摘　　要：云计算为用户提供了资源动态分配解决策略,能够按用户需求处理海量数据,其对于互联网海量数据存储与处理具有良好的应用。但是云计算环境下的数据安全问题是其可持续发展与健康应用的关键。本文对目前云计算环境中的数据安全因素进行分析,探究云计算环境下的数据完整性保护、数据共享时的安全保护和数据存储载体的安全保护。提出基于MB-tree数据结构方式提高数据完整性的保护。在数据共享时的安全保护方面通过扩展的模糊身份加密机制保证数据交互的隐私保护。在数据存储载体的安全保护方面提出构建虚拟机可信平台VTPM模块,保证虚拟机在信任环境中迁移。Cloud computing provides users with a dynamic resource allocation solution,which can deal with massive data according to user needs.It has good application for massive internet data storage and processing.However,the data security problem in cloud computing is the key to its sustainable development and application.This paper analyzes the data security factors in the cloud computing environment,and explores the data integrity protection,data sharing security protection and data storage carrier security protection in the cloud computing environment.MB-tree data structure is proposed to improve data integrity protection.The extended fuzzy identity encryption mechanism ensures the privacy protection of data interaction in the aspect of data sharing security protection.In the aspect of security protection of data storage carrier,a virtual machine trusted platform VTPM module is proposed to guarantee the migration of virtual machine in trust environment.
