摘要
为了提高AES算法在硬件平台上的实现性能,通过对AES算法S盒构造原理进行分析,构造了一个新S盒。与AES算法的S盒相比,新S盒在硬件实现时将使用更少的硬件资源并具有更快的运行速度,因而更适合在低档硬件上实现。同时,分析并证明了新S盒不会影响修改后的AES算法的强度。
To promote the performance of AES in hardware, a new S box for AES was constructed thorough analyzing the structure of AES S box. Compared to the AES S box, the most important feature of new S box is that it can implement with a small amount of gates and get faster processing, so it is more applicable in resource constrained device. Meanwhile, the characteristics of the S box and the safety of the modified AES were analyzed, which proves the safety to AES with new S box.
