Abstract
The present disclosure relates to a system and method of encrypting and decrypting Optical Transport Network (OTN) payload content. A transmitter of the system includes a series of ordered encryption keys and a counter for generating an initialization vector to be combined with one of the encryption keys for encrypting the OTN payload content. A receiver of the system includes a series of ordered decryption keys and a counter for generating an initialization vector to be combined with one of the decryption keys for decrypting the encrypted OTN payload content. The system synchronizes switching, at the transmitter and the receiver, the encryption and decryption keys to the next keys in each series. The system also synchronizes the counters for generating the same initialization vector at the transmitter and the receiver.
