Abstract: Non-repudiation is the main problem in the application of electronic commerce. This paper describes the principle of digital signature algorithm based on CA technology, and the certificate authority tree structure to ensure the execution of the digital signature. It also describes how to apply such technology in a typical electronic payment system, and the solutions for these practical problems.
