Example Embodiment

[0077] Example 1:

[0078] Such as figure 1 As shown, there is no nested subnet;

[0079]When there is no nesting of subnets, the entire processing flow is similar to the processing for MN in MIPv6, except that the two need to process authentication options of different formats. NEMO can allow the nesting of subnets. This regulation makes NEMO more robust and also enables it to adapt to the constantly changing network topology in the wireless environment, with strong self-adaptation. RFC3963 stipulates that the processing of data packets in nested NEMO is mainly through tunneling. Although this method can basically handle the scenario of subnet nesting, it also brings many problems, especially in the depth When nesting, problems such as routing redundancy and binding time-consuming are particularly obvious. In such a topology, a relatively large security system like IPSec will bring greater load to these nested MRs. Therefore, in an environment that does not require very high sec...

Example Embodiment

[0088] Embodiment 2: There is a situation of subnet nesting;

[0089] In order to enable the present invention to process NEMO authentication in an optimal manner, the invention proposes a new scheme for processing nested subnets based on the above scheme when there is no nested topology. Based on the new NEMO authentication option we invented above, the only difference is that when there is subnet nesting, the new MR first lets the upper-level MR replace the HA to authenticate the BU sent by the MR, and if it passes, it will continue to forward to the HA. If it fails, refuse to provide services to the MR. Through this optimization, illegal MRs can be found faster, and at the same time, new legitimate MRs can be provided faster, instead of waiting for the MR to register with HA (success or failure) before accepting or rejecting each time. This new MR is especially obvious in the advantages of the deeply nested NEMO topology. The reason why its parent MR can provide such an authent...

Abstract

This invention relates to an effective protection method for home agent signaling information, which protects the signaling information between the mobile router and a home agent by designing a new item selection to bind renewing BU and restoring BA to greatly reduce the process load of the MR and HA to speed up the process of signaling information and switch of the sub-net among different networks, at the same time, to the NEMO structure , the sub-net utilizes a direct linked father MR to certify a new comer sub-MR signaling information, if it is passed, it is transferred, otherwise, it refuses to service for the sub-net.

Description

technical field [0001] The invention relates to a method for effectively protecting home agent signaling messages, which belongs to the field of mobile IP security. Background technique [0002] At present, the research and application of mobile Internet technologies such as mobile IP (RFC3775 mobile IPv6 basic support), mobile network, and mobile / wireless routers have become hot spots. People are no longer satisfied with using a fixed terminal or a single mobile terminal to connect to the network, but hope to organically combine terminals within a certain attribute range to obtain information dynamically on the Internet with a relatively stable set. For example, moving objects such as trains, automobiles, spacecraft, and ships carry a variety of information devices to form a network by means of wired or wireless connections, and dynamically change the connection to the Internet as the location of the moving object changes. [0003] The NEMO working group released the organ...
