Notes on Electronic Payment Systems
The ease of purchasing and selling products over the Internet has helped the growth of electronic commerce and electronic payments services are a convenient and efficient way to do financial transactions. Current e-payment technologies depend on using traditional methods that are common to non-electronic systems. Due to the nature of Internet, security and authenticity of payments and participants cannot be guaranteed with technologies that are not specifically designed for electronic commerce. We need an e-payment system that would not only provide secure payments but should also have properties like online customer and merchant authentication, unforgeable proof of transaction authorisation by the customer both to the merchant and the bank, privacy of customer and transaction data. This chapter provides an overview of e-payment architecture and their functionalities, their requirements and verification of payment protocols.
Cryptographic Protocols in Electronic Payment Systems
The focus of this research was to study electronic payment systems and their security mechanism that can be achieved using cryptographic techniques. The primary aim was to analyse security properties and to identify weaknesses present in those systems that have been implemented in a public domain. The research consisted of analysis of prominent credit card payment systems like SET, Verified by Visa, MasterCard SecureCode, electronic cheque systems like FSTC eCheck protocol.
Implementation of Anonymous Auction System
The aim of this research was to implement an anonymous auction system along with an e-cash system. We describe the framework of an anonymous auction system and the softwares that was used to implement such a system.
