In this paper, the structure and design various AES algorithms have been analyzed, remarking its main advantages and limitations, as well as its similarities and dissimilarities with each other. Thus, the fact that the new cipher and its inverse use different components, which practically eliminates the possibility for weak and semi-weak keys, is one of the principal advantages of these algorithms. Also, the nonlinearity of the key expansion, which practically eliminates the possibility of equivalent keys, is another big advantage. The importance of the Advanced Encryption Standard and the high security of the various algorithms have been examined. Finally, the authors' experimental results show that superior performance can be achieved compared with other software implementations.
