Alternating-time Temporal Logic and jMocha Sebastian Wandelt Alternating-time Temporal Logic (ATL) is an extension of the Computation Tree Logic (CTL). jMocha is an interactive verification environment for the modular verification of heterogeneos systems. This project tries to apply the logic ATL and its extension ATEL to so-called mix networks. For doing so, a model checking algorithm for ATEL is presented. Furthermore, a specification of a general mix network is given and some simple properties are checked. Finally the applicability of jMocha will be discussed and some alternatives will be raised.
