云制造系统用户认证和服务间协同高效可信安全技术

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.
