Embodiment 1

[0050] The specific implementation method of the present invention is illustrated below by a specific example in an intelligent classroom, see figure 1 . There is an air conditioner and a printer in the smart classroom Classroom, and a temperature detector is used to monitor temperature changes and a camera is used to monitor the entry and exit of the smart classroom. The access control requirements are as follows: when the teacher is in the smart classroom and the temperature of the smart classroom is suitable, the teacher is authorized to use the printer to a higher degree. When the temperature in the smart classroom drops and the temperature in the smart classroom is higher, reduce the security protection strength of the printer. When the user leaves the smart classroom, the temperature of the smart classroom is high, and when the temperature continues to rise, he is authorized to use the printer to a very low degree.

[0051] In order to achieve the above access control ...

Embodiment 2

[0096] It is the same as under the intelligent classroom environment of embodiment 1. There is an air conditioner and a printer in the smart classroom Classroom, and a temperature detector is used to monitor temperature changes and a camera is used to monitor the entry and exit of the smart classroom. On the basis of the access control requirements of Embodiment 1, the following two access control requirements are added: when the temperature in the smart classroom drops, and when there are users in the smart classroom, reduce the security protection strength of the printer. When the temperature in the smart classroom rises, when there are users in the smart classroom, the security protection strength of the printer is increased.

[0097] 1. Establish a set of active fuzzy rules for access control

[0098] Based on the above access control requirements and expert experience, the security administrator establishes the following two active fuzzy rules for access control on the b...

Abstract

The invention discloses an initiative access control method based on an initiative fuzzy rule, comprising: building an initiative fuzzy rule set of access control, monitoring the fuzzy event of an access control atom, building the composite fuzzy event of access control, triggering the initiative fuzzy rule of access control, researching the fuzzy predicate of access control, determining the interval value degree of membership of the fuzzy predicate of access control, activating the initiative fuzzy rule of access control, calculating an access control reasoning result, and performing the fuzzy motion step of access control. The invention provides the initiative fuzzy rule which can effectively describe an initiative self-adaption access control strategy triggered on the basis of fuzzy events in the ubiquitous computing environment, eliminates a semantics gap between a delegated strategy and an access control strategy as well as practical security requirements, and solves access control limitation and inadaptability of the traditional access control theory and technology when ubiquitous computing environment is processed.

Description

technical field [0001] The invention belongs to the technical field of security of computing systems, and in particular relates to an active access control method based on active fuzzy rules for pervasive computing environments. Background technique [0002] Access control grants the subject the authority to access the object based on the pre-defined authorization policy, and effectively controls the process of subject's use of the authority according to the pre-defined access control policy, so as to realize the authorized access of system resources and prevent unauthorized information leakage. It is one of the core technologies to ensure the security of computing systems. [0003] Ubiquitous computing is a new computing model proposed by Mark Weiser in 1991. It has been recognized by domestic and foreign academic and industrial circles as the mainstream model of future computing. Ubiquitous computing highly integrates the real world (physical space) and computing world (v...
