Security of multimedia data is an imperative issue because of fast evolution of digital data exchanges over unsecured network. Multimedia data security is achieved by methods of cryptography, which deals with encryption of data. Most of the application uses Advanced Encryption Standard (AES) and modify it, to reduce the calculation of algorithm and for improving the encryption performance. In modified AES algorithm used 1-Dimensionla S-box instead of 2-Dimensional S-box. This paper presents verilog Implementation of Modified Advanced Encryption Standard Algorithm using Xilinx Software. MAES is a lightweight version of AES which meets the demand. A new one-dimensional substitution Box (S-box) is proposed instead of conventional 2-D S-box and previous 1-D S-box.
