模拟复杂网络下子网络节点抗攻击设计

针对复杂网络节点受攻击而出现的安全性问题,提出在模拟复杂网络基础上结合Feistel算法的子网络节点抵抗攻击方法。该方法通过子网络节点定位参数集,建立恶意节点位置模型,并确定定位真实精度；而后利用Feistel算法对节点密文进行加密处理,进而使加密信息恢复成明文信息,完成模拟复杂网络下子网络节点的抗攻击方法改进。结果证明,该方法不仅能够准确的对恶意节点进行定位,而且增强了节点抗攻击性能,提升了网络安全性。

Simulate the Design of Anti - attack on Network Nodes of Complex Network

Aiming at the security problem of complex network nodes attacked, a method of resisting attack is proposed for subnet nodes based on Feistel algorithm in the simulation of complex networks. By means of the method of sub network node location parameter set, a malicious node location model, and determine the true positioning accuracy; then using Feistel algorithm of node ciphertext encrypted, and the encrypted information back into plaintext information, improve the anti attack method to simulate network nodes of complex networks to complete immediately. The results show that this method can not only locate the malicious nodes accurately, but also enhance the anti attack performance of nodes and improve the security of the network.
