摘要
云计算的发展带来了科技领域的深刻变革,因其便利性、经济性、可扩展性等优势获得了越来越多政企的青睐,与此同时云上应用的安全性也成为各方关注的焦点。密钥安全是密码安全的基础,在云计算环境中,不仅云上的各类应用需要更方便、安全的密钥管理服务,云系统本身也面临着用户数量多、数据量大等问题,亟待划分粒度更细、使用更加灵活的密钥管理方式。在云环境密钥管理的背景下,提出了一种基于用户行为分析的异常检测方法,按各用户的历史行为分析其当前操作的合法性。所提方法具有动态灵活、智能性强的特点,对拒绝服务攻击也具有一定的防护作用。
The development of cloud computing brings profound changes to the field of science and technology.With its convenience,affordability,scalability and other advantages,more and more governments and enterprises are favorable to it,while at the same time,the security of cloud applications becomes the focus of attention.Key security is the foundation of cryptographic security.In the cloud computing environment,not only all kinds of applications on the cloud need more convenient and secure key management services,but also the cloud system itself is facing many problems such as large number of users and large amount of data,so there is an urgent need for a key management method with finer granularity of division and more flexible usage.In the context of cloud environment key management,an exception detection method based on user behavior analysis is proposed,which analyzes the legitimacy of each user’s current operation according to its historical behavior.The proposed method is dynamic,flexible and intelligent,and also has a certain protective effect against denial-of-service attacks.
