“…In certain cases (such as IEC 61850 Protection Class 2/3), multicast messages in the transmission substation network should be delivered within 4 ms as mentioned by Wang et al [34] and Khurana et al [35]. Since several mutual authentications must be performed among various SG entities in a distributed manner, the protocol execution time and the end-to-end delay are critical in the SG system.…”

Abstract:The smart grid (SG) is a promising platform for providing more reliable, efficient, and cost effective electricity to the consumers in a secure manner. Numerous initiatives across the globe are taken by both industry and academia in order to compile various security issues in the smart grid network. Unfortunately, there is no impactful survey paper available in the literature on authentications in the smart grid network. Therefore, this paper addresses the required objectives of an authentication protocol in the smart grid network along with the focus on mutual authentication, access control, and secure integration among different SG components. We review the existing authentication protocols, and analyze mutual authentication, privacy, trust, integrity, and confidentiality of communicating information in the smart grid network. We review authentications between the communicated entities in the smart grid, such as smart appliance, smart meter, energy provider, control center (CC), and home/building/neighborhood area network gateways (GW). We also review the existing authentication schemes for the vehicle-to-grid (V2G) communication network along with various available secure integration and access control schemes. We also discuss the importance of the mutual authentication among SG entities while providing confidentiality and privacy preservation, seamless integration, and required access control with lower overhead, cost, and delay. This paper will help to provide a better understanding of current authentication, authorization, and secure integration issues in the smart grid network and directions to create interest among researchers to further explore these promising areas.

“…Experimental results show that a staff can manage certificates of approximately 1000 users. For example, if an electrical company has 5.5 million smart meters, it will require 5,500 employees to manage these digital certificates [2]. Therefore, manpower and cost are high, and processing cycle is long.…”

Advanced metering infrastructure (AMI) is the core component in smart grid. Moreover, two-way communication between the user and the power utility is realized through AMI. Composition of AMI is described. AMI security requirements are illustrated. The threats on the smart meters, communications network, and data collector are analyzed, respectively. Passive and active defenses are investigated. For the passive defense, the traditional encryption technology has low key transportation security, while the public key infrastructure (PKI) used in the whole smart grid has high cost and long computation time and current ID-based authentication mechanism does not offer mutual authentication between smart meter and smart device. When intrusion detection system (IDS) is deployed on AMI key nodes, it is possible to meet the cost effectiveness and computational efficiency and to make up for the passive security policy.

“…Nowadays, technologies such as sensor networks, smart systems, cyberphysical systems (CPS), and Internet of Things (IoT) depend on small building blocks like sensors, actuators, measuring instruments, and smart devices. These building blocks also become system entities and can require specific authentication mechanisms, as evidenced in applications related to manufacturing [5], transportation [6][7][8], energy management [9,10], smart cities and smart homes [11], and electronic healthcare [12], among others. On the other hand, the same ubiquitous components also introduce a new asset: the physical context information amount, resulting from the integration of physical processes and information technologies [3,13].…”

Modern systems are increasingly dependent on the integration of physical processes and information technologies. This trend is remarkable in applications involving sensor networks, cyberphysical systems, and Internet of Things. Despite its complexity, such integration results in physical context information that can be used to improve security, especially authentication. In this paper, we show that entities sharing the same physical context can use it for establishing a secure communication channel and protecting each other against external attacks. We present such approach proposing a theoretical model for generating unique bitstreams. Two different protocols are suggested. Each one is evaluated using probabilistic analysis and simulation. In the end, we implement the authentication mechanism in a case study using networks radio signal as physical event generator. The results demonstrate the performance of each of the protocols and their suitability for applications in real world.
