A satellite self-organizing network olsr security routing system based on blockchain technology

Abstract

The invention discloses a satellite self-organizing network OLSR security routing system based on block chain technology, including a network facility layer, a consensus layer, a function layer and an application layer. The network facility layer includes satellite nodes that make up the self-organizing network of small satellites; the consensus layer completes bookkeeping through the consensus mechanism; The records are distributed and stored among the nodes; the application layer is based on the trusted records of the underlying network, and provides functions such as message spoofing attack identification and reputation reference for satellite nodes. In the present invention, when a malicious node initiates a message spoofing attack, other satellite nodes can identify the HELLO message and TC message containing false content, so as to realize the defense against the message spoofing attack. At the same time, through the reputation reference function provided by the security framework, malicious nodes Punish it so that it cannot continue to destroy the network and ensure the traffic security of the network.

Description

technical field [0001] The invention relates to the technical field of micro-nano satellite constellation network, in particular to a satellite self-organizing network OLSR security routing system based on block chain technology. Background technique [0002] In recent years, with the rapid development of wireless communication and mobile communication, new mobile communication technologies emerge in an endless stream to enable people to exchange various information with other people in any way at any time and any place. Among them, the rapid development of satellite network makes satellite communication one of the most important communication methods in mobile communication technology. With the increasing demand of users for communication, the traditional network link on the ground to achieve inter-regional communication is far from enough. When encountering various complex terrains such as mountains, oceans and islands, It is difficult for the communication network on the...

Problems solved by technology

[0014] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a satellite self-organizing network OLSR security routing system based on block chain technology to solve the problem that when a malicious node initiates a message spoofing attack, other satellite nodes can pass the block chain-based The security framework identifies the HELLO message and TC message containing false content to realize the defense against message spoofing attacks. At the same time, through the reputation reference function provided by the security framework, malicious nodes are punished so that they cannot continue to damage the network and protect the network traffic security
