Patent ID: 7681036

Claim:
A multi-channel radio operating with multiple security levels, comprising: more than one input, each input corresponding to a security level; a first set of more than one processors, each of the processors in the first set of more than one processors is coupled to one of the inputs, each of the processors in the first set of more than one processors corresponding to the security level of the respective input; and a second set of more than one processors coupled to the first set of more than one processors via a first common bus; wherein a first processor in the first set encodes and encapsulates data, a data source, and a destination address to generate an encrypted outbound packet, the first processor being configured to append a channel identifier onto the encrypted outbound packet to generate a channel encrypted outbound packet, the first processor being configured to append the data source and the destination address onto the channel encrypted outbound packet and re-encapsulate the channel encrypted outbound packet; wherein a re-encapsulated channel encrypted outbound packet is configured to be able to be decoded by at least one processor assigned to the first security level in the second set, the re-encapsulated channel encrypted outbound packet being further configured to not be able to be decoded by at least one processor assigned to a second security level in the second set; wherein the first common bus is configured to direct the re-encapsulated encrypted outbound packets to the at least one processor of the second set.
