Problems solved by technology

[0027] 1. The security mechanism of the existing technology does not generate the shared key completely according to the existing AAA architecture. This asymmetric key generation mechanism is quite different from the existing mechanism, which is not conducive to implementation; at the same time, generating the shared key The calculation of the key is relatively large, which will consume a large amount of computing resources of MN and AR;
[0028] 2. During the handove

Embodiment Construction

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0052] Such as Figure 4 Shown is a flow chart of a method for safe and fast switching according to an embodiment of the present invention, which specifically includes the following steps:

[0053] Step 401: Before the fast handover, establish a security association between the mobile node and the access router of the target network;

[0054] Step 402: During the fast handover process of the mobile node, use the security association to ensure that the mobile ...

Abstract

The invention relates to a safe and fast switch method and a system, comprising: building a safe union between a moving node and an access router of objective network before fast switch; using the safe union to ensure the moving node safely accessed to NAR in the fast switch process of the moving node. The device comprises: a safe union building unit and a safe guard protection executing unit. According to the invention, through adjusting the required parameters in key generation in the fast switch process (namely first building the safe union between the moving node and NAR), the process of generating the sharing key is optimized in the fast switch, thereby ensuring the safe mechanism in data transmission not to affect the fast switch flow, and causing he switch process in a controlled range of the network.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method and system for safe and fast switching. Background technique [0002] The mobile IP version 6 (MIPv6, Mobile IP version 6) protocol is a mobile solution proposed by the Internet Engineering Task Force (IETF, Internet Engineering Task Force), which can make the mobile node (MN, Mobile Node) maintain Communication is not interrupted, but it also brings problems such as switching delay and security. [0003] During the handover process, there is a period when the MN cannot determine whether to send or receive data packets, and this period is called handover delay. The main reasons for the handover delay are the delay in the link handover and the operation process of the MIPv6 protocol, such as movement detection, new care-of address (CoA, Care-of Address) configuration, binding update, and so on. In real-time applications such as Voice over IP (VoIP), handover delays are...
