调度集中系统数据传输过程中的机密性探讨
Discussion on Confidentiality in Data Transmission Process of Centralized Traffic Control System
摘要
Abstract
Considering the existing network situation of the Centralized Traffic Control(CTC)system and the network security requirements for data confidentiality in the communication and transmission processes,a data encryption technology suitable for the network model of the CTC system is studied.Through research and comparison of VPN encryption technical principles and technologies,dynamic multi-point smart VPN is selected as the network layer encryption technology.Dynamic multi-point smart VPN can achieve the transparent encryption of service systems at the network layer without changing service system configurations.In terms of redundancy capacity,when the core equipment of any node fails,the normal operation of the relevant services will not be affected.The national cryptography dynamic multi-point technical solution can achieve the differentiated setting of access certificates and encryption certificates,which is more secure and reliable than ordinary encryption technologies from other countries.关键词
