTAR). A Key Management Control- ler (KMC) is used to send encryption keys to radios. Radios have a Key Encryption Key (KEK) in com- mon with the KMC. This allows the KMC to send traffic encryption keys (TEKs), over-the-air, encrypted with the KEK, to the radio. TEKs are used for voice traffic in the system.
