Ad hoc grid security infrastructure

This paper describes an ad hoc grid security infrastructure developed as a part of the Java CoG Kit project. It supports several requirements specific to the sporadic nature of ad hoc grids. It focuses on identity management, identity verification, and authorization control in spontaneous grid collaborations without pre-established policies or environments. It adopts established community standards, with modifications where needed. This paper also discusses the integration of the ad hoc grid security infrastructure in an ad hoc grid implementation. The implementation supports secure collaboration in ad hoc grids using commodity technologies such as the Java CoG Kit, JXTA, GSI, and XACML.
