Abstract
Cryptographic hash function assumes a fundamental job in numerous pieces of cryptographic algorithm and conventions, particularly in authentication, non-repudiation and information trustworthiness administrations. A cryptographic hash work takes a commitment of optional tremendous size message and conveys a fixed little size hash code as a yield. In the proposed work SSLHA-160 (a strong and secure lightweight cryptographic hash algorithm), each 512-digit square of a message is first diminished to 256-bit. A cryptographic hash work takes a contribution of discretionary enormous size message and delivers a fixed little size hash code as a yield. In the proposed work SSLHA-160 (A strong and secure lightweight cryptographic hash algorithm), each 512- digit square of a message is first diminished to 256-bit and afterward partitioned into eight equivalent block of 32 pieces each and each 32-cycle block is additionally separated into two sub-block of 16-piece each. These two sub-blocks go about as two purposes of an elliptic curve, which are utilized for computing another point which is of 16 pieces. The new point esteems are thusly handled to produce message digest. SSLHA-160 is easy to develop, simple to actualize and displays solid torrential slide impact (avalanche), when contrasted with SHA1, RIPEMD160 and MD5.
Highlights
Authentication is a significant idea in information security, and one method of accomplishing this by utilizing hash function
RIPEMD is a gathering of hash work which is created by Hans Dobbertin, Antoon Bosselaers and Bart Preneel in 1992
When the given message is slightly changed, this results in huge alteration in the yield due to the avalanche effect, which is a property of Hash function
Summary
Authentication is a significant idea in information security, and one method of accomplishing this by utilizing hash function. A Hash function is a mathematical function that maps a message of variable size into a small-length esteem called message digest. One direction hash function is a variation of the message authentication code. A single direction hash function, otherwise called a message digest, is a numerical function that takes a variable-length input string and converts it into a small-length arrangement that is computationally hard to alter—that is, going in back direction is impossible create the information from the hash. Message confirmation and gadget verification can be accomplished through this hash code or message digest. In Area 3, proposes a strong and secure lightweight cryptographic hash algorithm SSLHA160, planned dependent on elliptic curve ideas.
