Trust management system has been a promising approach to solve the access control problems in open multi-domain environments. However, the calculation of trust and the delivery of the trust are not addressed effectively in the existing trust management systems. To address the problems, this paper proposes a scheme of trust calculation and delivery control.(More)
To address the distributed certificates searching problem in trust management, the member set and privilege set are defined, the forward, backward and bidirectional distributed certificates searching algorithms based on the definitions are brought forward, the complexity of the algorithms and also the comparison of the algorithms and existing algorithms are(More)
In this paper, a new authorization delegation model is proposed, which is based on weighted directed graph to present the trust relationship between the entities and the existing issues, such as the evaluation of the trust and the presentation of the trust among the entities are addressed in simple and visual way. The model and the corresponding algorithm(More)
