Design of Cross-Domain Transmission Security Control System for Wireless Sensor Big Data in Heterogeneous Environment

摘要:

在异构环境下无线传感大数据受到网络入侵影响，容易出现数据丢包率高且传输效率低的问题，因此设计了异构环境下无线传感大数据跨域传输安全控制系统。根据异构环境下无线传感网络结构，设计由数据采集模块、处理模块和显示模块组成的系统总体结构。选择SY AD 08T型号数据信号采集器，监控现场数据采集显示结果；使用Ryzen 3 2200G型号核心处理器支持自适应动态扩频，执行处理指令；通过控制电路中电压值范围，调节电流强度。软件设计部分利用高维数据空间降维改进算法，借助ELM分类器检测大数据跨域传输入侵情况，利用通信窃听方式添加噪声控制接收端信噪比上限，以此控制跨域传输噪声。融合信道编码纠错与密码流扰乱，限制数据解码时间，阻止非正常渠道窃听。在网络环境和配置清单支持下进行实验验证分析，由实验结果可知，该系统丢包率低于1.5%，大数据传输效率最高为98%，有效增强了大数据跨域传输安全性。

Abstract:

In the heterogeneous environment, wireless sensor big data is affected by network intrusion, which is prone to problems of high data packet loss rate and low transmission efficiency. Therefore, a cross-domain transmission security control system for wireless sensor big data in a heterogeneous environment is designed. According to the structure of the wireless sensor network in a heterogeneous environment, the overall structure of the system composed of data acquisition module, processing module and display module is designed. Select the SY AD 08T model data signal collector to monitor the on-site data acquisition display results; use the Ryzen 3 2200G model core processor to support adaptive dynamic spread spectrum, execute processing instructions; adjust the current intensity by controlling the voltage value range in the circuit. The software design part uses the improved algorithm of high-dimensional data space dimensionality reduction, uses the ELM classifier to detect the intrusion of large data cross-domain transmission, and uses communication eavesdropping to add noise to control the upper limit of the signal-to-noise ratio at the receiving end to control cross-domain transmission noise. Fusion of channel coding error correction and cipher stream disruption limits data decoding time and prevents abnormal channels from eavesdropping. The experimental verification analysis was carried out under the support of the network environment and configuration list. From the experimental results, it can be seen that the system's packet loss rate is less than 1.5%, and the maximum data transmission efficiency is 98%, which effectively enhances the security of large data cross-domain transmission.
