Embodiment Construction

[0035] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] HMIPv6 network architecture such as figure 1 As shown, it is divided into three parts: the first part is the trusted third party, that is, the rootPKG server, which is the default root server of the system, responsible for generating system parameters and issuing private keys for the lower-level PKG servers; the second part is multiple PKG servers and composed of multiple A MAP domain; the third part is the AR router and the mobile terminal MN. When the mobile terminal MN moves and accesses a certain foreign region, an initial access authentication process will occur; when the mobile terminal MN moves in a foreign region and changes access points, a handover authentication process will occur.

[0037] A kind of HMIPv6 network two-way access authentication method for multi-layer MAP, such as image 3 shown, including the f...

Abstract

The invention provides a two-way access authentication method for a multi-layer-MAP oriented HMIPv6 network. The two-way access authentication method comprises the following steps that: a root PKG server is used as a trusted third party; a trusted channel is established among the root PKG server, PKG servers and AR routers in various layers; the root PKG server generates common parameters and private keys; the root PKG server issues the private keys to the PKG servers in the various layers according to identity information of the PKG servers in the various layers; the PKG server in each layer distributes the private key to the AR router in this layer according to identity information of the AR router in this layer; when a mobile node MN leaves a home homework and is accessed to the AR router under a certain MAP in the HMIPv6 network for the first time, initial two-way access authentication is carried out; and, when the mobile node MN is in a currently accessed foreign network and the AR router in the current MAP domain is switched into another MAP domain or another AR router, switching authentication is carried out. The invention provides a short signature scheme based on node certificate hierarchical identity; the security is based on the h-CDH problem; the short signature scheme has the advantages that: the lengths of the private keys are reduced along with increasing of hierarchical levels; and the lengths of the private keys are independent of the hierarchical levels.

Description

technical field [0001] The invention belongs to the field of wireless mobile network access security, in particular to a multi-layer MAP-oriented HMIPv6 network bidirectional access authentication method. Background technique [0002] The rapid development of computer networks has greatly changed people's lifestyles. The Internet is developing towards supporting large-scale mobility, and people have higher requirements for networks. With the rapid development of broadband wireless access technology and mobile terminal technology, the number of mobile devices and the demand for access to the network continue to increase, Mobile IPv6 (MIPv6) will become an important supporting protocol for the next generation of mobile communications. In order to further improve the applicability of MIPv6 and the handover efficiency of mobile nodes in foreign networks, IETF has extended MIPv6 and formulated a hierarchical mobile IPv6 protocol (HMIPv6), which introduces mobile anchor points in ...
