ACM Transactions on Information and System Security, 2005 Securing access to data in location-based services and mobile applications requires the definition of spatially aware access-control systems. Even if some approaches have already been proposed either in the context of geographic database systems or context-aware applications, a comprehensive framework, general and flexible enough to deal with spatial ...

Cryptographically Enforced RBAC [PDF]
2013 IEEE 26th Computer Security Foundations Symposium, 2013 Cryptographic access control promises to offer easily distributed trust and broader applicability, while reducing reliance on low-level online monitors. Traditional implementations of cryptographic access control rely on simple cryptographic primitives whereas recent endeavors employ primitives with richer functionality and security guarantees ...

How to Securely Break into RBAC: The BTG-RBAC Model [PDF]
2009 Annual Computer Security Applications Conference, 2009 Access control models describe frameworks that dictate how subjects (e.g. users) access resources. In the Role-Based Access Control (RBAC) model access to resources is based on the role the user holds within the organization. Although flexible and easier to manage within large-scale authorization frameworks, RBAC is usually a static model where access ...
