Design and analysis of AES-CM with non-linearity S-box architecture

This paper is concerned with the use of commercial security algorithms like the Advanced Encryption Standard (AES) in Earth observation small satellites. The demand to protect the sensitive and valuable data transmitted from satellites to ground has increased and hence the need to use encryption on board. For that AES, which is a very popular method, it is slowly emerging as the preferred option in the aerospace industry including satellites. This paper first addresses the encryption of satellite imaging data using one of the AES modes-CM with new type of S-box techniques and it will be implemented in Virtex-4.
