The optimization of AES algorithm
The AES has been used a lot in the world, because of its high security and low computation complexity.In order to further optimize the AES, firstly, this paper will introduce the principle and the process of AES algorithm.Then, it will optimize the round transformation process which is the most timeconsuming in AES.We will improve the round transformation by using displace function and changing the four steps of round transformation into inquiry of the look-up table and XOR operation.This will allow a multi-step operation for each round into one step.Finally, the test proves that the optimized AES is significantly improved than the previous AES.
