This paper presents an architectural model for contextual-based delegation access control for pervasive computing, particularly access control mechanisms for ad hoc coalition scen...
Object-oriented databases are a recent and important development and many studies of them have been performed. These consider aspects such as data modeling, query languages, perfo...
We build concurrently executable blind signatures schemes in the common reference string model, based on general complexity assumptions, and with optimal round complexity. Namely, ...
Utility computing is a service provisioning model which will provide adaptive, flexible and simple access to computing resources, enabling a pay-per-use model for computing simila...
In this paper we propose an access control model for use by a trusted middleware infrastructure, which is part of an architecture that supports the operation of Location Based Serv...
