“…There are quite a few key management schemes designed especially for SCADA: [4,8,6,17,7,12]; however, they are not adequate because they do not take into account the rest of the Smart Grid's components. An overview of each of these proposals is presented in [23].…”

“…On the other hand, upgrading such a large and complex system, like the Smart Grid, could introduce new vulnerabilities and expose it to common cyberthreats, as have been described in relevant survey articles [23,2,28]. There are numerous possible attacks against the Smart Grid, for example attacks against the availability of the utility's control systems with varied consequences ranging from data theft to loss of human lives, against the smart meters leading to incorrect billing and personal data theft, and against the communication protocols that support the operation of the Smart Grid.…”

“…However, already proposed key management schemes come with several limitations. According to [23], some of the existing key management schemes are for Supervisory Control And Data Acquisition (SCADA) systems. SCADA are decision making systems used to control and monitor physical processes remotely; they provide the connection between the cyber and the physical world and typically are closed and proprietary.…”

Abstract. As Smart Grid deployments emerge around the world, their protection against cyberattacks becomes more crucial. Before protective measures are put into place, one of the main factors to be considered is key management. Smart Grid poses special requirements compared to traditional networks; however, the review of previous work reveals that existing schemes are not complete. Here we propose a scalable and distributed key management scheme for the Smart Grid based on the Web-of-Trust concept. Our proposal is build on top of a Distributed Hash Table for efficient lookups of trust relationships. The target of this scheme is to create a key management system for the Smart Grid without the need of an always available Trusted Third Party. The underlying Distributed Hash Table can be further utilised as an infrastructure to build other Smart Grid services on top of it, like secure and/or anonymous aggregation, billing, etc.

“…In this paper, we consider four broad categories of cyber-attacks in the smart grid communication: interrupting availability, violating integrity, compromising confidentiality, and compromising privacy [32,51]. Attacks interrupting availability include DoS attack, replay attack, and delay, block or corrupt the communication in the SG.…”

“…In power communication networks, such as smart grid, reliability, security, and real-time message delivery have higher priorities than providing high throughput. Therefore, latency requirement is much more important in smart grid system [32]. The communication latency needed for the transmission system protection is in the order of a few milliseconds [33] and authentication time varies up to few seconds [1].…”

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.
