Unwinding and the LOCK proof referees study

The LOCK definition of non-interference and the LOCK unwinding theorem provide a method of using a non-interference model in a system with an identified potential for interference. However, the LOCK work is presented in terms specific to the LOCK system. The authors generalize the LOCK definitions and theorems so that they could be used in systems other than LOCK that have specifically identified potentials for interference They state and prove a general winding theorem for this purpose. They also show that the LOCK unwinding theorem follows from their general unwinding theorem
