基于信任度检测的船载网安全路由机制

Secure routing mechanism for shipborne networks based on trust detector

针对当前船载网安全路由机制存在数据传输时延长、链路稳定性差、易被恶意行为攻击等缺陷,为了保证船载网的工作稳定性和通信安全性,设计了基于信任度检测的船载网安全路由机制。首先采用信道选择监听机制对船载网节点信息进行采集,然后采集信息建立节点信任度,并根据节点信任度等级分配数据路由任务,最后根据节点信任度列表建立最优的船载网安全路由,进行船载网安全路由优劣测试。结果表明,本文机制的船载网数据传输时延明显减少,提高了数据传输链路的稳定性,有效避开恶意节点的攻击,船载网的数据吞吐量得到大幅度提升,是一种安全、可靠的船载网安全路由机制。

Aiming at the shortcomings of current safe routing mechanism of Shipborne network,such as data transmission time prolongation,poor link stability and vulnerability to malicious acts,in order to ensure the stability and communication security of shipborne network,a shipborne network based on trust detection is designed.Secure routing mechanism.Firstly,channel selection and monitoring mechanism is used to collect the information of the nodes in shipborne network.Then,the information is collected to establish the trust degree of the nodes,and the data routing tasks are assigned according to the trust degree of the nodes.Finally,the optimal ship is established according to the trust degree list of the nodes.Carrier network security routing,and carries on the ship network security routing superiority and inferiority test.The results show that the data transmission delay of shipborne network is significantly reduced,the stability of data transmission link is improved,and the attack of malicious nodes is effectively avoided.The data throughput of shipborne network is greatly improved.It is a safe and reliable routing mechanism for shipborne network.
