DESIGN AND IMPLEMENTATION OF GEOMETRIC BASED CRYPTOGRAPHIC HASH ALGORITHM: ASH-256
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 7
Abstract
Online communication takes a major part in our daily life. Since sending or receiving information over internet is inevitable, usage of hash function is essential to check whether the information is correct or not especially for sensitive or confidential information. In this paper a new cryptographic hash function, Algorithm for Secure Hashing (ASH-256) has been proposed which is based on geometric concepts. In ASH-256, each 64-bit block of a given 512-bit block is increased to 96-bits by using Expansion table (E-Table) of DES(Data Encryption Standard) algorithm and divided into two equal sub-blocks. Each sub-block is used to generate three points of a triangle, which are involved in area calculation. The calculated area values are in turn processed to generate message digest. ASH- 256 is more secure and exhibits strong avalanche effect and also simple construction and easy to implemention, when compared to standard hash function SHA2(256).
