Abstract

Message sequence charts (MSC) are widely used in the early design of communication protocols. They allow describing the communication skeleton of a system. We consider a basic verification task for hierarchical MSCs, the matching problem via MSC templates. We characterize the complexity of checking properties which are expressible by and-or templates, resp. by LTL formulas. Both problems are shown to be PSPACE-complete.
