Abstract: Advanced Encryption Standard (AES) is the current standard for secret key encryption. AES was created by two Belgian cryptographers, Vincent Rijmen and Joan Daemen, to overcome the disadvantages of Data Encryption Standard (DES). The Federal Information Processing Standard 197 used a standardized version of the algorithm called Rijndael for the Advanced Encryption Standard. The algorithm uses a combination of Exclusive-OR operations (XOR), substitution with an S-box transformation, row and column rotations, and a MixColumns. All the transformations of encryption are simulated using an iterative design approach in order to minimize the hardware consumption.To reduce manual operations a verilog code is developed ,synthesis and simulations of code is done by using Xilinx and Modelsim.It was successful because it was easy to implement and could run in a reasonable amount of time on a regular computer.
