电力EPON通信网安全设计

分析电力EPON通信网存在的安全隐患的基础上,对电力EPON通信网的安全机制进行了设计.针对电力EPON通信网的安全隐患,从终端认证、业务隔离、深度检测与防御三个方面对电力EPON通信设备进行安全防护部署.通过EPON通信数据的加密处理和密钥管理,实现OLT与ONU的双向身份认证,确保了电力EPON通信数据的安全.测试结果表明,系统正常工作时,数据传输的上行延时小于2ms,下行延时不超过1ms,完全满足电力系统数据和信息传输的要求.

Design of Security Mechanism for Electric Power EPON Communication Network

In order to ensure the reliable and secure transmission of electric power data and information, on the basis of analyzing the potential safety hazard in electric power EPON communication network, the security mechanism of electric power EPON commu- nication network is designed. According to the potential safety hazard in electric power EPON communication network, the electric power EPON communication devices is deployed with secure defense from three aspects： terminal authentication, business isolation, deep detection and defense. The bidirectional identity authentication between OLT and ONU is realized by encryption processing and key management of EPON communication data, which ensures the security of electric power EPON communication data. The results of testing demonstrate that when the communication system works normally, the up - delay of data transmission is less than 2 micro- second, and the down - delay is not beyond 1 microsecond, which entirely meets the demands of data and information transmission in electric power system.
