Implementation Of MD5 Integrity Checking Mechanism For m-Commerce Transactions
R. Ganesan, M. Gobi, VS Janakiraman · 2008
migrates from e-commerce to m-commerce the issue of maintaining integrity of transactions takes a pivotal role. To implement m-commerce applications, Sun Java Wireless Toolkit is generally adopted. This is a state-of-the-art toolbox for developing wireless applications that are based on J2ME's Connected Limited Device Configuration (CLDC) and Mobile Information Device Profile (MIDP), and designed to run on cell phones, mainstream personal digital assistants, and other small mobile devices. In J2EE environment, the md5 implementation is available to ensure integrity. However, md5 implementation is not available in J2ME environment. With majority of applications moving to m-commerce environment, it becomes pertinent to develop and implement a class in Sun Java Wireless Toolkit that can ensure integrity of transactions. In this paper, we describe message digest class for the same, and present the technical details. This message digest has been implemented and tested on a Sun Java Wireless Toolkit 2.5.1 emulator. Using the Sun Java Wireless Toolkit, it is also possible to generate .jar files which can be uploaded to mobile devices.This implementation, in our view, finds wide applications in all m-commerce transactions where integrity of data is of prime importance.
