Nidhi Garg, Neeta Wadhwa . Design of New Hash Algorithm with Integration of Key based on the Review of Standard Hash Algorithms. International Journal of Computer Applications. 100, 8 ( August 2014), 11-18. DOI=10.5120/17544-8128
Cryptographic Hash Functions are main building block of message integrity. These functions have many information security applications such as Digital Signatures, Message Authentication, Data Integrity and Key derivation. This paper presents comparative study of standard hash algorithms (MD5, SHA-1 and SHA-2), their security aspects and recent attacks. In this paper, a new hash algorithm with integration of key is proposed. This key is a shared secret key 'KEY' of 192-bit. The proposed algorithm produces a hash code of 192 bits from an arbitrary length input and serves the requirement of both the message integrity as well as source authentication. This algorithm consists of very simple steps, therefore would have lesser overhead and complexity as compared to the standard hash algorithms.
