“…In prior work [17], our research showed that the hub-andspoke communications network establishes the necessary connectivity to maximize the trust payoff between a convoy leader and its followers to move together in a column formation. In essence, the convoy leader serves as the trusted third-party for all of its followers in the convoy, thereby allowing the convoy to maximize its trust synergy while minimizing its trust liability.…”

This paper describes a trust-based vehicle controller that can be tuned to ensure decentralized string stability in a convoy. The controller leverages the RoboTrust algorithm to mitigate risks associated with trust-based vulnerabilities, such as cyber attacks, poor decisions, and malfunctions. In our scenario, we simulate a simple convoy mission in which twelve vehicles move together between waypoints, stopping at each waypoint before proceeding. We examine the decisions of the convoy leader at each waypoint and show how its behaviors can introduce spacing errors throughout the convoy column. We then show how the trust-based controller can modify the leader's behaviors and minimize the effect of error propagation and amplification in the convoy.

“…Trust-based methods have been investigated for not only cyber-security but also general problems where some of the subsystems may be untrustworthy. References [143]- [145] have used a multi-agent approach in order to improve overall resilience. This strategy is equivalent to redundancy-based approaches in graphs and is based on the assumption that if the number of attacks is sufficiently small, correct information can flow through the paths formed by trusted nodes.…”

The comprehensive integration of instrumentation, communication, and control into physical systems has led to the study of Cyber-Physical Systems (CPS), a field that has recently garnered increased attention. A key concern that is ubiquitous in CPS is a need to ensure security in the face of cyber attacks. In this paper, we carry out a survey of systems and control methods that have been proposed for the security of CPS. We classify these methods into three categories based on the type of defense proposed against the cyberattacks: prevention, resilience, and detection & isolation. A unified threat assessment metric is proposed in order to evaluate how CPS security is achieved in each of these three cases. Also surveyed are risk assessment tools and the effect of network topology on CPS security. An emphasis has been placed on power and transportation applications in the overall survey. Index Terms-cyber-physical systems, resilient control I. INTRODUCTION Motivated by concerns about sustainability, efficiency, and resiliency, several sectors including energy, transportation, water, and healthcare systems have witnessed significant advances in instrumentation, monitoring, and automation over the past decade. The resulting integration of information, communication, and computation with physically engineered systems demands a detailed investigation into the analysis and synthesis of Cyber-Physical Systems (CPS) so as to realize the desired performance metrics of efficiency, sustainability, and safety. The extensive and intricate presence of cyber components also introduces a vulnerability of unwanted access to these systems. The available communication technologies, referred to as SCADA (Supervisory Control and Data Acquisition), are witnessing significant advances, triggering a shift from protected, closed, and wired networks to open and wireless networks which, as a side effect, are more vulnerable to outside interference.

Multiagent Resource Allocation (MARA) is a field to find out solutions that distribute a set of resources among agents. Heretofore, lots of utility-and reputationbased approaches have been proposed. In this paper, we develop a preference-based resource reservation approach for resource allocation in a system that consists of entirely selfless agents. Preference, defined as the satisfaction of required resources, has a crucial impact on resource allocation. The importance degree is also adopted to represent the extent to which a particular attribute is needed. In the system, agents communicate with semi-local friends to exchange information as well as reserving resources. Finally, a confirmation or cancelation message is sent to obtain or release the reserved resources. Numerical examples are given to show the rationality and effectiveness of the proposed method.
