A coordination-based access control model for space-based computing
Stefan Craß, Eva Kühn · 2012
Shared tuple spaces serve as coordination medium for independent processes to exchange data and messages in a flexible way. If communication takes place over the Internet, security becomes an important issue. It must be forbidden that unauthorized processes get access to protected data. In this paper, we present an authorization model for a space-based middleware that uses its own coordination mechanisms for defining fine-grained access control policies. By integrating coordination and security mechanisms into one single concept, the model allows for flexible and secure distributed collaboration.
