摘要
IP合法侦听是一种针对被怀疑的IP网络用户或业务进行监听的手段,它通过向网络运营商/接入提供商/服务提供商发出侦听命令,并由它们提供所侦听对象的通信内容和相关信息来完成。介绍了IP合法侦听技术的引入,详细讨论了各种情况下侦听点的选择和侦听信息的捕获,具体分析了涉及安全性问题的侦听内容的传送技术。
The lawful interception on IP network is a method of information security technology aiming at monitoring the suspicious users or services. It is accomplished by sending the request for intercepting to the involved NWO/AP/SvP who will in turn bring the Intercept related information and the contents of communication of (intercepted) object back. Firstly, this paper gives an introduction to the technique for lawful interception on IP. Then the selection of intercepting point in all connection modes and the capture of the incepted data's are discussed in great detail. Finally, the paper analyses the technique of intercepted results' transmitting relating to the security.
