摘要:

授权决策是访问控制理论研究中的关键问题之一。为了有效提高基于信任的访问控制中授权的安全性,依据最小风险贝叶斯决策理论,将访问控制中客体对主体的授权视为最优决策的发现问题,提出基于风险最小化授权映射方法,实现访问控制中准确的授权操作。通过算例分析和仿真实验表明,该方法能够在降低风险的情况下比较准确地给出交互的最终授权。

Abstract:

Authorization decision was one of the key issues in the control access.In order to effectively enhance the security of authorization in trust based access control authorization,according to minimization risk Bayes decision theory,authorization was the object to the subject in access control as found that the problem of optimal decision.A method that minimizates risk based authorization mapping to realize correct authorization operation in the access control was proposed.Example analysis and simulation experiment show that the method is able to reduce risk accurately to interaction final authorization.

Key words: access control, Bayes decision theory, trust, risk, authorization mapping
