The selective application of technological and related procedural safeguards is an important responsibility of every organization in providing adequate security to its electronic data systems. Now as the world is moving towards high speed of communication (larger data rate), more secure and fast algorithms are required to keep the information secret. In the present work, a new model is proposed and implemented, which is very similar to the conventional AES. The fundamental difference in the AES and proposed model is in block size which has been increased from 128 bits in conventional AES to 200 bits in proposed algorithm. The proposed algorithm is giving very good randomness and hence enhances the security in comparison to conventional AES.
