A Critical Study: Secure Gateway in Payment System for Electronic Transaction

In this paper the attempt of studying a Secure Gateway in payment system for Electronic transaction is made. The current research and development shows that the electronic payment system for such an electronic transaction is to be secure for participants such as Payment Gateway Server, Bank Servers and Merchant Servers, on Internet. The security architecture of such systems are designed by using various Security Protocols and Techniques, not only to safeguard but eliminate the fraud that occurs in such a transaction with stolen credit card/debit card payment information and customer information. Electronic commerce involves the tremendous exchange of some form o f money for trade of goods and services over the Internet, and it is evident from the studies that the Internet is an insecure and unreliable media in many ways in such a trade. The primary goal of this paper is to review the asymmetric key crypto-system methodology that uses Security Protocol, the Secure Communication Tunnel Techniques that protect conventional transaction data such as account numbers, Card number, amount and other information, and to finally provide secure implementation for such an electronic transaction on the Internet.
