Analysis of the Effective Advanced Encryption Standard Algorithm

Abstract: Now aday�s civilization is hugely dependent upon electronic and communication system. In this electronic world, increasing need of data protection in computer networks is necessaryfor the development of several cryptographic algorithms and tosend data securely over a transmission link from one person to another person.AES is one of the better algorithms for secured transmission than the traditionalalgorithm. In this AES algorithm, various steps are required toencrypt and decrypt. The AES algorithm uses cryptographic keys of 128, 192, and 256 bits to encrypt and decrypt data on block size of 128 bits. The algorithm is synthesized and simulated using Xilinx ISE and Model Simsoftware and results are comparedwith previous work.AES algorithm is implemented on hardware as well as software which provide higher security.
