Anti-proof attack method of optical fiber communication link

针对现有防御保护方法在高校校园光纤通信链路中应用存在防御节点设置误差大,无法有效保护受篡改攻击通信链路传输安全性的问题,开展高校校园光纤通信链路防篡改攻击方法设计研究。建立高校校园光纤通信链路篡改攻击检测模型,对通信传输链路的篡改攻击检测;设立防御通信节点的位置,对防御通信节点身份信息认证,确定篡改攻击防御通信节点;利用防御通信网络节点,实现对光纤通信链路篡改攻击的保护。通过实例证明,新的方法可以有效降低防御通信节点设置误差,促进光纤通信链路安全性提升。

In view of the application of existing defense protection methods in university campus optical fiber communication links,which has large error in defense node setting and cannot effectively protect the transmission security of tampered attack communication links,the design of tamper-proof attack method of university campus optical fiber communication links is carried out.Establish the tampering attack detection model of optical fiber communication link of university campus to detect the tampering attack of communication transmission link,set up the position of defense communication node,authenticate the identity information of defense communication node,determine the tamper attack defense communication node,and use the defense communication network node to protect the tampering attack of optical fiber communication link.The example proves that the new method can effectively reduce the setting error of the defense communication node and promote the security of the optical fiber communication link.
