Use of Digital Signature to Enhance Data Security

Abstract

The security of information in any organization was primary concern since the advent of paperwork. Thousands of years ago the sensitive information and documents were preserved in cabins and lockers. With the invention of computer and as the world progressed issue of information security also became a serious concern. In digital signature security of messages is assured so that the information can be transferred from one end to another without any threat to integrity of a message and documents. In digital signature scheme the sender first signs a documents which send to receiver either directly or by a trusted third party. The recipient on receiving the messages validates the signature through an algorithm that is known as DSA or Digital Signature Algorithm. This scheme of digital signatures ensures that the information received is secured verified Integrated and authenticated. This makes the digitally signed document secure from forgery and any other foreign attacks that may prove to be a threat to security of data and information. This paper describes the devious factors of digital signature which helps in the working of electronic signature and also through various ways and procedures it involve the signing of the data which we use in digital signature.
