Claim 19:
20. A method for secure communication in a wireless cooperative broadcast network comprising:
forming a wireless cooperative broadcast network, wherein the wireless cooperative broadcast network includes a plurality of devices, each device having one or more processors, non-transitory memory and a plurality of instructions executable by one of the one or more processors;
encrypting/decrypting, by one of the one or more processors, a datagram using an inner layer encryption/decryption protocol and a distinct inner layer cryptographic key forming an encrypted/decrypted datagram, and thereafter broadcasting the datagram encrypted/decrypted using the distinct inner layer cryptographic key by/to at least one device within a first group of devices; and
encrypting/decrypting, by one of the one or more processors, the datagram encrypted/decrypted using the distinct inner layer cryptographic key using a distinct outer layer cryptographic key forming an outer layer encrypted/decrypted datagram and thereafter broadcasting the outer layer encrypted/decrypted datagram encrypted/decrypted using the distinct outer layer cryptographic key by/to at least one device of a second group of devices, wherein each device of the first group is a subset of the second group of devices.
