Cryptography, being one of the techniques that is handed out for securing a network. It is utilized by implementing many different algorithms. DES (Data Encryption Standard) is one of the most popular algorithms. But a network implementing DES can be attacked. Hence Triple DES and AES (Advanced Encryption Standard) were formulated to overcome some of the shortcomings of DES. Even then loop holes were found in Triple DES too. In order to plug these loop holes, the new approach Triple DES in a secured way by injecting message digest to it. This paper uses the conventional EDE (Encryption Decryption Encryption) technique as used in triple DES. With the help of two keys transmission, network itself processes with three keys each of 56 bits in length internally and also describes the effectiveness of new approach.
