TL;DR: The proposed testbed of the cyber‐power system consists of power system simulation, substation automation, and the SCADA system, and scenarios for substation cyber security intrusions and anomaly detection concepts have been proposed.
Abstract: The proposed testbed of the cyber‐power system consists of power system simulation, substation automation, and the SCADA system. Scenarios for substation cyber security intrusions and anomaly detection concepts have been proposed. An attack tree method can be used to identify vulnerable substations and intrusions through remote access points. Specific substation vulnerability scenarios have been tested. Temporal anomaly is determined by data and information acquired at different time points. This is a metric to determine the anomaly between two snapshots. In a distributed intrusion detection algorithm, distributed agents are trained with a large number of scenarios and intended for real‐time applications. In a distributed environment, if an anomaly is detected by one agent, it is able to distribute critical information to other agents in the network.

TL;DR: This article designs capacity-centric FiWi broadband access networks enhanced with edge computing as well as resulting fiber backhaul sharing and computation offloading capabilities and proposes a TDMA based polling scheme for resource management to guarantee low end-to-end latency.
Abstract: Recently, edge computing has emerged as a promising computing paradigm to meet stringent quality-of-service requirements of an increasing number of latency-sensitive applications. The core principle of edge computing is to bring the capability of cloud computing in close proximity to mobile devices, sensors, actuators, connected things and end users, thereby supporting various types of services and applications at the network edge. In this article, we design capacity-centric FiWi broadband access networks enhanced with edge computing as well as resulting fiber backhaul sharing and computation offloading capabilities. More specifically, we introduce the concept of FiWi enhanced two-level edge computing at the access edge cloud and metro edge cloud. To guarantee low end-to-end latency, we propose a TDMA based polling scheme for resource management. Furthermore, given the vital importance of experimentally demonstrating the potential and practical limitations of edge computing, we develop an experimental testbed for edge computing across converged FiWi broadband access networks. The proof-ofconcept demonstration of the testbed is studied in terms of response time and response time efficiency of both edge clouds, including their respective energy consumption.

TL;DR: This paper proposes a more cost-effective alternative of implementing SDN testbed with Open vSwitch (OVS), based on the Raspberry-Pi that is a low-cost embedded Linux machine and proves that its maximum network throughput shows almost the same performance compared to the NetFPGA-1G.
Abstract: OpenFlow is the first standard interface for realizing Software-Defined Networking (SDN) that can decouple the data and control plane to provide scalable network management. To validate the performance and features of the OpenFlow standard, many researchers have utilized specialized hardware network devices such as NetFPGA. However, these devices are not suitable for implementing a small-scale SDN testbed due to high cost, complexity, and specialized programming languages. The well-known SDN emulator, Mininet[l], is also widely utilized but it is not enough to support network dynamicity and the performance of the virtualized hosts. In this paper, we suggest a more cost-effective alternative of implementing SDN testbed with Open vSwitch (OVS), based on the Raspberry-Pi that is a low-cost embedded Linux machine. We validate our testbed with the OpenFlow specification 1.0 and prove that its maximum network throughput shows almost the same performance compared to the NetFPGA-1G.
