K-Confidentiality for Discrete Event Systems

Abstract

Cybersecurity has become crucial in a world where virtually all activities and processes are networked interconnected. This research addresses the importance of cybersecurity, especially in cyber-physical systems, where the integration of systems across various domains raises concerns about security against cyberattacks. More specifically, one vulnerability of these networks pertains to the information transmitted through there communicantion channels. A malicious intruder can uncover industrial secrets through the transmitted information. Therefore, it is important to ensure the confidentiality of the literature, toK-confidentiality, where confidentiality will be guaranteed only for k observations by the attacker. While this is a limitation of the original definition of confidentiality, with this strategy, it is possible to algotihmaically ensure that the K-confidentiality of the system is assured by creating a cryptographic system, thus avoiding limitations imposed on secret sequences.
