Problems solved by technology

Such a multicast tree cannot meet the needs of applications when there is a shortage of resources and quality of service requirements
These proposed QoS multicast routing protocols for mobile ad hoc networks have no security-related settings, and all nodes involved in communication are implicitly trusted, and malicious nodes will forge, tamper or even disrupt the exchange of data packets or bypass normal routing. behavior that seriously threatens this relationship of trust

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] 1) network model and QoS multicast routing problem involved in the present invention are defined as follows:

[0022] Definition 1 A network can be expressed as a weighted graph G=(V, E), where V represents the node set, and E represents the communication link set connecting the nodes. |V| and |E| represent the number of nodes and links in the network, respectively. For the sake of generality, we only consider such a type of graph, that is, in this type of network, there is at most one link between a pair of nodes, and the parameters beside the link can be used to describe the current state of the link.

[0023] Definition 2 Let p(s, t) represent the path from source node s to end node t, and T(s, M) represent the multicast tree. s∈V is the source node of a multicast tree, and M{V-{s}} is the end node or leaf node set of the multicast tree.

Abstract

The related HORSEI2 based building method for self-organizing network security QoS multicast route comprises: every transmitter and receiver can add the multicast security group only being checked by visits control mechanism to obtain the private and public key of HORSEI2; every node requiring for creating / receiving new security multicast dialogue data creates / adds safe QoS multicast tree, wherein the transmitter applies signature on the message generated by HORSEI2, and the receiver uses the public key for verification.

Description

technical field [0001] The invention belongs to the technical field of network security, and relates to a method for establishing a HORSEI2-based secure QoS multicast route of a mobile ad hoc network. Background technique [0002] Mobile communication networks can be divided into two categories: with base station support and without base station support. The former includes existing GSM, CDMA, CDPD and other networks; the latter is the mobile ad hoc network. Mobile ad hoc network is a multi-hop temporary autonomous system composed of a group of mobile nodes with wireless transceiver devices. In this environment, due to the limited wireless communication coverage of nodes, it is necessary to use intermediate nodes for packet forwarding Arrive at Xinsu. It can provide a usable communication support environment where no network infrastructure is available. [0003] The mobile ad hoc network is a wireless mobile network without central infrastructure sup...
