“…Recently, many research works have been performed on authentication protocols/schemes for the V2G network [5], [8], [9], privacy preserving authentication [7] and threshold credit-based incentive mechanism [14], privacy-enhanced data aggregation [15], privacy preserving communication [16], and virtual ring architecture for smart grid privacy [17]. However, various possible attacks in the V2G network are still not well investigated.…”

“…However, the scheme is just a variant of standard DSA algorithm and does not consider the important aspects in the V2G network, such as privacypreservation of vehicle's sensitive information, prevention against various security attacks, and key management for secure communication. Privacy of the users and communication security of the smart grid are studied in [15] where a batchoriented power-usage data aggregation scheme for the smart grid is proposed. However, the scheme discusses a generic adversary model without any security attack scenario, and does not provide mutual authentication.…”

“…We compare our scheme (home, visiting, and centralized V2G networks) only with the schemes presented in [16] and [7]. Others are not comparable since the scheme presented in [15] does not provide mutual authentication and is vulnerable to attacks. The scheme in [5] is not fit to the V2G network, as it does not focus on vehicle behavior and V2G security and privacy features.…”

Abstract-Navigating security and privacy challenges is one of the crucial requirements in the Vehicle-to-Grid (V2G) network. Since Electric Vehicles (EV) need to provide their private information to aggregators/servers when charging/discharging at different charging stations, privacy of the vehicle owners can be compromised if the information is misused, traced, or revealed. In a wide V2G network, where vehicles can move outside of their home network to visiting networks, security and privacy becomes even more challenging due to untrusted entities in the visiting networks. Although some privacy-preserving solutions were proposed in literature to tackle this problem, they do not protect against well-known security attacks and generate a huge overhead. Therefore, we propose a mutual authentication scheme to preserve privacy of the EV's information from aggregators/servers in the home as well as distributed visiting V2G networks. Our scheme, based on a bilinear pairing technique with an accumulator performing batch verification, yields higher system efficiency, defeats various security attacks, and maintains untraceability, forward privacy, and identity anonymity. Performance analysis shows that our scheme, in comparison with existing solutions, generates significantly lower communication and computation overheads in the home and centralized V2G networks, and comparable overheads in the distributed visiting V2G networks.

“…By injecting blinding factors and using Paillier's additive homomorphism encryption scheme [12], Fan et al [17] proposed the first DA scheme for the SG withstanding internal attacks. Compared with related schemes [11,[13][14][15][16], Fan et al's DA scheme [17] could provide better solution of preserving user's privacy in the SG. However, Fan et al's scheme suffers from the key leakage problem because any adversary could extract the user's private key through the public information.…”

Privacy-preserving data aggregation scheme against internal attackers in smart grids

With fast advancements of communication, systems and information technologies, a smart grid (SG) could bring much convenience to users because it could provide a reliable and efficient energy service. The data aggregation (DA) scheme for the SG plays an important role in evaluating information about current energy usage. To achieve the goal of preserving users' privacy, many DA schemes for the SG have been proposed in last decade. However, how to withstand attacks of internal adversaries is not considered in those schemes. To enhance preservation of privacy, Fan et al. proposed a DA scheme for the SG against internal adversaries. In Fan et al.'s DA scheme, blinding factors are used in evaluating information about current energy usage and the aggregator cannot get the consumption information of any individual user. Fan et al. demonstrated that their scheme was secure against various attacks. However, we find that their scheme suffers from the key leakage problem, i.e., the adversary could extract the user's private key through the public information. To overcome such serious weakness, this paper proposes an efficient and privacy-preserving DA scheme for the SG against internal attacks. Analysis shows that the proposed DA scheme not only overcome the key leakage problem in Fan et al.'s DA scheme, but also has better performance.

“…The three schemes are all based on Pallier's homomorphic encryption technology. Fan et al [10] proposed data aggregations scheme based on the subgroup indistinguishability assumption. All the above aggregation schemes are designed for the in-network smart grid devices, and they are used to aggregate individual usage date from different customers.…”

Smart grid aims to improve the reliability, efficiency, and security of the traditional grid, which allows two-way transmission and efficiency-driven response. However, a main concern of this new technique is that the fine-grained metering data may leak the personal privacy information of the customers. Thus, the data aggregation mechanism for privacy protection is required for the meter report protocol in smart grid. In this paper, we propose an efficient privacy-preserving meter report protocol for the isolated smart grid devices. Our protocol consists of an encryption scheme with additively homomorphic property and a linearly homomorphic signature scheme, where the linearly homomorphic signature scheme is suitable for privacy-preserving data aggregation. We also provide security analysis of our protocol in the context of some typical attacks in smart grid. The implementation of our protocol on the Intel Edison platform shows that our protocol is efficient enough for the physical constrained devices, like smart meters.
