Existing mandatory access control systems for operating systems are difficult to use. We identify several principles for designing usable access control systems and introduce the...
Reputation and Trust-based Monitoring Systems (RTMSs) have provided a ubiquitous framework for secure Wireless Sensor Network (WSN) computing. Employing sensors for neighborhood m...
Access to distributed databases containing tuples collected about mobile physical objects requires information about the objects’ trajectories. Existing access control models ca...
