LTE传输安全组网技术及规划要点

摘要

在LTE网络中，eNodeB回传采用IP分组承载传送网。IP网络除了简单灵活、扁平化、完全开放等特点外，还使承载的业务面临各种信息安全问题。通过详细分析802.1x、IPSec、SSL和PKI等传输安全关键技术，提出了不同层次的传输安全保护组网建议，以解决eNodeB与EPC核心网之间的通信安全问题。%The eNodeB uses IP packet transport network to return in LTE networks. IP network is simple and flexible, flattening and completely open, however, it also makes the carrying business face many security problems. By analyzing some transmission security technologies, such as 802.1x, IPSec, SSL and PKI, some networking suggestions about protecting the transmission security with different levels are provided to solve communication security problems between eNodeB and EPC core network.
