摘要:

用户电力消费数据安全是智能电网实施过程中需要解决的问题。针对智能电表中高频数据与低频数据安全性要求不同,文章提出一种基于虚拟环架构的电力用户隐私保护方法。首先使用NTRU加密系统对用户请求数据进行加密,然后建立高频数据与低频数据传输通路。低频数据在环外传输,高频数据在环内实现匿名性,并使用动态交易令牌聚合用户请求。这种隐私保护方法保证了电网操作与账单计算等功能的有效性,实现了用户电力消费数据隐私保护的完整性,提高了通信效率。

Abstract:

The security of user power consumption data is a problem that needs to be solved in the implementation of smart grid. For the security requirements of high-frequency data and low-frequency data are different in the smart meters, this paper proposes a privacy protection method for power users based on virtual ring architecture. First, using the NTRU encryption system to encrypt the user request data, then constructing the transmission paths of high-frequency data and low-frequency data. Low-frequency data is transmitted outside the ring. High-frequency data is anonymized in the ring, and user requests are aggregated with dynamic transaction token (DTT) . The privacy protection method guarantees the validity of grid operation and bill calculation, realizes the integrity of privacy protection of user power consumption data ,and improves the communication efficiency.

Key words: high frequency data, low frequency data, virtual ring architecture, dynamic transaction token, privacy
