  • Maintaining synchronization of encryption process across devices by sending frame numbers
    Patent number: 10110945
    Abstract: Maintaining synchronization of encryption processes at devices during transmission of encrypted data over a communication link is provided. Cipher link maintenance characters are sent from a source device to a sink device. A local cipher link maintenance character generated at the sink device for decrypting the encrypted data can be adjusted according to the cipher link maintenance character. After authentication, cipher link maintenance characters corresponding to units (e.g., frames) of the encrypted data are sent along with the units of the encrypted data. When a transmission error occurs during transmission of the encrypted data, cipher link maintenance characters can be used to correct the error in a local cipher link maintenance character generated at the sink device. Hence, even if the transmission error occurs in the communication link, the sink device can resolve the transmission error and maintain the synchronization of encryption processes at the source and sink devices.
