摘要/Abstract

摘要： 针对复杂的网络安全态势预测问题,为了提高预测的收敛速度和预测精度,提出了一种基于改进粒子群优化双向长短期记忆(IPSO-BiLSTM)网络的网络安全态势预测模型。首先,针对所用数据集没有真实态势值的问题,采用了一种基于攻击影响的态势值计算方法,用于态势预测。其次,针对粒子群(PSO)算法易陷入局部最优值、搜索能力不均衡等问题,对惯性权重和加速因子进行改进,改进后的粒子群(IPSO)算法的全局和局部搜索能力平衡,收敛速度更快。最后,使用IPSO优化双向长短期记忆(BiLSTM)网络参数,提升预测能力。实验结果表明,IPSO-BiLSTM的拟合程度可达0.994 6,其拟合效果和收敛速度均优于其他模型。

Abstract: Aiming at the complex network security situation prediction problem,a network security situation prediction model based on improved particle swarm optimization bidirectional long-short term memory(IPSO-BILSTM) network is proposed to improve the convergence speed and prediction accuracy.Firstly,in view of the lack of real situation value in the data set,a situation value calculation method based on attack influence is adopted for situation prediction.Secondly,to address the problems that particle swarm optimization(PSO) algorithm is prone to fall into local optima and unbalanced search capability,the inertia weights and acceleration factors are improved,and the improved particle swarm optimization(IPSO) algorithm has balanced global and local search capability and faster convergence speed.Finally,IPSO is used to optimize the parameters of bidirectional long short term memory(BiLSTM) network,so as to improve the prediction ability.Experimental results show that the fitting degree of IPSO-BiLSTM can reach 0.994 6,and the fitting effect and convergence speed are better than other models.

Key words: Bidirectional long-short term memory, Improved particle swarm optimization, Network security, Neural network, Situation prediction
