摘要 针对智能电网基于实时电价的计费过程中有大量实时用电数据需要交互和计算,且隐私数据保护不够完善的安全问题,提出了一种基于隐私保护的实时电价计费方案。利用加法同态加密、混合乘法同态加密等技术,保证了实时用电数据在通信、数据聚合、电费计算和账单验证过程中的安全;同时,通过聚合签名技术减少了数据认证过程中的开销。通过对所述方案进行安全性分析和性能分析,表明该方案具有很好的安全性,且性能较高。

英文摘要 Aiming at security problems in smart grid, this paper proposed a secure billing scheme based on privacy protection to interact and calculated a large amount of privacy data and improved the privacy data protection. Its additive homomorphic encryption and mixed multiplication homomorphic encryption ensure the security of real-time power data in communication, data aggregation, electricity expenditure calculation and billing verification. Meanwhile, the aggregation signature technology reduced the overhead of data authentication process. The security analysis and performance analysis of the proposed scheme show that the scheme has good security and high performance.
