Access Control for Security and Privacy in Ubiquitous Computing Environments
Ubiquitous computing (ubicomp) demands new security and privacy enhancing technologies for the new information and communication environments where a huge number of computers interact with each other in a distributed and ad hoc manner to access various resources and services. This paper surveys emerging security and privacy enhancing technologies, focusing on access control in ubiquitous comput...
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...
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 کاملMultilevel Access Control for Ubiquitous Environments
This paper presents a domain-based approach to access control in distributed environments with mobile objects and nodes. We utilize a slightly different notion of an object’s ’view’, by linking its context to the state information available to it for access control purposes. In this work, we tackle the problem of hiding sensitive information in insecure environments by providing objects in the ...
متن کاملDynamic Access Control for Ubiquitous Environments
Current ubiquitous computing environments provide many kinds of information. This information may be accessed by different users under varying conditions depending on various contexts (e.g. location). These ubiquitous computing environments also impose new requirements on security. The ability for users to access their information in a secure and transparent manner, while adapting to changing c...
