A Novel and Fast Encryption System Based on Improved Josephus Scrambling and Chaotic Mapping

A Novel and Fast Encryption System Based on Improved Josephus Scrambling and Chaotic Mapping

To address the shortcomings of weak confusion and high time complexity of the existing permutation algorithms, including the traditional Josephus ring permutation (TJRP), an improved Josephus ring-based permutation (IJRBP) algorithm is developed. The proposed IJRBP replaces the remove operation used...
