An Introduction of Advanced Encryption Algorithm: A Preview

In a recent era, Network security is playing the important role in communication system. Almost all organization either private or government can transfer the data over internet. So the security of electronic data is very important issue. Cryptography is technique to secure the data by using Encryption and Decryption Process. Cryptography is science of secret information it is the art of hiding the information by Encryption and Decryption. Encryption is the process to convert the Plaintext into unreadable format known ciphertext. and Decryption is the process to convert cipher text into plaintext. Numbers of algorithm used for encryption and Decryption like DES, 2DES, 3DES, RSA, RC2, RC4, RSA, IDEA, Blowfish, AES but AES algorithm is more efficient and Effective AES algorithm is 128 bit block oriented symmetric key encryption algorithm. In this paper I describe the brief introduction of AES algorithm. My paper is divide into following Section. In I Section I Present the brief introduction of AES (Advance Encryption Standard) Algorithm, In II Section I Present the different Cryptography algorithm, In III Section I Present comparison of AES algorithm with different cryptography algorithm, In IV Section I Present the Modified AES algorithm and Text and Image Encryption by using AES algorithm, In V Section I Present Future Enhancement of AES algorithm and Conclusion.
