Opacity Of Discrete Event Systems: Analysis And Control, Majed Mohamed Ben Kalefa
Wayne State University Dissertations
The exchange of sensitive information in many systems over a network can be manipulated
by unauthorized access. Opacity is a property to investigate security and
privacy problems in such systems. Opacity characterizes whether a secret information
of a system can be inferred by an unauthorized user. One approach to verify security
and privacy properties using opacity problem is to model the system that may leak confidential
information as a discrete event system. The problem that has not investigated
intensively is the enforcement of opacity properties by supervisory control. In other
words, constructing a minimally restrictive supervisor to limit the system's …
