A transmitting device generates a header, at least one data block, a first message authentication code (MAC), and an authentication indicator to create a trunking control message. The trunking control message is transmitted to a receiving device, such that, upon receipt of the trunking control message by the receiving device, the receiving device can generate a second MAC. Once the second MAC is generated, the receiving device compares the second MAC to the first MAC. The at least one data block is determined to be authentic if the second MAC matches the first MAC. If the at least one data block is authentic, the receiving device processes the at least one data block; otherwise, the receiving device discards the trunking control message.
