Over the last decade, opacity of discrete event systems (DES) has become a very fertile field
of research. Driven by safety and privacy concerns in network communications and online …

This paper presents historical remarks on key projects and papers that led to the
development of a theory of event diagnosis for discrete event systems modeled by finite …

Correct-by-construction synthesis is a cornerstone of the confluence of formal methods and
control theory towards designing safety-critical systems. Instead of following the time-tested …

Opacity is a confidentiality property that captures whether an intruder can infer a “secret” of a
system based on its observation of the system behavior and its knowledge of the system's …

In this paper, we formulate and analyze methodologies for verifying the notion of initial-state
opacity in discrete event systems that are modeled as non-deterministic finite automata with …

In the context of security analysis for information flow properties, where a potentially
malicious observer (intruder) tracks the observed behavior of a given system, infinite-step …

Abstract System resilience captures the ability of the system to withstand a major disruption
within acceptable performance degradation and to recover within an acceptable time frame …

We describe and analyze the complexity of verifying the notion of infinite-step opacity in
systems that are modeled as non-deterministic finite automata with partial observation on …

In this paper, we study the verification and enforcement problems of strong infinite-step
opacity and k-step opacity for partially observed discrete-event systems modeled by finite …

State-based notions of opacity, such as initial-state opacity and infinite-step opacity, emerge
as key properties in numerous security applications of discrete event systems. We consider …
