摘要：

基于分布式云存储系统利用椭圆曲线和散列函数等内容，提出了一种云环境下的双向身份认证方案，实现双向认证过程。新方案的优点在于产生对通信双方公正的会话密钥，同时设计了2种不同类型的认证： 本地网内认证和跨网络认证。最后对该方案进行了安全性和性能分析，证明了本方案具有很强的安全性，能够保护用户的隐私性和抗抵赖性，且具有较低的计算量。该方案满足云存储在通信环境中的需求。

Abstract:

Under the mutual identity authentication, a scheme based on distributed cloud storage system was proposed, using symmetric encryption algorithm and hash function to realize bidirectional authentication process. Advantages of the novel project are to produce fair session key to both communications, and design the two different types of authentication:within the network and across a network authentication. Then the security of this scheme was analyzed. The scheme is more secure than the former ones and it can protect the privacy of users and non-repudiation, and has lower computa-tional cost. Therefore, this scheme can meet the demand of cloud storage communication environments.

Key words: distributed file system, identify authentication, cloud storage, date interaction
