Abstract

The principal goal of designing any encryption algorithm is to hide the original message and send the non-readable text message to the receiver so that secret message communication can take place over the web. The strength of an encryption algorithm depends on the difficulty of cracking the original message. A number of symmetric and asymmetric key encryption algorithms like DES, TRIPLE DES, AES, BLOWFISH, RSA has been developed to provide greater security affects one over the other. I have described a  protocol in this paper, which fits  the  technique  to realistic  communication  environments,  and  extend  the  security  and  the  range  of applications of the  technique. The basic motive behind the new approach is not to use a ‘key’. Encryption is done by the use of the logic operations amongst the bits of the code word. This can be said as "security through obscurity" where the shared secret is not an encryption key, but the encryption algorithm itself. This algorithm can prove to be an efficient method of encryption and can reduce the complexity of a system that encrypts or decrypts a message. Analysis has been done which shows the advantages and the limitations of this algorithm. With this new approach we are implementing a technique to enhance the security level and to further reduce the time for encryption and decryption.
