This paper presents a new AES S-Box hardware design based on the optimization of linear mappings by combining multiplicative and exponential offsets. In general, the performance of efficient AES S-Box hardware with composite field representations depends largely on the construction of linear mappings (i.e., transformation matrices) between AES polynomial field and the composite field before and after S-Box. Multiplicative and exponential offset techniques have been reported previously for obtaining the optimal transformation matrix, but the optimization combined with both techniques has been applied only to S-Box of Boyar-Peralta type variants. In this paper, we propose an application of multiplicative and exponential offsets to AES S-Box hardware based on redundant Galois field arithmetic. In particular, we design two types of the S-Box hardware: one for only encryption (ENC) and another for both encryption and decryption (ENC/DEC), and evaluate their performances by logic synthesis using Nangate 45nm Open Cell Library. From the evaluation applied area optimization constraints results, we show that the proposed S-Box hardware for ENC and ENC/DEC improves by 23.2% and 20.1% in the area delay product, respectively, compared with the conventional S-Box hardware based on redundant Galois field arithmetic. Moreover, we show that the proposed S-Box hardware for ENC and ENC/DEC is up to 8.7% and 28.8% better in area delay product, respectively, even compared with the most efficient ones. In the evaluation with frequency optimization constraints, we also show that proposed S-Box hardware for ENC and ENC/DEC achieve higher performance in comparison with the conventional ones. |
