Abstract:
1. A method for encryption and decryption synchronization for a communications channel comprising: encrypting a communications channel using a data encryption device, the communications channel comprising a data stream having unique information native to the data stream; transmitting the encrypted data stream using a transmitter without applying an additional framing structure or a multiplexing signaling message before or after the data stream is encrypted such that the encrypted data stream does not require additional bandwidth to support cryptographic synchronization; receiving by a receiver comprising a decryption device, the transmitted encrypted data stream; and identifying the unique information within the transmitted data stream by iteratively decrypting the encrypted data stream using a processor until a cryptographic parameter is found that results in cryptographic synchronization between the encryption and decryption devices based on a priori knowledge of the unique information within the transmitted data stream.
