基于区块链技术的机会网络安全性研究

Research on opportunity network security based on block-chain technology

机会网络由于具有间歇式连接、多跳转发等特点,很容易遭受恶意攻击。文章提出一种基于区块链技术的节点身份识别方案,可以检测出破坏网络的恶意节点,在此基础上改进了Epidemic路由,在提高消息投递率的同时,降低了网络开销和平均延迟。通过仿真实验,证实了该方案可以有效地防范各种恶意攻击,在消息投递率、平均延迟、网络开销以及恶意节点检测率等方面均优于传统方案。

Opportunity network is vulnerable to malicious attack because of its intermittent connection,multi-hop forwarding and so on.In this paper,a node identification scheme based on block chain technology is proposed,which can detect malicious nodes in broken ring networks.On this basis,the Epidemic routing is improved,which not only improves the message delivery rate,but also reduces the network overhead and average delay.The simulation results show that the scheme can effectively prevent all kinds of malicious attacks,and it is superior to the traditional scheme in message delivery rate,average delay,network overhead and malicious node detection rate.
