分布式能源der的特点是采用小型发电技术来增强传统电力系统，因此被大力鼓励与智能电网相结合，并且最近提出了许多交易策略来支持新兴智能电网营销中的能源拍卖。然而，很少有人考虑能源交易的安全方面，如隐私保护、出价完整性和预过滤能力。本文针对新兴智能电网营销中的拍卖SESA，提出了一种高效的可搜索加密方案。具体而言，SESA使用公钥加密和关键字搜索技术，使能源卖家（如der）能够查询合适的出价，同时保护能源买家的隐私。此外，为了方便卖方查询投标的详细信息，我们还建议对SESA进行扩展，以支持连接关键词搜索。安全性分析表明，所提出的SESA及其扩展能够实现数据和关键字的保密性、投标完整性和陷门不可伪造性。仿真结果还表明，与现有的可搜索加密方法相比，SESA及其扩展具有更小的计算量和通信开销。版权所有©2013 John Wiley & Sons， Ltd
Distributed energy resources DERs, which are characterized by small-scale power generation technologies to provide an enhancement of the traditional power system, have been strongly encouraged to be integrated into the smart grid, and numerous trading strategies have recently been proposed to support the energy auction in the emerging smart grid marketing. However, few of them consider the security aspects of energy trading, such as privacy preservation, bid integrity, and pre-filtering ability. In this paper, we propose an efficient searchable encryption scheme for auction SESA in emerging smart grid marketing. Specifically, SESA uses a public key encryption with keyword search technique to enable the energy sellers e.g., DERs to inquire suitable bids while preserving the privacy of the energy buyers. Additionally, to facilitate the seller to search for detailed information of the bids, we also propose an extension of SESA to support conjunctive keywords search. Security analysis demonstrates that the proposed SESA and its extension can achieve data and keyword privacy, bid integrity and trapdoor unforgeability. Simulation results also show that both SESA and its extension have less computation and communication overhead than the existing searchable encryption approaches.
