The techniques modern used to encrypt text data play an important role in preventing unauthorized access. The AES algorithm is widely used in various cryptographic applications, but coz the algorithm has been subjected to several successive attacks, the need is necessary to improve the algorithm and make it more powerful the algorithm.In dis search will be inserted plaintext 1024 will be divided into four blocks each Block consists of 256 bits and each Block will pass the four stages represent(substitution,shift,Mix column and round key).A new step will be added to the four stages of permutation. Where chaos theory is adopted …
