Embodiment Construction

[0033] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0034] The invention provides a wireless Mesh network routing security protection method, such as Figure 11 As shown, the method includes the following steps:

[0035] The request authentication code field is set in the routing request frame, the request authentication code field is encrypted in the manner of broadcast key encryption and one-hop key encryption, and the routing request frame is transmitted into the wireless Mesh network; The routing request frame is transmitted through two-hop authentication until the routing request frame reaches the destination node or reaches a qualified relay node;

[0036] After the destination node receives the routing request frame, ...

Abstract

The invention relates to the technical field of wireless Mesh network routing protocols and security specifications, in particular to a wireless Mesh network routing security protection method based on the 802.11s standard routing protocol. The present invention forms a set of new security mechanisms by adding extended fields on the basis of the original frame structure, which is fully compatible with the original security mechanisms of 802.11s, and meanwhile provides extended routing frame routing security protection for wireless Mesh network characteristics, It makes up for the shortcomings of the 802.11s standard in terms of routing security, can meet strong security requirements, and effectively resist path transfer attacks, masquerading attacks, flooding attacks, passive attacks, and replay attacks, etc. Deployment in the Mesh network system does not require additional facilities or equipment; the wireless Mesh network routing security protection method provided by the present invention is applicable to wireless transmission communication networks such as vehicle-mounted networks, large-scale video surveillance networks, sensor networks, and backbone networks, and Provide routing security protection for the above-mentioned related networks.

Description

technical field [0001] The invention relates to the technical field of wireless Mesh network routing protocols and security specifications, in particular to a wireless Mesh network routing security protection method based on the 802.11s standard routing protocol. Background technique [0002] For the complex terrain and harsh environment, how to safely and efficiently meet the large-scale Internet network coverage, the high-bandwidth transmission of a large amount of production data in the LAN, and the positioning of mobile devices and network access are related to the quality of communication and the normal development of related application services. important question. Although the traditional wired network has high transmission bandwidth, it has high deployment and maintenance costs and limited coverage in complex and harsh environments. The current wireless network access method is mainly based on bridge technology, which has limitations on network scale, number of nod...
