Context-based security (and safety) meta-policies for pervasive computing environments: the case of smart momes
نویسندگان
چکیده
Context-based security is an approach for modeling adaptive security solutions based on the situation of use of the system. Security policies in this approach are not static as it used to be in traditional systems. The security actions to be taken are based on the knowledge of the combination of various factors such as the location of the user, the surroundings, time, temperature etc making the security policies more adaptive. The aim of this paper is to present security meta-policies based on an existing approach known as Contextual Graphs and the multilevel access model, which we presented in our previous paper. These meta-policies determine within what contexts actions in other policies should be taken – it is in this sense that we have the notion of other policies “embedded” within the meta-policy. Our approach can be easily used in various smart environments, even for context-aware safety meta-policies. The paper presents their use in a smart home scenario.

A semantic-aware role-based access control model for pervasive computing environments
Access control in open and dynamic Pervasive Computing Environments (PCEs) is a very complex mechanism and encompasses various new requirements. In fact, in such environments, context information should be used in access control decision process; however, it is not applicable to gather all context information completely and accurately all the time. Thus, a suitable access control model for PCEs...
متن کاملA context-sensitive dynamic role-based access control model for pervasive computing environments
Resources and services are accessible in pervasive computing environments from anywhere and at any time. Also, due to ever-changing nature of such environments, the identity of users is unknown. However, users must be able to access the required resources based on their contexts. These and other similar complexities necessitate dynamic and context-aware access control models for such environmen...

Mandatory access control models have traditionally been employed as a robust security mechanism in multilevel security environments such as military domains. In traditional mandatory models, the security classes associated with entities are context-insensitive. However, context-sensitivity of security classes and flexibility of access control mechanisms may be required especially in pervasive c...

The vision of Pervasive Computing is that every device we communicate today has become a part of everyday objects, augmented with information services. Though there are a number of frameworks is been developed for security of smart systems, there is still space for research in the field of security of these systems. User privacy and Trust needs more concentration in a pervasive environment. Con...
