Abstract: According to the security problems in network commerce, a trusted center architecture based on intrusion tolerance and its algorithm of hybrid encryption are designed with identity-based cryptography. A scheme of identity-based security collaborative commerce platform is proposed based on that. The scheme has better performance compared with the traditional ones based on certificate. Analysis indicates that the scheme is secure, efficient and suitable for networked manufacturing.

Key words: identity-based cryptography, networked manufacturing, collaborative commerce platform, intrusion tolerance

摘要： 针对网络商务的安全问题，利用基于身份的密码体制，设计一个基于容忍入侵的可信中心安全架构及其加密算法，以此为核心提出一个基于身份的协同商务平台安全方案。与基于证书的方案相比，该方案无须维护庞大的证书库、系统开销小、可信中心安全性高。性能分析表明，该方案是安全高效的，适用于网络化协同商务平台。
