Abstract-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 let's 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.
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 scheme-EHDES (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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
