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 کاملPolicy Enforcement System for Inter-Organizational Data Sharing
Sharing data among organizations plays an important role in security and data mining. In this paper, the authors describe a Data Sharing Miner and Analyzer (DASMA) system that simulates data sharing among N organizations. Each organization has its own enforced policy. The N organizations share their data based on trusted third party. The system collects the released data from each organization,...
متن کاملDC Proposal: Knowledge Based Access Control Policy Specification and Enforcement
The explosion of digital content and the heterogeneity of enterprise content sources have resulted in a pressing need for advanced tools and technologies, to support enterprise content search and analysis. Semantic technology and linked data may be the long term solution to this growing problem. Our research explores the application of access control to a knowledge discovery platform. In order ...
متن کاملThe Policy Machine: A novel architecture and framework for access control policy specification and enforcement
The ability to control access to sensitive data in accordance with policy is perhaps the most fundamental security requirement. Despite over four decades of security research, the limited ability for existing access control mechanisms to generically enforce policy persists. While researchers, practitioners and policy makers have specified a large variety of access control policies to address re...
متن کاملCRePE: Context-Related Policy Enforcement for Android
Most of the research work for enforcing security policies on smartphones considered coarse-grained policies, e.g. either to allow an application to run or not. In this paper we present CRePE, the first system that is able to enforce fine-grained policies, e.g. that vary while an application is running, that also depend on the context of the smartphone. A context can be defined by the status of ...
