摘　　要：针对传统光纤网络防御方法中防御能力较低且不能有效缓解和防御恶意攻击的问题,提出一种光纤通信网络中的链路数据篡改攻击与防御方法。建立链路层中所有数据种类的检测样本集,根据破解繁琐度信号的规划原则,获取有关篡改攻击的函数转换信号,计算每个数据集间信号的关联程度,寻找与篡改攻击信号最为接近的数据,确定链路层是否遭受侵害。根据数据间双重传输规则,计算每个传输节点间欧式距离,根据距离阈值确定相应防御节点。将所有篡改攻击数据的二进制代码进行语言转换协议,并实施封包处理,使用密钥对链路数据层进行加密,完成光纤通信网络中链路数据篡改攻击与防御。实验结果表明,所提方法对光纤通信网络中链路数据篡改攻击与防御精度较高,且攻击防御节点设置误差较低。Aiming at the problem that the traditional defense methods of optical fiber network have low defense capability and can not effectively mitigate and defend against malicious attacks,this paper proposes a link data tampering attack and defense method in optical fiber communication network.The detection sample set of all kinds of data in the link layer is established.According to the planning principle of cracking the cumbersome signal,the function conversion signal about tampering attack is obtained.The correlation degree of signals between each data set is calculated,and the data closest to the tampering attack signal is found to determine whether the link layer is violated.According to the dual transmission rules between data,the Euclidean distance between each transmission node is calculated,and the corresponding defense node is determined according to the distance threshold.All the binary code of tampering attack data is converted into language protocol,and the packet is processed.The key is used to encrypt the link data layer to complete the link data tampering attack and defense in optical fiber communication network.The experimental results show that the proposed method has high precision for link data tampering attack and defense in optical fiber communication network,and the attack defense node setting error is low.
