In this paper, the authors include implementation of Advanced Encryption Standard technique (AES) means to encryption and decryption of data is 128-bit using the AES and its modified high security and reliability. The process of encryption consists of the combination of various classical techniques known as rearrangement, substitution and transformation encoding techniques. The encrypting and decrypting modules include the expansion of key which generates Key for all iterations. Cryptography importance are applied to security in electronic data transactions has acquired an essential relevance during the last few years.
