摘要: 访问控制是普适计算安全的一项关键技术。然而, 由于普适计算的分布式、模糊和动态特征, 传统的访问控制理论和方法不完全适合普适计算环境下的安全需求。提出普适计算环境下基于区间值模糊集合理论的访问控制新图式, 来有效刻画普适计算环境下访问控制的模糊性和不确定性, 建立模糊受控系统安全新概念, 对模糊受控系统的安全特性进行分析, 为普适计算建立模糊访问控制的理论和方法基础。应用实例分析表明, 提出的面向普适计算的模糊访问控制是有效的。

Abstract: Access control is a key technique for the security of pervasive computing. However, due to the distributed, fuzzy and dynamic characteristics of pervasive computing, traditional access control theories and methods are not always suitable to security requirements for pervasive computing. Based on the interval-valued fuzzy set and fuzzy inference, this paper proposes a novel fuzzy access control paradigm to effectively describe the fuzziness and uncertainty of access control in the environment of pervasive computing, presents the new concepts of the security of fuzzy controlled system, and analyzes the security property of fuzzy controlled system so that the new theory and method of fuzzy access control are created for pervasive computing. The application instance shows that the pro-posed fuzzy access control for pervasive computing is effective.

Key words: pervasive computing, access control, fuzzy uncertainty, interval-valued fuzzy set, fuzzy authorization inference
