Extension of battery lifetime has always been a major issue for mobile computing. While more and more data are involved in mobile computing, energy consumption caused by I/O opera...
- Recently, pervasive and ubiquitous computing evolved tremendously and has become an integral part of many fields. This is widely attributed to their efficiency in integrating wit...
For an efficient role based access control using attribute certificate in highly distributed computing environments, we use a technique of structuring role specification certificat...
Developments in ubiquitous and pervasive computing herald a future in which computation is embedded into our daily lives. Such a vision raises important questions about how people...
Role-based access control (RBAC) has attracted considerable research interest. However, the computational issues of RBAC models are yet to be thoroughly studied. In this paper, we...
