  The new <A HREF="http://simon.cs.cornell.edu/Info/Projects/HORUS/"> Horus</A> security architecture will permit arbitrary trust relationships among the processes within a group. This is accomplished by using a key management scheme which does not allow one process in a group to impersonate another group member. Using this scheme, a process group may trivially achieve the semantics provided by the original security architecture (however with a slightly higher overhead). However, unlike the original security architecture, the new architecture enables the implementation of groups (such as client/server groups) which many have more complicated trust relationships among group members.  <HR>  <H3>
