SET for E-Commerce Transactions
The Secure Electronic Transaction (SET) is a protocol designed for protecting credit card transactions over the Internet. It is an industry-backed standard that was formed by MasterCard and Visa (acting as the governing body) in February 1996. To promote the SET standard throughout the payments community, advice and assistance for its development have been provided by IBM, GTE, Microsoft, Netscape, RSA, SAIC, Terisa, and Verisign.
SET relies on cryptography and X.509 v3 digital certificates to ensure message confidentiality and security. SET is the only Internet transaction protocol to provide security through authentication. It combats the risk of transaction information being altered in transit by keeping information securely encrypted at all times and by using digital certificates to verify the identity of those accessing payment details. The specifications of and ways to facilitate secure payment card transactions on the Internet are fully explored in this chapter.
