Access Control for Documents in Ad-hoc Networks

In this paper we consider requirements and implementation issues of an access control system in open, ad hoc networks. Ad hoc networks differ from fixed, wired networks in several important aspects, one of them being that access to the Internet is not always available. This significantly influences access control systems, since online access to various access control servers is not always possible. In this paper we specify security requirements and constraints in such environments and outline some potential solutions for adaptation of access control systems to these environments.
