Executive Summary

The protection of information authentication is based on cryptographically secure hash function. A function that compresses an arbitrarily large message into a fixed small size message digest' is known as a hash function. The most currently used hash functions are based on block ciphers and the dedicated hash functions e.g. MD5, SHA-0 and SHA-1 etc. A hash function is said to be broken if an attacker is able to show that the design of the hash function violates at least one of its claimed security property. In present paper, the authors are planning to design and develop an efficient and effective hashing scheme for information authentication. They will try to design a hashing method which has certain features like speed and more security.
