随着大数据时代的到来和网络存储技术的蓬勃发展,云计算环境依赖云存储系统为用户提供数据快速存储与检索等服务.越来越多的企业和个人将数据存储至云空间,数据完整性与数据访问控制成为用户最关心的问题.为了保障用户数据安全,针对近年来各大云服务提供商不断暴出安全事故问题,利用演化博弈理论和方法构建云存储服务方的演化博弈模型,并对策略选择进行稳定性分析.博弈分析结果表明:提高用户对云存储服务信誉度的重视程度,推动云存储技术发展及加强政府对信息安全问题的监管力度是保障云存储数据安全的有效途径.
With the advent of the era of big data and the flourishing development of network storage technologies, the cloud computing environment relies on cloud storage systems to provide users with services such as fast data storage and retrieval, etc. More and more enterprises and individuals store data in cloud space and complete data In order to ensure the security of user data, aiming at the problem that the major cloud service providers keep breaking out of safety accidents in recent years, this paper constructs the evolutionary game model of cloud storage service side by using evolutionary game theory and method, And analyzes the stability of strategy selection.The game analysis shows that improving the user’s emphasis on cloud storage service credibility, promoting the development of cloud storage technology and strengthening the government’s supervision of information security are effective ways to ensure cloud storage data security .
