| Abstract: | The reconfiguration of the key expansion and MixColumn blocks is analyzed, a reconfigurable architecture based on key expansion and MixColumn blocks is proposed, and the high-speed implementation of the AES algorithms which support three keys length of 128 bit,192 bit and 256 bit on the reconfiguration architecture is given. The simulation results show that the area of AES circuit is finely optimized. |
