Improvement of Channel Decoding Using Block Cypher
This paper introduces two methods for the improvement of performance of channel coding using cryptography, based on concatenation of codes. Cryptography as an outer code is combined with channel coding as an inner code. The first method improves decoding of cryptographic functions. The second one uses the first method for improvement of information decoding using a block cipher Advanced Encryption Standard. Computer simulation results are included. This paper researches the interoperability between channel coding and cryptography in order to reduce BER of the channel decoding.
