Currently, AES is regarded as the most popular symmetric cryptographic algorithm. It is very significant to develop high performance AES to further broaden its widespread applications. And in this paper, it is mainly about the different optimized designs and implementations of AES algorithm. Firstly, it tests the fast implementation of AES algorithm and the performance has been improved by about 50 times when compared to the standard AES algorithm, Secondly, using the Intel AES-NI extended instruction sets, and the performance has been improved by about 50 times compared with the fast implementation of AES algorithm, Finally, using CUDA and GPU to execute the AES in parallel, and it can improve the performance by about 18 times compared with the fast implementation of AES algorithm.
