Encryption and Decryption Images Using AES Algorithm

In today's world, data security is a major issue to be addressed.To secure, store and transmit data during communication use Advanced Encryption Standards (AES).AES is a symmetric block cipher that aims to replace DES for commercial applications.It uses a block size of 128 bits and a key size of 128, 192 or 256 bits.AES algorithm is used to secure data from unauthorized users.AES algorithm is available for text data as well as image data.In this paper, an image is given as input to AES encryption algorithm which gives encrypted output.This encrypted output is given as input to AES decryption algorithm and the original image is restored as output .
