Executive Summary

In this paper, the authors proposed a new scheme to enhance the security of data encryption scheme. With cascading of data encryption standard in three times, they become able to counter the famous meet in middle attack in double and triple data encryption standard. They show how the random key stream can be used to create lifetime supply of keys for one time pads. Here they provided the practical approach that they can use to set up the 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.
