New Approach for Serpent Block Cipher Algorithm Based on Multi Techniques

Abstract

complexity and easy to used are two important properties in the block cipher .The size of the block cipher controls these two aspects .data security means data protecting and information systems from unauthorized: enter to center data, used this data, disclosure, disruption, modify, perusal, inspection, recording or destruction. Information security is a set combining organizational security and IT security. In this paper proposal new approach for serpent algorithm by depend on modify in process and round because the tradition the operation in original serpent structure has more time and sample of complexity this algorithm used to encryption wave media ,in this paper has new structure has many of technique as (Mix Column,S-Box,IP,IP-1) to increase more complexity.
