A Modified approach for implementation of an efficient padding scheme in a digital signature system

摘要

In order to provide secure transaction of documents over an insecure channel, Digital Signature Systems are made use of and Hash function is an eternal component of it. The requirement of devising an improved approach to reduce the impact of attacks in Cryptanalysis formed a driving force behind the emergence of changes in padding and parsing schemes used from time to time. However, it has been found that these schemes have not proved to be completely as efficient as this critical application demands. Therefore, there is always a scope for their improvement. The paper is organized into parts; in the first ones we give an overview of hash functions and a brief presentation of its use in Digital Signature. However the rest of parts are consecrated for our proposed improvement for padding structure and comparative results drawn from correlation coefficients obtained, finishing the paper by a conclusion and future extension of this work.
