Dynamic access control method of pervasive computing

Abstract

The present invention discloses an access control method for common computing environment. The method realizes dynamic access control by combining a hierarchy credit mode with a role-based access control mode. The hierarchy credit mode is a structure with two hierarchies, wherein the bottom credit value determines the role assignment; the upper credit value determines the role activation and the permitted activation. The upper credit value is related to applied context, different upper credit values correspond to different activated roles and permission, thus the obtained service is different. The method is mainly applied in solving the problem of authorization in common computing environment as well as in realizing access control to the applied resources in other dynamic environments.

Description

Technical field [0001] The invention relates to a dynamic access control method, which is mainly used to solve the authorization problem in the pervasive computing environment. Background technique [0002] Ubiquitous computing is the fusion of information space and physical space. In this fusion space, people can obtain digital services transparently anytime and anywhere. But this ubiquitous and mobile environment brings new security concerns. Due to the unpredictability of the subjects that cooperate with each other, traditional access control technologies for static networks or closed systems cannot be used in pervasive computing environments. [0003] One of the main features of ubiquitous computing is the rich interactive interface between users and resources, which can use a variety of multimedia input and output methods to participate in the operation, management and maintenance of smart spaces. Due to the nature of the way users interact, it is unlikely that a smar...

Problems solved by technology

It solves the problem that traditional access control cannot handle distributed authorization, but this capability-style system cannot really solve the distributed authorization feature, it does not solve why trust

Now some researchers have made some useful explorations on access control in ubiquitous computing and related fields, but they have not considered how to control access to unfamiliar subjects, have not considered the characteristics of information space and physical space, and the existence of an authorization process too complicated
