Embodiment Construction

[0015] The invention is applicable to the security application protocol when the WAPI framework method (TePA, an access control method based on ternary peer-to-peer authentication) is applied on specific networks including wireless local area networks and wireless metropolitan area networks.

[0016] Wireless multi-hop networks include low-speed wireless personal area networks, high-speed wireless personal area networks, and wireless sensor networks. This key management method is applicable to these networks.

[0017] The ID-based wireless multi-hop network key management method is described in detail as follows: ID-based wireless multi-hop network key management mainly includes key generation, distribution, storage, modification and revocation.

[0018] The specific implementation of the ID-based wireless multi-hop network key management method is as follows:

[0019] 1. Key generation:

[0020] In the ID-based cryptographic system, since the ID-based private key is equal to...

Abstract

The invention discloses an ID-based wireless multi-hop network key management method which is applicable to a safety application protocol when a WAPI frame method (TePA, an access control method based on the ternary peer-to-peer identification) is applied in a concrete network containing a WLAN, a WMAN and a WPAN. The key management method of the invention comprises the steps of key generation, key distribution, key storage, key modification and key revocation. The invention solves the technical problems that the prior pre-share-key based key management method is not suitable for larger networks and the PKI-based key management method is not suitable for wireless multi-hop networks; the public-key system and the ternary structure are adopted, thereby improving the security and the performance of the wireless multi-hop networks.

Description

technical field [0001] The invention relates to a wireless network key management method, in particular to an ID-based wireless multi-hop network key management method. Background technique [0002] With the development of computer network and global mobile communication technology, portable digital processing terminal equipment has become a necessity in people's daily life and office, these terminal equipment include notebook computers, personal digital assistants (PDA), computer peripherals, mobile phones, pagers and home electronics, etc. They all have strong processing power and large storage space, thus forming a personal operating space (POS). However, at present, most of the information exchange between these terminal devices still depends on the connection of cables, which is very inconvenient to use. People increasingly need a wireless technology to connect these terminal devices in the personal operating space to truly realize the communication between terminal de...
