摘　　要：随着大数据、云计算、物联网等移动互联网技术的不断发展,新型数字技术与传统电力技术深度融合的新型电力系统成为推进能源电力绿色转型的有效手段,而新型数字技术的引入也对能源电力安全提出了新的要求,电力物联网中边端数据传输作为新型电力系统底层数据收集架构的重要环节,保障其安全稳定显得尤为重要。在传统的电力物联网的数据传输中,无线通信技术易受到信道互易性和噪声等因素的影响,造成密钥一致性和生成率较差。针对这一问题,提出了一种面向新型电力系统物联网信息传输安全的可靠密钥生成方法。一方面,动态调整信道探测过程中的训练序列长度以提高密钥一致性;另一方面,使用迭代量化方法量化RSS测量值提升密钥生成率。仿真结果显示,本方法可有效提升密钥一致性及生成率,防范第三方窃听,为电力物联网边端数据传输提供安全保障。With the constant development of big data,cloud computing,Internet of Things and other mobile internet technologies,the new power system with the deep integration of new digital technology and traditional power technology has become an effective means to promote the green transformation of energy and electricity.The introduction of new digital technology also puts forward new requirements for security of energy and electricity. As the edge data transmission in Internet of Things in the power system plays an important role in the underlying data collection architecture of the new power system,it is particularly important to ensure its security and stability. In the traditional data transfer in Internet of Things of the power system,wireless communication technology is susceptible to channel reciprocity,noise and other factors,which lead to the poor key consistency and generation rate.In order to solve this problem,a reliable key generation method for information transmission security in Internet of Things of the new power system is put forward. On the one hand,the length of the training sequence in the channel probing process is dynamically adjusted to improve key consistency;on the other hand,the iterative quantization method is used to quantify RSS measurements to improve the key generation rate. Simulation results show that,this method can effectively improve the key consistency and generation rate,guard against third party eavesdropping,which provides security guarantee for edge data transmission in Internet of Things of the power system.
