Embodiment Construction

[0050] The method of the present invention realizes the safe and reliable IP registration of the mobile node without the mobile IP capability by adopting the method of sending the mobile IP-related mobile security alliance of the mobile node to the mobile IP proxy node when the mobile node is authenticated of.

[0051] The method for secure registration using proxy mobile IP according to the present invention is used for IP registration of a mobile node without mobile IP capability. First, the proxy mobile IP node sends an authentication request message containing at least one random vector to the mobile node, For example, a challenge vector and an authentication vector may be included; then, the mobile node calculates a response vector according to the challenge vector carried in the received authentication request message, and sends an authentication response message containing at least the response vector to the proxy mobile IP node , here, the response vector is calculated...

Abstract

The present invention relates to an agent-based mobile IP communication technology and discloses a method for safety registration by utilizing an agent-based mobile IP. When mobile nodes are authenticated, safe and reliable IP registration of mobile nodes without having mobile IP ability can be achieved by adopting a method that the mobile safety alliance related to mobile IP of mobile nodes are sent to IP agent nodes. Said method in accordance with the present invention is fit for both agent mobile IPv4 and agent mobile IPv6.

Description

technical field [0001] The present invention relates to the communication technology based on proxy mobile IP, in particular, to a method for using proxy mobile IP for safe registration. Background technique [0002] RFC4004 is a protocol for access control and key distribution for mobile nodes (Mobile Node, MN) using the Diameter protocol. This protocol provides a secure registration method, which combines the three Mobility Security Associations (Mobility Security Association) used in Mobile IP, namely, the mobile node and the home agent, the mobile node and the foreign agent, and the foreign agent and the home agent. Mobile Security Alliance, distributed to relevant nodes in the network, so as to realize the secure registration of MIPv4. [0003] The registration method described in this protocol is based on the system framework described in Figure 1, where: [0004] Mobile Node MN: A mobile node is a user terminal equipment that often needs to be handed over between di...
