Problems solved by technology

Therefore, the data packets will be processed through the tunnels of HA, FA (for the mobile IPv4 system), wireless equipment and MN respectively, and many of the data packets are illegal data packets, thereby reducing the security of the mobile IP network and causing Resource waste of HA, FA, MN and wireless channel
[0009] On the other hand, if the MN is accidentally infected with a virus or the MN deliberately attacks the network and spreads the virus, if it is not controlled, it will also cause great harm to the network

Embodiment Construction

[0047] The present invention provides a solution method and system for a mobile IP network security solution. The core of the present invention is: actively configure or automatically issue user security policies at the HA, and send illegal data to or from the MN Packets are filtered and shielded.

[0048] Describe the present invention in detail below in conjunction with accompanying drawing, the schematic diagram of the method of the present invention is as image 3 As shown, the specific processing flow of this method is as follows Figure 4 shown, including the following steps:

[0049] Step 4-1. Actively configure or automatically deliver the user's security policy at the HA.

[0050] The present invention first needs to actively configure or automatically deliver user security policies at the HA.

[0051] The process for users to actively configure their own security policies is as follows:

[0052] Users may need, for example, after receiving a large number of abnor...

Abstract

The present invention provides a solution method and system for a security scheme of a mobile IP network, the method mainly includes: configuring a security policy of the mobile node on the home agent of the mobile node in the mobile IP network; according to the security policy, The home agent performs security control processing on the received data packets destined for or sent by the mobile node. It can reduce the chance of mobile nodes being attacked, reduce the spread of viruses and spam, ensure the safe operation of mobile IP networks, and avoid unnecessary waste of mobile IP network resources.

Description

technical field [0001] The present invention relates to the communication field, in particular to a solution method and system for a mobile IP network security solution. Background technique [0002] Mobile IP is a solution to provide users with mobile functions on the Internet. Mobile IP can go beyond the limitation of geographical scope and has the characteristics of scalability, reliability and security. Mobile IP expands the mobile and roaming capabilities of users, and can enable nodes to maintain ongoing communication during handover. [0003] In Mobile IP, MN (Mobile Node) can be connected to any link with a permanent IP address. While mobile IP provides a wide range of mobility for terminals, it can also ensure the assignability and reachability of IP addresses for terminals. The mobile IP system mainly includes MN, FA (foreign agent), HA (home agent) and CN (communication node), for the mobile IPv6 system, FA foreign agent is not included). [0004] In Mobile IP...
