Aggregated-Proofs Based Privacy-Preserving Authentication for V2G Networks in the Smart Grid

摘要: Vehicle-to-grid (V2G) as an essential network component of smart grid, provides services by periodically collecting the charging status a battery vehicle (BV). A BV is normally associated with default interest group (e.g., power grid operator). When accesses its or communication point, it works in home mode. The may move around and temporarily access other aggregators, then visiting In this paper, we first identify that, for aggregator, BVs have different security challenges when they work modes. Then, propose aggregated-proofs based privacy-preserving authentication scheme (AP3A) to achieve simultaneous identification secure working mode BVs. AP3A, are differentiated into either mode, multiple can be simultaneously authenticated aggregator conserve resources. addition, aggregated pseudo-status variation presented realize that BVs' collected whole without revealing any individual privacy. We perform comprehensive analysis on proposed scheme, including attack analysis, performance analysis. It shown AP3A resist major attacks protection privacy preservation, efficient approach V2G networks.
