摘要：With the development of the information technology, using Internet to pay for goods and services has become a very popular application. The traditional forms of payment can not be applied to e-commerce environment. Because of the complexity of online transactions related to capital flows and goods flows, the transaction process requires higher security and reliability. One mature approach for ensuring reliability is to use formal methodologies. In this paper, we employ model checking method to verify the security and reliability of the Internet Payment Systems. A PROMELA model for the System is present. As an important part of our modeling methodology, we translate the Internet Payment System into a simpler model that nevertheless preserves all the essential behavior to be verified. We also propose initial results on the actual verification of the Internet Payment System using SPIN. The result of our work is a complete procedure for the modeling and verification of the Internet Payment System.
