Context-aware Dynamic Access Control for Pervasive Applications∗
نویسندگان
چکیده
As computing technology becomes more pervasive and mobile services are deployed, applications will need flexible access control mechanisms. Unlike traditional approaches for access control, access decisions for these applications will depend on the combination of the required credentials of users and the context and state of the system. In this paper, we extend the role-based access control model to provide dynamic context-aware access control for pervasive applications. The operation of the presented model is illus-

A 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...
متن کاملA 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 کاملCAMAC: a context-aware mandatory access control model
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...

OF THE THESIS Dynamic Context Aware Access Control for Grid Applications by Guangsen Zhang Thesis Director: Professor Manish Parashar While the primary objective of Grid Computing is to facilitate the sharing of resource and service spanning across largely distributed and heterogeneous system, the success deployment of Grid infrastructure will make lots of applications possible. The application...
متن کاملA Dynamic Mandatory Access Control Model
Mandatory access control has traditionally been employed as a robust security mechanism in critical environments like military ones. As computing technology becomes more pervasive and mobile services are deployed, applications will need flexible access control mechanisms. Aggregating mandatory models with context-awareness would provide us with essential means to define dynamic policies needed ...
