Abstract — Internet became a part of human life and these days online communication gained more popularity than traditional communication. Eventually paper based documents are replaced by electronic documents. Digital Signature is a security mechanism used to check the authenticity and integrity of an electronic document. It is also used to achieve non-repudiation service, which provides proof for sent or received messages. In this paper we propose a new digital signature scheme using a novel message digest algorithm, ‘Algorithm for Secure Hashing-160 (ASH-160)’. This proposed scheme has been implemented in java and the results are analyzed and compared with RSA digital signature scheme using SHA1 and RIPEMD160. The analysis of experimental results reveals an increase in security strength and slight improvement in the efficiency of RSA with ASH160 than the compared schemes.
