摘　　要：共享电源无线网络通信数据加密方法由于难以对缺失信息进行精准聚类,导致在规定时间内加密范围较小。为此,提出基于数据聚类的共享电源无线网络通信数据加密系统。系统硬件主要设计了STM32微处理器和通信器,STM32微处理器的外设结构可以直接与共享电源中的DMA单元关联运行,内部的芯片支持后期升级与拓展,引导ST为STM32微处理器提供固定驱动程序,为数据聚类提供了空间。通信器采用GPRS芯片,在安全方面设计了接收端口与发送端口之间基于串口RS232的TCP连接,支持5G网络环境下的所有射频技术应用,是提高聚类数据效率的基础。利用数据聚类进行数据筛选,设定共享电源无线网络通信数据筛选程序,将聚类信息汇总分别在发送端和接收端进行加密,实现加密软件操作。实验结果表明,加密数据量为50 GB时,正常数据加密时间为24.39 s,存在缺失数据加密时间为24.57 s,加密时间为15 s时,该文方法的加密数据量可达15 GB,表明该文方法能够很好地弥补缺失信息,扩大加密范围。The encryption method of communication data in wireless network of shared power is difficult to accurately cluster the missing information,resulting in a small range of encryption within a specified time.Therefore,this paper proposes a data encryption system based on data clustering for shared power wireless network communication.The system hardware is mainly designed with STM32 microprocessor and communicator.The peripheral structure of STM32 microprocessor can directly communicate with the shared power supply.The DMA unit runs in association,and the internal chip supports later upgrades and expansions.It guides ST to provide fixed drivers for the STM32 microprocessor,providing space for data clustering.The communicator uses a GPRS chip.In terms of security,a serial port RS232-based TCP connection is designed between the receiving port and the sending port.It supports all radio frequency technology applications in the 5G network environment and is the basis for improving the efficiency of clustering data.Use data clustering for data screening,set up a shared power wireless network communication data screening program,summarize the clustering information and encrypt it at the sending end and the receiving end respectively,and realize the encryption software operation.Experimental results show that when the amount of encrypted data is 50 GB,the normal data encryption time is 24.39 s,and when there is missing data encryption time is 24.57 s.When the encryption time is 15 s,the amount of encrypted data in this paper can reach 15 GB,indicating that the proposed method can make up for missing information well and expand the encryption range.
