A Type Inference Algorithm for Secure Ambients.
In, Theory of Concurrency, Higher Order and Types, TOSCA Workshop 2001.
We consider a type discipline for the Ambient Calculus that associates ambients with security levels and constrains them to be traversed by or opened in ambients of higher security clearance only. We present a bottom-up algorithm that, given an untyped process $P$, computes a minimal set of constraints on security levels such that all actions during runs of $P$ are performed without violating the security level priorities. Such an algorithm appears to be a prerequisite to use type systems to ensure security properties in the web scenario.
