Implementation aspects of Advanced Encryption Standard (AES) Contest finalist algorithms (MARS, RC6, RIJNDAEL, SERPENT and TWOFISH) are studied on TMS320C54X processor. The C codes written by Brian Gladman in 1999 are adapted to TMS320C54X and the speed and memory usage values are compared with the adaptation of Karol Gorski and Michal Skalski&rsquo / s implementation in 1999. The effects of implementation environment are investigated by comparing the two implementations. The sensitivities of the finalist algorithms to plaintext, key and key length variations together with the possible reasons are studied and scrutinized. Three of the algorithms, MARS, RC6 and RIJNDAEL, are implemented on the same platform by using the assembler language. The results show that assembler implementations are improved with respect to C implementations 13% for MARS, 16-20% for RIJNDAEL and 21-28% for RC6.
