摘要: 提出一种面向信任的角色委托授权模型(Trust-RBDM)。在基于角色的访问控制模型的基础上引入信任基,并在用户和信任基之间建立映射关系,依靠可信链的传递实现委托授权,有效解决了传统委托授权模型委托操作分散和安全性差的问题。将该模型应用于基于HOOPS的3D协同设计中,实验结果表明,该模型能够增强分布式协同设计环境中委托授权的灵活性和安全性。

Abstract: A new Trust-oriented RBDM (Trust-RBDM) is constructed. Trust base is introduced on the base of RBAC model while the relationship mapping is established between the users and the trust bases. The delegation is realized by trust chain, so it can resolve the traditional RBDM’s decentralized operation and inferior security effectively. This model is applied to 3D cooperative design based on HOOPS and experimental results indicats that the model can enhance the delegation’s flexibility and security.

Key words: access control, delegation, trust base
