Abstract

Advanced Encryption Standard (AES), also known as Rijndael, is an encryption standard used for securing information. AES was published by NIST (National Institute of Standards and Technology). AES is a block cipher algorithm that has been analyzed extensively and is now used widely. AES is a symmetric block cipher that is intended to replace DES as the approved standard for a wide range of applications. The block cipher Rijnddael was designed by Dr. Joan Daemen and Dr. Vincent Rijmen and the name of the algorithm is a combination of the names of its two creators. Rijndael is very secure and has no known weakness. Rijndael is conventional (symmetric key) system and is relatively simple cipher in many respects. It takes an input block of a certain size, usually 128, and produces a corresponding output block of the same size. The transformation requires a second input, which is the secret key. It is important to know that the secret key
