Currentstate opacity formulations in probabilistic finite automata
(2014)A system is said to be currentstate opaque if the entrance of the system state to a set of secret states remains opaque (uncertain) to an intruder  at least until the system leaves the set of secret states. This notion ...

Detectability in stochastic discrete event systems
(IFAC Secretariat, 2014)In this paper we define and analyze notions of detectability in stochastic discrete event systems (SDES). More specifically, we introduce the notions of Adetectability and AAdetectability which focus on characterizing ...

Article
Detectability in stochastic discrete event systems
(2015)A discrete event system possesses the property of detectability if it allows an observer to perfectly estimate the current state of the system after a finite number of observed symbols, i.e., detectability captures the ...

Conference Object
Initial state opacity in stochastic des
(2013)A nondeterministic finite automaton is initialstate opaque if the membership of its true initial state to a given set of secret states S remains opaque (i.e., uncertain) to an intruder who observes system activity through ...

Conference Object
Opacity formulations and verification in discrete event systems
(Institute of Electrical and Electronics Engineers Inc., 2014)In many emerging security applications, a property of a system, that may reveal important details about its behaviour, needs to be kept secret (opaque) to outside observers (intruders). Motivated by such applications, ...

Opacity verification in stochastic discrete event systems
(2010)Motivated by security and privacy considerations in applications of discrete event systems, various notions of opacity have been introduced. Specifically, a system is said to be currentstate opaque if the entrance of the ...

Probabilistic system opacity in discrete event systems
(Institute of Electrical and Electronics Engineers Inc., 2016)In many emerging security applications, a system designer frequently needs to ensure that a certain property of a given system (that may reveal important details about the system's operation) be kept secret (opaque) to ...

Probabilistic system opacity in discrete event systems
(2018)In many emerging security applications, a system designer frequently needs to ensure that a certain property of a given system (that may reveal important details about the system’s operation) be kept secret (opaque) to ...

Article
Verification of detectability in Probabilistic Finite Automata
(2017)In this paper we analyze state estimation in stochastic discrete event systems (SDES) that can be modeled as probabilistic finite automata (PFAs). For a given PFA, we obtain the necessary and sufficient conditions that ...
