Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] The present invention is aimed at the AODV agreement control message that is used for routing in the wireless Mesh network based on Ad-hoc highly security sensitive, has introduced message checking and encrypting, thereby guarantees that route request message (RREQ), route response message ( RREP) and routing error message (RERR) are not easy to be camouflaged, cracked, or tampered and not easily authenticated, thus ensuring the security of the entire wireless Mesh network.

[0033] Such as figure 1 As shown, it is a schematic diagram of an embodiment of the Ad-hoc-based wireless Mesh netwo...

Abstract

The present invention provides a wireless Mesh network security system based on Ad-hoc. According to a wireless Mesh network based on the Ad-hoc, the routing of network nodes is achieved through an Ad hoc On-Demand Distance Vector Routing (AODV) protocol, the network nodes comprise a check code creating unit, an encryption unit and a message sending unit, wherein the check code creating unit is used for generating check codes according to message type fields of a control message and content fields and adding the check codes to expansion fields at the end of the control message; the encryption unit is used for encrypting an encryption sector of the control message, and the encryption sector does not comprise the message type fields of the control message; and the message sending unit is used for sending an encrypted control message. The invention further provides a corresponding wireless Mesh network security method based on the Ad-hoc. The message is controlled through the AODV protocol to check, encrypt and transmit the check mode, and the security of a whole wireless Mesh network can be guaranteed.

Description

technical field [0001] The present invention relates to the field of network security, more specifically, to an Ad-hoc-based wireless Mesh network security system and method. Background technique [0002] Ad-hoc network is a special wireless mobile network, in this network, all nodes have equal status, without setting up any central control node. Moreover, the nodes in the network not only have the functions required by ordinary mobile terminals, but also have message forwarding capabilities. Because the wireless Ad Hoc network has outstanding advantages such as fast networking, flexible structure, high transmission rate, strong reliability, and low cost, it is suitable for digital, intelligent, and miniaturized embedded systems, and is gradually used in industrial control and military applications. field. [0003] AODV (Ad hoc on-demand distance vector routing) is a source-driven routing protocol. When a node needs to transmit information to other nodes in the network, i...
