  • Error recovery of encrypted data frames in multi-node systems
    Patent number: 10719411
    Abstract: A method of performing error recovery of encrypted data frames is disclosed. A data packet is received, and a decryption operation is performed on the data packet. The data packet is compared with one or more data packets stored in a recovery buffer to identify a duplicate of the data packet when the decryption operation fails. One or more bits affected by one or more bit errors are identified based on a comparison between the data packet and the duplicate of the data packet. Different combinations of bit values for the one or more bits are determined. The decryption operation is performed on the data packet with the different combinations to identify a correct combination of bit values for the one or more bits. The data packet is recovered (e.g., corrected so that it can be decrypted and consumed) based on the correct combination of bit values.
