Implementation of cryptography technique using AES algorithm

Abstract

All of the cryptographic algorithms we have looked at so far have some problem. The earlier ciphers can be broken with ease on modern computation systems. As a result of technology scaling and higher integration densities there may be variations in parameters and noise levels which will lead to larger error rates at various levels of the computations. As far as memory applications are concerned the soft errors and single event upsets are always a matter of problem. As a result of technology scaling and higher integration densities there may be variations in parameters and noise levels which will lead to larger error rates at various levels of the computations. As far as memory applications are concerned the soft errors and single event upsets are always a matter of problem. In this project we add the key and shuffle the data it is very hard for the unknown person to find out the original data. Since for each key there will be a change in the cipher text and so the person has to know the key in order to find out the original data.
