More Information
Summary:In one example herein, apparatus and methods enable continuously combining the contents of each transmitted message and subsequent retransmitted message even when a unique nonce is used for each encrypted message. The received data stream is decrypted and re-encrypted on the fly to meet all the requirements of real-time soft combining of the decrypted payload and the validation of the encrypted CRC. In another example, the currently received message payload is decrypted on the fly so that it can be soft-combined in real time with previously decrypted messages. The corrected message payload is re-encrypted on the fly so that the CRC verification can be performed on combined encrypted data.
