摘　　要：为避免智能配电终端受到攻击,保障信息接入行为的安全性,针对5G通信环境下的智能配电终端零信任安全接入技术展开研究。在5G通信架构中,构造完整的Polar码定义模板,再根据滑窗编码时隙参数的取值范围,实现对智能配电终端传输数据的安全性编码处理。然后,以零信任传输协议为基础,定义与Scoket安全指令相关的信息文本,通过交叉编译的方式,将数据样本传输至配电终端的既定主机中。实验结果表明,5G通信架构提供了更加稳定的数据传输环境,单位时间内信息样本累积总量不会超过5.0×10^(13)bit,可以避免过量存储的数据信息对智能配电终端造成攻击,有效保障了信息接入行为的执行安全性;应用该技术后,终端与5G网络之间的通信延迟时间仅由10.0 ms增加至26.4 ms,时效性更强,更有助于实现实时接入响应和快速接入交互,满足实际应用需求。In order to avoid attacks on intelligent distribution terminals and ensure the security of information access behavior,the zero-trust security access technology of intelligent distribution terminals under 5G communication environment is studied.In the 5G communication architecture,a complete polar code definition template is constructed,and then according to the value range of the sliding window coding slot parameter,the security coding processing of the data transmitted by the intelligent distribution terminal is realized.Then,based on the zero trust transmission protocol,the information text related to the Scoket security instructions is defined,and the data samples are transmitted to the established host of the distribution terminal through cross compilation.The experimental results show that the 5G communication architecture provides a more stable data transmission environment,and the cumulative total amount of information samples per unit time will not exceed 5.0×10^(13) bit can avoid the attack of the intelligent distribution terminal caused by excessive stored data information,effectively guarantee the execution security of information access behavior;After applying this technology,the communication delay time between the terminal and the 5G network only increased from 10.0 ms to 26.4 ms,which has stronger timeliness and is more conducive to achieving real-time access response and fast access interaction,meeting practical application needs.
