Bounds on the number of markings consistent with label observations in petri nets
(2009)In this paper, we consider state estimation in discrete-event systems (DESs) modeled by labeled Petri nets and present upper bounds on the number of system states (or markings) that are consistent with an observed sequence ...

Verification of initial-state opacity in security applications of DES
(2008)Motivated by security applications where the initial state of a system needs to be kept secret (opaque) to outside observers (intruders), we formulate, analyze and verify the notion of initial-state opacity in discrete ...
