A Systematic Way to Provide Security for Digital Signature Using Elliptic Curve Cryptography

E-Commerce [1] is an integral part of our lives now. It has boomed in popularity for both retailers and consumers and this trend is not going to stop anytime soon. The cost-benefits for businesses in overhead and the convenience for shoppers are strong motivators to continue the growth of e-commerce. While there are many benefits of e-Commerce, it is important to remember that there are definitive security challenges that businesses face in e-commerce. But, these are probably not enough to deter merchants (and customers) from engaging in online transactions; still they need to be paid careful attention in order to minimize the risk. Furthermore, E-Commerce is not only limited to a fixed computer it has become wire-free. In this paper the problem undertaken is" Security of Digital Signature in E-Commerce using Elliptic-Curve Cryptography". E-Commerce security strategies deal with two issues: Protecting the integrity of the Business network and its internal systems and with accomplishing transaction security between the customer and the business. We use the concept of RSA (by Rivest, Shamir and Adleman.) and Elliptic Curve Algorithms to implement Digital Signature.
