受攻击后的网络可靠性估计模型设计

Design of reliability estimation model of network after attack

网络受到攻击入侵后容易出现信道失稳和链路输出失真,导致网络的可靠性下降,因此提出一种基于自适应均衡的受攻击后的网络可靠性估计模型。构建网络受攻击后的传输链路模型,采用链路衰落调制方法减少网络攻击对传输信道的损害,对网络传输信道进行分段均衡处理,采用自适应加权算法进行链路失真补偿,实现网络链路自适应均衡。仿真试验结果表明,采用该方法进行受攻击后的网络可靠性估计提高了对网络入侵的检测能力,抑制了攻击对网络的信道损害,提高网络安全性。

It is easy to occur channel instability,link output distortion,and network reliability reduction after network attack and intrusion.Therefore,an adaptive equalization based reliability estimation model of network after attack is proposed.The transmission link model after network attack is constructed.The link fading modulation method is adopted to reduce transmission channel damage from network intrusion.The segment equalization is performed for network transmission channels.The adaptive weighted algorithm is used to compensate link distortion and realize network link adaptive equalization.The simulation results show that the method for the reliability estimation of network after attack can enhance the capability of detecting network intrusion,suppress channel damage from network attack,and improve network security.
