摘要： 隐私保护是多域间资源共享、协同合作的关键性安全问题。在分析现有访问控制模型隐私泄漏问题的基础上，提出了一种支持隐私保护的角色访问控制模型。该模型以基于身份的密码体制为基础，避免了传统角色访问控制模型的诸多弊端，实现了多域环境下的隐私保护，并利用随机预言模型对该模型的安全性进行了详细的分析和证明。分析表明该模型满足INI}CCA2语义安全。通过实验仿真表明该模型具有较好的实用性。

Abstract: Privacy preservation is a vital problem to share resource and collaboration among multi-domains. We analyzed the privacy leakage problems of current access control models, and then proposed a rolcbased access control model supporting privacy preservation. The model is based on identify-based encryption,avoiding a number of drawbacks in traditional role-based access model and making privacy preservation among multi-domains come true. Finally, we analyzed and certificated the security of the model in details by random oracle, and the model meets the IND-CCA2 mantic security. According to the simulation, the method is a practical model.
Key words: Access control, Privacy protection, Identify-based encryption, Police expression, Random oracle
