摘要
在分析云计算安全现状的基础上,针对云计算服务模式的特征,建立了一种基于随机Petri网模型的用户行为验证模型,引入用户访问资源或调用服务的行为习惯度,主要包括选择概率偏离度和服务占用时间两个度量.此模型利用用户访问习惯度进行身份验证,以此来访问用户资源并调用服务行为,是一种有效的云计算用户行为验证技术,且实例分析表明其具有很好的实用性.
Security status quo was described firstly on the basis of analysis of cloud computing for the characteristics of the cloud computing service model.The user behavior model was established based on the stochastic Petri nets by introducing the behavior of users to access resources or call the service, including the degree of two metrics that deviation of the probability of selection and service occupancy time of accessing to resources and calling the service.The authenticate users access habits degree is used in this model,which is proved to be a new and effective cloud computing user behavior authentication technology,and has a good practicality.
