摘 要 现今社会，信息化发展的越来越快，网络成为了越来越多人工作和生活不可或缺的一部分。然而，网络上的系统和手机上的应用在便捷人们生活的同时，也带来了越来越多的信息安全问题。文章介绍了通过运用 BP 神经网络，预测网络病毒的传播特性和规律。此前 BP 神经网络算法对于各方面的研究非常广泛，并且建立起符合实际的情况的预测模型，模拟效果很好。同时 BP 神经网络模拟病毒的传播过程，预测效果具有现实意义。可是很多工程学者都将生物病毒和计算机病毒分开进行研究，他们认为这两种病毒间具有比较大的不同，而数学家们却不这么认为，他们将网络病毒与生物病毒使用相同的方法进行一同研究。针对计算机网络的特点，借鉴目前生物病毒已实现的 BP 神经网络的预测模型探索计算机网络病毒的变化趋势，绘制预测模型，为制定策略进一步防控网络病毒提供依据。 该论文有图16幅，表 3个，参考文献38篇。 50853

Research on network virus prediction based on Neural Network
Abstract Nowadays, becoming an information based society development faster and faster, the network has become a more and more people work and an essential part of life. However, on the network system and a mobile phone application in convenient people's life at the same time, also brought more and more of the information security problem. The article by using the BP neural network is introduced, prediction of network virus propagation characteristics and laws. The BP neural network algorithm for all aspects of the study is very broad, and established in accordance with the actual situation of forecasting model, simulation effect is very good. Process of BP neural network to simulate the spread of the virus at the same time, the forecast effect has a realistic significance. But many engineering scholars have separate biological viruses and computer virus, they think it has the bigger of the two different between two kinds of virus, and mathematicians don't think so, they will network viruses and biological viruses use the same method to study together. According to the characteristics of the computer network, referring the biological virus has implemented the BP neural network prediction model to explore the changing trend of the computer network virus, draw the prediction model, provide the basis for further prevention and control strategy network virus.
Key Words: BP neural network; network virus transmission; network virus prediction model; principal component analysis;
