云存储是当前信息技术领域的研究热点。在云存储中，数据的机密性、完整性和可用性等数据安全属性在许多商业应用中变得越来越重要。近年来，许多可证明数据占有(PDP)方案被提出来保护数据的完整性。在某些情况下，它必须将远程数据拥有检查任务委托给某个代理。然而，这些PDP方案是不安全的，因为代理将一些状态信息存储在云存储服务器中。因此，本文提出了一种高效的可相互验证的可证明数据拥有方案，该方案利用Diffie-Hellman共享密钥构造同态认证器。特别是，我们方案中的验证器是无状态的，独立于云存储服务。值得注意的是，与以前的PDP方案相比，该方案是非常有效的，因为不需要双线性运算。
Cloud storage is now a hot research topic in information technology. In cloud storage, date security properties such as data confidentiality, integrity and availability become more and more important in many commercial applications. Recently, many provable data possession (PDP) schemes are proposed to protect data integrity. In some cases, it has to delegate the remote data possession checking task to some proxy. However, these PDP schemes are not secure since the proxy stores some state information in cloud storage servers. Hence, in this paper, we propose an efficient mutual verifiable provable data possession scheme, which utilizes Diffie-Hellman shared key to construct the homomorphic authenticator. In particular, the verifier in our scheme is stateless and independent of the cloud storage service. It is worth noting that the presented scheme is very efficient compared with the previous PDP schemes, since the bilinear operation is not required.
