A Type Inference Algorithm for Secure Ambients

Barbanera, F., Dezani, M., Salvo, I. and Sassone, V. (2001) A Type Inference Algorithm for Secure Ambients At Theory of Concurrency, Higher Order and Types, TOSCA Workshop 2001.. , 19 pp.

Record type: Conference or Workshop Item (Paper)


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.
