摘要： 在分析现有合同网模型的基础上，针对合同网协商过程中的安全问题，利用Bit承诺协议和RSA算法，给出一个具有安全性的合同网协商模型，保证Agent之间信息的安全传输，防止协作Agent反悔、拒绝履行承诺。该协商模型满足不可否认性和强可验证性，投标价格保密安全，技术简单，通信量小。

Abstract: Based on the analysis of the current contract net model, this paper proposes an architecture for multi Agents. To ensure security, it gives a secure contract net model using a Bit commitment protocol and RSA algorithm, which implements both encryption and digital signature. It has high quality of security and can satisfy all the secure requirements of bid unforgeability, result verifiability, bid secrecy.

Key words: contract net, Bit commitment, Agent security, RSA algorithm
