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 paper presents an enhanced electronic software distribution and software protection model. Authentication scheme of the proposed model is based on zero-knowledge (ZK) proof which requires limited computation. The proposed model considers post installation security using authentication agent. It prevents software piracy and illegal copy. It also provides secure and efficient software live-update mechanism based on traitor tracing scheme. Even if software or personal key is copied illegally, a merchant can trace back to its original owner from the electronic license and personal key. The proposed model provides security and reasonable performance and safety.
