STRENGTHENING AND ACCELERATING AES BASED ALGORITHM

Secure communication has been longstanding concern of mankind, starting by the Code of Caesar and until today algorithms with symmetric, asymmetric encryption and hash functions to ensure data integrity. We have built an MDS matrix (maximal separable distance) that will be added during the AES algorithm encryption and decryption process. We have modified the AES algorithm to boost its security, which in fact has increased the number of calculations within the algorithm rounds. That the greater numbers of calculations have no impact on coding or decoding delay at the end we propose the parallel version of this algorithm.
