网络混合型信息传输安全性预测仿真

Security Prediction Simulation of Network Mixed Information Transmission

对网络混合型信息传输安全性进行预测,可提高数据传输效率,保障网络整体安全性和正常运行。对混合型信息的传输安全性进行预测,需要通过主机信息传输的威胁指数,生成主机信息传输的基础威胁维,完成对混合型信息传输安全性的预测。传统方法根据原始序列的累加,对不规则的扰动进行弱化,但忽略了对主机信息传输基础下的威胁维进行求取,导致预测精度偏低。提出基于时间序列的网络混合型信息传输安全性预测方法。构建有向信息传输安全态势的复杂网络,根据主机基础信息传输维指数,生成主机基础信息传输维,通过主机信息传输的威胁指数,生成主机信息传输的基础威胁维;以主机信息传输的安全态势为依据,实现整个网络网络混合型信息传输安全态势预测。实验证明,所提方法收敛性优于当前方法,信息传输安全性预测值与实际值具有较强的拟合程度。

To predict the security of network mixed information transmission can improve the data transmission ef- ficiency and ensure the security and normal operation of network. Traditional methods ignore the calculation of threat dimension based on the host information transmission. Therefore, a method for predicting the security of network mixed information transmission based on time series is proposed. Firstly, a complex network of security situation of oriented information transmission is established. According to the dimension index of host basic information transmission, the host basic information transmission dimension is generated. Through threat index of host information transmission, the basic threat dimension of host information transmission is generated. Moreover, on the basis of security situation of host information transmission, the security situation of network mixed information transmission is predicted. Simulation shows that the proposed method has better convergence than current methods. The predicted value of the information transmission security has a strong fitting degree with the actual value.
