Signaling Games for Log-Concave Distributions: Number of Bins and Properties of Equilibria
Kazikli, Ertan; Sarıtaş, Serkan; GEZİCİ, Sinan; Linder, Tamas; Yuksel, Serdar (2022-03-01)
We investigate the equilibrium behavior for the decentralized cheap talk problem for real random variables and quadratic cost criteria in which an encoder and a decoder have misaligned objective functions. In prior work, i...
Privacy Signaling Games with Binary Alphabets
Stavrou, Photios A.; Sarıtaş, Serkan; Skoglund, Mikael (2022-01-01)
In this paper, we consider a privacy signaling game problem for binary alphabets and single-bit transmission where a transmitter has a pair of messages, one of which is a casual message that needs to be conveyed, whereas t...
Adversarial Attacks on CFO-Based Continuous Physical Layer Authentication: A Game Theoretic Study
Sarıtaş, Serkan; Thobaben, Ragnar; Sandberg, Henrik; Dan, Gyorgy (2021-06-01)
5G and beyond 5G low power wireless networks make Internet of Things (IoT) and Cyber-Physical Systems (CPS) applications capable of serving massive amounts of devices and machines. Due to the broadcast nature of wireless n...
Quadratic Signaling Games with Channel Combining Ratio
Sarıtaş, Serkan; Thobaben, Ragnar; Skoglund, Mikael (2021-01-01)
In this study, Nash and Stackelberg equilibria of single-stage and multi-stage quadratic signaling games between an encoder and a decoder are investigated. In the considered setup, the objective functions of the encoder an...
Asymptotic Security of Control Systems by Covert Reaction: Repeated Signaling Game with Undisclosed Belief
Sasahara, Hampei; Sarıtaş, Serkan; Sandberg, Henrik (2020-12-14)
This study investigates the relationship between resilience of control systems to attacks and the information available to malicious attackers. Specifically, it is shown that control systems are guaranteed to be secure in ...
A Nash equilibrium-based moving target defense against stealthy sensor attacks
Umsonst, David; Sarıtaş, Serkan; Sandberg, Henrik (2020-12-14)
© 2020 IEEE.This paper investigates a moving target defense strategy based on detector threshold switching against stealthy sensor attacks. We model the interactions between the attacker and the defender as a game. While t...
Dynamic signaling games with quadratic criteria under Nash and Stackelberg equilibria
Yuksel, Serdar; Sarıtaş, Serkan; Gezici, Sinan (2020-05-01)
This paper considers dynamic (multi-stage) signaling games involving an encoder and a decoder who have subjective models on the cost functions. We consider both Nash (simultaneous-move) and Stackelberg (leader-follower) eq...
Passive Fault-tolerant Estimation under Strategic Adversarial Bias
Sarıtaş, Serkan; Sandberg, Henrik (2020-01-01)
This paper is concerned with the problem of fault-tolerant estimation in cyber-physical systems. In cyber-physical systems, such as critical infrastructures, networked embedded sensors are widely used for monitoring and ca...
Hypothesis Testing Under Subjective Priors and Costs as a Signaling Game
Sarıtaş, Serkan; Yuksel, Serdar (2019-10-01)
Many communication, sensor network, and networked control problems involve agents (decision makers) which have either misaligned objective functions or subjective probabilistic models. In the context of such setups, we con...
Adversarial Attacks on Continuous Authentication Security: A Dynamic Game Approach
Sarıtaş, Serkan; Sandberg, Henrik; Dan, Gyorgy (2019-01-01)
Identity theft through phishing and session hijacking attacks has become a major attack vector in recent years, and is expected to become more frequent due to the pervasive use of mobile devices. Continuous authentication ...
