摘　　要：针对目前隐私保护数据聚合方案的功能不够完善,不足以满足日益丰富的应用需求问题,提出了一个支持多功能的V2G网络隐私保护数据聚合(MFPDA)方案。基于BGN、BLS、Shamir密码共享等密码算法,以及雾计算和联盟链技术,将支持容错、抵抗内部攻击、批量签名验证、不需要可信第三方和多种聚合函数等多个安全功能纳入一个隐私保护数据聚合方案中。安全性分析表明,所提方案满足数据聚合的安全性、隐私性和可靠性。性能评估表明,雾计算的引入能显著减少控制中心的计算开销,减少率可达66.6%;对联盟链的改进能有效减少系统的通信和存储开销,减少率分别可达16.7%和24.9%。In view of the problem that the functions of the current privacy protection data aggregation scheme were insufficient to meet the increasingly rich application requirements,a multi-function supported privacy protection data aggregation(MFPDA)scheme for V2G network was proposed.By using cryptographic algorithms such as BGN,BLS,and Shamir’s secret sharing,as well as fog computing and consortium blockchain technology,multiple security functions like fault tolerance,resistance to internal attacks,batch signature verification,no need for trusted third parties,and multiple aggregation functions were integrated into one privacy protection data aggregation scheme.Security analysis shows that the proposed scheme can protect data aggregation’s security,privacy and reliability.The performance evaluation shows that the introduction of fog computing can significantly reduce the computing overhead of the control center,and the reduction rate can be as high as 66.6%;the improvement of the consortium blockchain can effectively reduce the communication and storage overhead of the system,and the reduction rate can reach 16.7%and 24.9%respectively.
