Security has become an increasingly important feature with the growth of electronic communication. The symmetric in which the same key value is used in both the encryption and decryption calculations are becoming more popular. AES is a symmetric encryption algorithm processing data in block of 128 bits. Under the influence of a key, a 128-bit block is encrypted by transforming it in a unique way into a new block of the same size. In this paper, the authors main concern are study AES algorithm and implement all modules of AES algorithm on FPGA.
