Secure Wireless Payment Protocol

Abstract

With the convergence of wireless data communication and the Internet, more and more Internet services are now being used in the wireless area. Mobile payment protocols are necessary for online transactions. A good payment protocol should balance the requirements of security and convenience. WAP (Wireless Application Protocol) is one of the prevalent wireless technologies being embraced by the banking sector. Compared with WLAN (Wireless Local Area Network), WAP can satisfy the strong security requirement of banking services. WPP (Wireless Payment Protocol) is a convenient lightweight protocol that supports both credit card and debit card transactions in wireless environment. The shortcoming of WPP is that it does not actually address security. In this paper, we propose a new wireless payment protocol, SWPP (Secure Wireless Payment Protocol), to address security and convenience based on WAP for WTLS (Wireless Transport Layer Security), WIM (Wireless Identity Module) and WMLScrypt, WPKI technology.
