In this paper, we address several design issues related to querying encrypted data in relational databases. Based on our experiments, we propose new and efficient techniques to reduce the cost of cryptog

To address these issues, we propose a form of access control model that is based upon the key notion of an event. The access control model

For critical applications, a formal model for spatio-temporal-based access control is needed that increases the security of the application and ensur

TUCON extends traditional and temporal access control models with times-based usage control by defining the maximum times that a privilege can be exercised.

As a result, most auditing methods, though rigorously studied, can never be implemented in practice for protecting largescale real-world database systems. To shift this paradigm, we propose a new inference control architecture that will entrust inference con
