GTP隧道管理消息状态分析

Status Analysis of GTP Tunnel Information Management

为解决3G网络本身的安全问题,在了解GTP协议结构的基础上,设计出GTP隧道管理消息的状态机。通过对隧道管理消息的状态进行跟踪分析,阐明防火墙对GTP包状态的监测原理,为针对GTP协议攻击的防御研究提供了新的研究视角和分析途径。

With the popularization of 3G mobile network, solutions to possible security problems is becoming more and more important. This paper, based on GTP protocol, designed a state machine for GTP tunnel information management to make a trace analysis, and illustrated how firewall monitors GTP package status, all in an effort to bring a new perspective and an approach to the research on GTP attack defense.
