基于电力通信的密钥分发

Key Distribution based on Power Communication

从电力线通信覆盖范围、连接传输和使用特点入手,对各种通信介质成本、运行费用、部署周期、维护工作和通信速率等进行分析比较。针对目前各式安全设备信道特点和应用场景,提出了基于电力通信方式的密钥在交流、直流和交直流混合的密钥分发系统模型。在此基础上,详细介绍在交流、直流和交直流混合等情形下模块的详细设计和系统测试情况,最后论述基于电力通信密钥分发未来在区域性或者全国性应用可能。

Starting from the characteristics of power-line communication coverage,connection,transmission and use,the prime cost,operating expense,deployment cycle,maintenance work and communication speed of various communication media are analyzed and compared.In view of the channel characteristics and application scenarios of various security devices,the model of key distribution system based on power communication is proposed.Based on this,the detailed design and system test of the modules in AC,DC and AC/DC mixing are described in detail.Finally,the regional and national application possibility of key distribution based on power-line communication in the future is discussed.
