An Innovative Approach to Enhance the Security of Data Encryption Scheme

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.
