摘　　要：云存储是在云计算概念上延伸和发展出来的一个新的概念，旨在对外提供数据存储和业务访问服务。在分析云存储基本概念、结构和特点的基础上，对云存储的安全性进行了研究和分析。云存储的安全性问题是制约云存储发展的首要问题．针对非法访问、数据泄漏、数据存取故障等安全问题提出了挑战一应答式的云存储身份认证、基于用户与密钥关联的加密存储、数据恢复等多项安全解决方案，能够避免传统身份认证口令被攻击的风险，使用户可以选择加密算法使用密钥进行数据加密，以及透明地为用户提供快速且与存取并行的数据恢复。Cloud storage is a new extension and developed concept on the base of the cloud computing, ainling at providing data storage and transaction access server. On the base of the analysis of the basic concept, structure and characteristics of cloud storage, make research and analysis on safety of cloud storage. Safety problems of cloud storage has been the primary problem that restricted the development of cloud storage. For the unauthorized access, data leakage, data access breakdown and other security problems, poses some security solutions, including a challenge-response cloud storage identity authentication, based on the user and key associated encryption storage, data recovery, which can avoid the risk of password being attacked in the traditional identity authentications, also make the user can choose enciyption algorithm and use the key to encrypt the data, and provide a fast and parallel with data access data recovery server which is transparent to users.
