An Innovative Approach to Enhance the Security of Data Encryption Scheme

In this paper, we proposed a new scheme to enhance the security of data Encryption scheme. With cascading of data encryption standard in three times, we become able to counter the famous meet in middle attack in double and triple data encryption standard. We show how the random key stream can be used to create lifetime supply of keys for one time pads. Here we provided the practical approach that we can use to set up our own one-time pad encryption. For simplicity lets study how randomized key can be achieved. Random key generation can simply be obtained via use of permutation. Permutation technique can be used in conjunction with other technique includes substitution, encryption function etc. for effective performance. The goal of this article to show how the one-time pad encryption technique can be achieved by the suitable combination of these techniques.

An Authenticated Two-Tier Security on Transmission of Medical Image using Codebase Cryptosystem over Teeming Channel

In this paper, we present an efficient and authentic transmission scheme without digital signature on an algebraic coding theory based public key cryptosystem of medical information like Image, Audio, Video etc. via the combination of stegnographic and cryptographic approach. Stegnographic approach facilitates data hiding, McEliece public-key cryptosystem to encrypts the data,.lossless compression provides us integrity and Fuzzy error correction provides error less message over noisy channel.

An Approach to Secure Data with Authentication & Integrity using EHDES over Noisy Channel

Today’s era of communication is too much important. An effective communication requires major factors like: Authentication, Confidentiality, Integrity, etc. In this current paper, we introduce a complete security that provides by the combination of stegnographic approach and cryptographic schemeEHDES (Enhanced Data Encryption Standard). Stagnographic approach facilitates data hiding and EHDES encrypts the data to be transmitted. A lossless compression provides us integrity. Fuzzy error correction provides error less message over noisy channel.
