当数据存储在公共云中时，可证明的数据拥有（简称PDP）在云存储中至关重要。PDP可以使用户验证他们的外包数据是否保持完整，而无需下载整个数据。在某些应用场景中，为了保护用户身份隐私，匿名性非常重要。为了鼓励用户披露不良事件，政府或组织或个人可能会为提供宝贵数据的用户支付费用。因此，激励和无条件匿名的基于身份的公共PDP（简称IAID-PDP）是一个非常重要的安全概念。从上述需求出发，我们首次提出了IAID-PDP的概念。我们形式化了它的系统模型和安全模型。基于双线性对，给出了一个具体的IAID-PDP协议。基于标准困难问题，所提出的IAID-PDP协议是可证明安全的。IAID-PDP协议采用基于身份的公钥密码体制，避免了复杂的证书管理。通过性能分析和安全性分析，我们的IAID-PDP协议满足以下性质：证书消除，激励，无条件匿名和远程数据完整性检查。
When the data is stored in public clouds, provable data possession (for short, PDP) is of crucial importance in cloud storage. PDP can make the users verify whether their outsourced data is kept intact without downloading the whole data. In some application scenarios, anonymity is very important in order to protect the user identity privacy. In order to encourage users to disclose bad event, the government or organization or individual may pay for the user who provides the precious data. Thus, incentive and unconditionally anonymous identity-based public PDP (for short, IAID-PDP) is a very important security concept. From the above requirements, for the first time, we propose the concept of IAID-PDP. We formalize its system model and security model. Based on the bilinear pairings, a concrete IAID-PDP protocol is presented. Based on the standard hard problems, the proposed IAID-PDP protocol is provably secure. IAID-PDP protocol eliminates the complex certificate management since it is designed in the identity-based public key cryptography. Through the performance analysis and security analysis, our IAID-PDP protocol satisfies the following properties: certification elimination, incentive, unconditional anonymity and remote data integrity checking.
