Enhanced Secure Algorithm for Message Communication

Abstract

This paper puts forward a safe mechanism of data transmission to t ackle the security problem of information which is transmitted in Internet.The encryption standards such as DES (DataEncryption Standard), AES (Advanced EncryptionStandard) and EES (Escrowed Encryption Standard)are widely used to solve the problem of communication over an insecure channel. Withadvanced technologies in computer hardware andsoftware, these standards seem not to be as secureand fast as one wouldlike. In this paper we propose a encryption technique which provides security to both the me ssage and the secret key achieving confidentiality and authentication . The Symmetric algorithm usedhas two advantages over traditional schemes. First, the encryption and decryption procedures are much simpler, and consequently, much faster. Second, the security level is higher due to the inherent poly-alphabetic nature of the substitution mapping method used here, together withthe translation and transposition operations performed in the algorithm.Asymmetric algorithm RSA is worldwide known for its highsecurity. In this paper a detailed report of the process is presented and analysis is done comparing our proposed technique with familiar techniques
