云制造系统用户认证和服务间协同高效可信安全技术

针对云制造系统不同安全域之间信任关系孤立导致的用户跨域访问重复进行身份认证和云服务跨域协同被拒绝的问题, 设计了一种面向云制造系统的域间互信过程模型, 提出了基于域间互信的用户认证和服务跨域协同高效可信安全优化技术, 实现了用户可信身份跨域传递和云制造服务跨域协同, 并在企业进行了应用验证, 给出了所提方法与传统方式的对比分析。分析结果表明, 提出的高效可信安全技术能够在提升云制造系统认证和服务跨域协同效率的同时不降低现有安全机制的防护强度。

Efficient trusted security technology of user authentication and service collaboration in cloud manufacturing system

Aiming at the problem that the isolation of trust relationship between different security domains of cloud manufacturing system leads to the repeated identity authentication of users' cross domain access and the rejection of cloud service cross domain collaboration, an inter domain mutual trust process model for cloud manufacturing system is designed. An efficient trusted security optimization technology of user authentication and service cross domain collaboration based on inter domain mutual trust is proposed, which realizes the cross domain transmission of users'trusted identity and cloud manufacturing service cross domain collaboration. The application is verified in some enterprises, and a comparative analysis with the traditional method is given. The analysis results show that the efficient and trusted security technology proposed can improve the efficiency of cloud manufacturing system authentication and service cross domain collaboration without reducing the protection intensity of the existing security mechanism.
