Embodiment Construction

[0029] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Figure 3A This is the first structural embodiment of the IP network lawful interception system provided by the present invention. It includes a user terminal 31, a network access device 32, an authentication server 34, and a legal interception facility 33 (specifically, it may include a legal interception management device LIAF and a legal enforcement monitoring device LEMF). Among them, the user terminal 31, as a related device used by the user to communicate, is controlled by the user; the network access device 32 is used to connect the user terminal and the connecting device leading to other networks, which is controlled by the network access provider. (NAP) provides, directly connected to the user terminal, according to the technology and configuration it adopts, through its internal internal interception function (IIF), data c...

Abstract

The invention provides a method and a device for realizing internet lawful interception, wherein a lawful interception facility configures interception management information needing interception to a network access management apparatus; the network access management apparatus transmits the interception management information to a network access apparatus where a target user is located when the target user authenticates network access or requests network resources; and the network access apparatus intercepts the target user and transmits interception events or communication contents obtained by interception to the lawful interception facility according to the interception management information. The invention also provides two methods for transmitting the interception management information and a device for realizing the internet lawful interception. The device comprises an authentication server, a DHCP server and a network access apparatus. The common protocols of the standard DHCP, RADIUS, and the like only need to be simply expanded, and the invention can effectively support the static lawful interception and the dynamic lawful interception and is easy to realize and deploy.

Description

technical field [0001] The present invention relates to the technical field of network communication information security, in particular to a method and device for realizing legal interception on the Internet. Background technique [0002] Legal interception refers to the activities of national security departments to monitor specific telecommunications services within the scope permitted by national laws, such as figure 1 shown. This activity is carried out by the Lawful Interception Authority (LEMF) by issuing an interception order to the network operator / access provider / service provider (NWO / AP / SvP), and its related network equipment provides the communication content and related information of the intercepted object. information to complete. The figure illustrates three typical types of legitimate interception interfaces: management information interface (HI1), interception-related information interface (H12), and communication content interface (HI3) three types of in...
