Security is playing a very important and crucial role in the field of network communication system and Internet. Data Encryption Standard (DES) is a private key cryptography system that provides the security in communication system but now-a-days the advancement in the computational power the DES seems to be weak against the brute force attacks. To improve the security of DES algorithm the transposition technique is added before the DES algorithm to perform its process. By using an Enhanced DES algorithm the security has been improved which is very crucial in the communication and field of Internet.
