A secure and efficient software protection model for electronic commerce

摘要

Today software piracy is a major concern to electronic commerce since a digitized product such as software is vulnerable to redistribution and unauthorized use. This pa- per presents an enhanced electronic software distribution and software protection model. Authentication scheme of the pro- posed model is based on zero-knowledge(ZK)proof which re- quires limited computation. The proposed model considers post installation security using authentication agent. It prevents soft- ware piracy and illegal copy. It also provides secure and efficient software life-update mechanism based on traitor tracing scheme.
