IP网络的侦听研究

Lawful Interception of IP Network

Internet网络的广泛应用使得对IP网络上流动的信息进行合法侦听越来越重要,然而IP网络的合法侦听相对来说更加复杂和不成熟。根据ETSI有关合法侦听标准,从合法侦听的角度分析了IP网络数据传输模型,给出了不同传输模型下的侦听点的设置。考虑到侦听数据传输的有效性和安全性,对于IP网络中侦听数据的传送提出具体要求,并且给出了侦听数据在网络中的传递模型。

Internet interception is becoming more important because people depend more on Interact. However, Lawful Interception of the Internet is both more difficult and much less mature. From the point of view of lawful interception, the paper analyses the data delivery mode and introduces how to set the intercept access point （IAP） by the method of the network connection, which baaed on the interception standard of ETSI. Considering both the validity and security of lawful interception, we also present the requirement for delivery intercepted data and propose the delivery mode of intercepted data.
