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 an important information-flow property that arises in security and privacy analysis
of cyber–physical systems. Among many different notions of opacity, K-step opacity requires …

This paper investigates the enforcement of opacity by insertion functions subject to multiple
quantitative constraints capturing resource or energy limitations. There is a malicious …

Opacity is an important information-flow security property in the analysis of cyber-physical
systems. It captures the plausible deniability of the system's secret behavior in the presence …

Opacity, as an important property in information-flow security, characterizes the ability of a
system to keep some secret information from an intruder. In discrete-event systems, based …

We investigate the problem of synthesizing dynamic masks that preserve the infinite-step
opacity in the context of discrete-event systems. Dynamic mask is an information acquisition …

Security of distributed control systems is affected by the presence of information leaks, which
permit to external intruders to infer the state of the system itself. Noninterference deals with …

Opacity is an important information-flow property concerning the security and privacy of
cyber–physical systems. We investigate the synthesis problem of infinite-step opacity and K …

This article develops a novel compositional and abstraction-based approach to synthesize
edit functions for opacity enforcement in modular discrete event systems. Edit functions alter …

In this article, we investigate the enforcement of opacity via supervisory control in the context
of discrete-event systems. A system is said to be opaque if the intruder, which is modeled as …
