tor/decryptor core implementation of Advanced Encryption Stan- dard (AES-Rijndael) cryptosystem. The suggested architecture is capable of handling all possible combinations of standard bit lengths (128,192,256) of data and key. The fully rolled inner- pipelined architecture ensures lesser hardware complexity. The architecture does reutilize precomputed blocks, in the sense that the same hardware is shared during encryption and decryption as much as possible. The design has been implemented on Xilinx XCVe1000-8bg560 device. The performance of the architecture has been compared with existing results in the literature and has been found to be the most efficient (throughput/area) implemen- tation of the AES algorithm. Index Terms--Reconfigurable Architecture, AES, Rijndael, S- box, Composite fields.
