摘要
为了保障网络运行安全,维护网络运行环境,提出基于20-sim软件的网络入侵微分方程反演算法。引入微分方程,在20-sim平台内实现网络入侵模型的构建;通过模型奇点计算,明确网络入侵行为的蔓延程度以及网络入侵行为的扩散趋势。为优化网络入侵模型构建的精准度,引入正则化反演算法,通过对模型构造数据的正则化处理、模型约束目标函数分析,实现反演算法中正则化因子的自适应调节;将正则化反演因子代入反演方程中,实现模型参数向量的推导;根据反演参数推导结果,对网络入侵模型实施纠错与优化。实验结果表明,所提方法能够在较短耗时的前提下,实现网络入侵行为的精准分析,对互联网技术的发展具有重大意义。
To ensure network security and maintain the network operating environment,a differential equation inversion algorithm for network intrusion based on 20-sim software was presented.Firstly,differential equations were introduced to construct a model of network intr usion based on the 20-sim platform.Through the calculation for model singularities,the spread degree and diffusi on trend of network intrusion behavior were clarified.In order to optimize the accuracy of network intrusion model cons truction,a regularized inversion algorithm was introduced.Then,the adaptive adjustment of the regularization factor in the inversion algorithm was achieved through the regularization of construction data and the analysis of the con straint objective function.Finally,the reg ularization inversion factor was substituted into the inversion equation to derive the parameter vector of the model.Acco rding to the result of inversion parameter derivation,the error correction and optimization were implemented on the netw ork intrusion model.Experimental results show that the proposed method can accurately analyze network intrusion beh avior with shorter time consumption,which is of great significance for the development of Internet technology.
