Implementation of Digital Signature in Authentication for E-Trading System

Abstract

Applications of digital signature technology are on the rise because of legal and technological developments, along with the strong market demand for secured transactions on the Internet. The internet based on the network are become essential tools in today. Also based on the network, communications for the business or trading become wide information society. So, information security is needed to cover the most of threads over the network. Information security means not only for storing and communication data in secrete but also for ensuring that the source of message is valid and the message has not been altered. Digital signatures are used to detect unauthorized modifications to data and to authenticate the identity of the signatory. The proposed system is intended to implement the Digital signature in Authentication for E-trading System by using DSA algorithm. This system also covers for confidentiality by applying RC5 algorithm. This system provides not only for security infrastructure for online e-trading system but also for digital signature products and online security, it is important to understand the application development trends in digital signature technology.
