  • Abstract
    In this paper, we propose an efficient encryption scheme by introducing randomness into the Lempel-Ziv-Welch (LZW) algorithm. This scheme utilizes random dictionary insertion and permutation, and incorporates with a bit-wise XOR module. Security analysis results show that the proposed scheme provides high level of security without any coding efficiency loss, compared with a standard LZW algorithm.
