“…Table 3 presents the comparative analysis in terms of key size and total number of keys stored. In the proposed scheme, if there are n IEDs in the network, each one stores only K i-auth , K IED /PK IED and K g keys while [7] needs to store k c , two KS keys, and 2(n − 1) session secret keys and thus have a high communication overhead specially in the broadcast scenario. In order to calculate the packetization delay t S , we considered only the encryption and authentication process while t R is the time to verify the messages at the receiver.…”

Abstract:Microgrids play an important role in today's power systems as the distributed generation is becoming increasingly common. They can operate in two possible modes: (i) standalone and (ii) grid-connected. The transitional state from standalone to grid-connected mode is very critical and requires the microgrid to be synchronized with the main grid. Thus, secure, reliable and trustworthy control and communication is utmost necessary to prevent out-of-sync connection which could severely damage the microgrid and/or the main grid. Existing solutions consume more resources and take long time to establish a secure connection. The objective of the proposed work is to reduce the connection establishment time by using efficient computational algorithms and save the resources. This paper proposes a secure authentication and key establishment mechanism for ensuring safe operation and control of the microgrids. The proposed approach uses the concept of Elgamal with slight modification. Private key of the sender is used instead of a random number. The proposed modification ensures the non repudiation. This paper also presents a system threat model along with security network architecture and evaluates the performance of proposed algorithm in protecting microgrid communication against man in the middle attacks and replay attacks that could delay the packets to damage the system and need to be detected. Mathematical modeling and simulation results show that the proposed algorithm performs better than the existing protocols in terms of connection establishment, resource consumption and security level.

“…The security must be fully considered from the commencement of data collection up to their reception at the control and management center. Intensive review of the previous works shows that the security of SG is a very interesting topic and so many papers have discussed this challenging requirement. To have a taxonomy of these works, we can mention the works that have considered the key management in SG, the many works that have paid attention to false data injection attack, the miscellaneous works that have proposed privacy‐preserving schemes, and the few works that have taken the advantage of lattice‐based cryptosystem into account …”

Summary In smart grid, bidirectional communications between the smart meters and control center are subject to several security challenges. Since the smart meters have limited storage space and processing capability, the suggested communication scheme not only must consider the security requirements but also should put the least possible burden on the smart meters' resources. In 2014, an interesting communication scheme has been proposed for the secure consumption reports transmission of the smart meters to the neighbor gateways. In this paper, we first show that this scheme is vulnerable to the smart meter's memory modification, pollution, and denial of service attacks; then, we propose an authenticated communication scheme, which not only is secure against the aforementioned attacks, but also is much more efficient in terms of storage space, communication overhead, and computational complexity. Moreover, our scheme also presents the details of control messages transmission from the neighborhood gateways to the smart meters. Our comparative analysis with several recently published schemes indicates that the proposed scheme is more suitable than the previous ones. More significantly, our realistic implementation on ATmega2560, as a suitable candidate to be used for the smart meters, confirms our claim.

“…In contrast to AC distribution systems, DC MGs provide significant installation, operation and maintenance flexibility due to high penetration of renewable DERs that are interfaced to the DC infrastructure through power electronic converters [1], [2]. Specifically, the extensive use of power electronic converters provides for implementation of advanced control and optimization mechanisms in DC MGs, where the feedback loop is typically closed via external communication network [3].The ongoing trend emphasizes the importance of the security of the control system, particularly the security of the feedback loop, and raises concerns regarding the adequacy of existing communication technologies for the security challenges of the evolving DC MG ecosystem [4].

Abstract-We propose a novel framework for secure and reliable authentication of Distributed Energy Resources to the centralized secondary/tertiary control system of a DC MicroGrid (MG), networked using the IEEE 802.11 wireless interface. The key idea is to perform the authentication using power talka powerline communication technique executed by the primary control loops of the power electronic converters. In addition, the scheme also promotes direct and active participation of the control system in the authentication process, a feature not commonly encountered in current networked control systems for MicroGrids. The PLECS R -based simulations verifies the viability of the proposed solution.
