摘要
合法侦听是以保障信息安全为目的的一种合法行为,是关系到国家安全的重要信息技术,在我国研究刚刚起步,尤其是IP网络的合法侦听尚属空白。文章首先阐述了合法侦听的网络结构和控制流程,分析了侦听执行网络和侦听对象网络之间的关系。研究了合法侦听的功能实现,描述了基于协议分层模型的内部侦听功能结构。深入讨论合法侦听接口,给出了接口信息内容和基本结构单元。
LI （LawfuI Interception） is a IegaI warrant interception aimed at network security. It is an important information technology related to the security of the country, and its research is underway in domestic, especially it has been bIank on IP network. The paper firstIy investigated the network architecture and the controI procedure of LI, and the reIationship between the interceptions perform network and the interception object network are anaIyzed. Afterwards, the paper investigated the function impIementation, and described the architecture of internal interception function based on the OSI, FinalIy, a thorough discussion on the handover interface was made, and the interface information and the basic architecture units were brought out.
