Real-world problems are often formulated as diverse properties of different types of
dynamical systems. Hence property verification and synthesis (ie, enforcement) have been …

In this paper, we revisit the verification of strong K-step opacity (K-SSO) for partially-
observed discrete-event systems modeled as nondeterministic finite-state automata. As a …

To ensure opacity, it is optimal to retain as many as possible occurring event sequences.
Contrary to this problem, the other optimal goal is to preserve the minimal occurring event …

In this paper, we investigate the verification and enforcement of strong state-based opacity
(SBO) in discrete-event systems modeled as partially-observed (nondeterministic) finite …

The opacity-enforcement problem in discrete-event systems is one of ensuring that an
adversarial observer cannot determine a given system's secret. Although the problem has …

Recently, topics of security have been explored in the field of discrete-event systems (DES).
By modelling these systems with DES, the evolution of the processes can be captured …
