Abstract-- The Grid offers significant opportunities for
performing wide area distributed computing, allowing multiple

diminish the level of collaboration that is possible, and current
Grid middleware often assumes that there are no restrictions on
the type of communication that is allowed. Accordingly, a
number of collaborations have failed because the member sites
have different and conflicting security policies.
In this paper we present an architecture that facilitates inter-
organization communication using existing Grid middleware,
without compromising the security policies in place at each of the
