摘要
The multi-agent negotiation test-bed proposed by Collins was modified. It utilizes publish/subscribe system, time-release cryptography and anonymous communication. The proposed protocol reduces DOS attack and avoids replay data attack by providing ticket token and deal sequence number to the supplier. And it is proved that generating random number to the supplier by market is better than the supplier doing it by him in guaranteeing anonymity. Market publishes an interpolating polynomial for sharing the determination process data. It avoids collusion between a customer and a certain supplier. According to the comparison and analysis with other protocols, the proposed protocol shows good security and better efficiency.
