Proposal of a New Block Cipher reasonably Non-Vulnerable against Cryptanalytic Attacks

Abstract

This paper proposes a new block cipher termed as “Modular Arithmetic based Block Cipher with Varying Key-Spaces (MABCVK)” that uses private key-spaces of varying lengths to encrypt data files. There is a simple but intelligent use of theory of modular arithmetic in the scheme of the cipher. Based on observed implementation of the proposed cipher on a set of… (More)
