During the development and expansion of Internet of Things (IoT), main challenges needing to be addressed are the heterogeneity, interoperability, scalability, flexibility and security of IoT applications. In this paper, we view IoT as a large-scale distributed cyber-physical-social complex network. From that perspective, the above challenges are analyzed. Then, we propose a distributed multi-agent...
Critical infrastructures like smart grid and smart transportations are large-scale distributed CPSs and cyber-physical security is pivotal to their safety and security. Efficient security assessment can help administrators to protect CINs effectively and we propose a universal quantitative cyber-physical security assessment methodology which is based on cyber-physical dependence analyses. For given...
In wireless ad hoc networks (WANETs), collaboration among nodes is usually inefficient and the network is vulnerable to various attacks. Although some intrusion detection systems (IDSs) and reputation strategies have been proposed to enhance the network's robustness, the significant power consumption they cause will reduce the networks' lifetime. In this paper, we propose a power-efficient mechanism...
In power system, state estimation is the basis of protecting and controlling the power grid. However, attackers can interfere the normal state estimating processes by strategically altering certain measurements through false data injection (FDI) attack. To address this problem, a typical solution is deploying a large amount of phasor measurement units (PMUs) at substations with necessary protection...
