- Abstract
- This paper presents a compact 8-bit AES hardware architecture suitable for low-area and lowpower applications such as wireless network devices. Unlike the conventional 32-bit architecture which uses 8 S-boxes to implement the SubBytes transformation and the InvSubBytes transformation, the 8-bit architecture presented in this paper requires only 2 Sboxes. In addition, the number of XOR gates used by the MixColumns & InvMicColumns transformation module in the proposed 8-bit architecture can be reduced to less than half of those used in the 32-bit architecture.
