Abstract

1

Accessing information over the Internet has become an essential requirement in modern economy, and unknown parties can come together on the Net and interact for the purpose of acquiring or offering services. The open and dynamic nature of such scenario requires the development of new ways of enforcing access control. A promising direction is re- presented by the use of digital certificates, or credentials. To this purpose, new credential- based access control languages, models, and mechanisms need to be investigated.
