随着云存储的普及和扩散，数据安全正在成为云存储用户最关心的问题之一。数据完整性作为云安全的重要内容之一，一直是云安全领域的研究热点。目前已经提出了许多数据完整性审计方案，但是这些方案都是基于第三方审计者（TPA）是安全可信的假设。如果TPA变得邪恶，这些方案很容易使云服务器遭受分布式拒绝服务（DDOS）攻击。针对这一问题，本文提出了一种审计次数受限的授权审计方案。在我们的方案中，只有授权的TPA可以向云进行有效的挑战，以进行数据完整性检查。此外，授权TPA可以进行的总审计次数由用户决定。在我们的构造中，一个受约束的审计号码集成到用户生成的授权，以实现这一属性。一旦TPA的审计次数达到限制，云服务器将不会响应此TPA的挑战，这从字面上排除了DDOS攻击的威胁。分析和实验结果表明，该方案是安全和有效的。
As the popularity and the proliferation of cloud storage increase, data security is becoming one of the biggest concerns for users of cloud storage. How to preserve the data integrity, as one of the most important security aspects, has been a research hotspot in the field of cloud security. Many data auditing schemes for checking the data integrity have been presented, however, these schemes are based on the assumption that the third party auditor (TPA) is secure and trustworthy. If TPA becomes wicked, these schemes are easy to make cloud server suffer distributed denial-of-service (DDOS) attack. In order to deal with this problem, we propose an authorized auditing scheme with constrained auditing number in this paper. In our scheme, only authorized TPA can make valid challenges to cloud for data integrity checking. Moreover, the total auditing number that an authorized TPA can make is decided by the user. In our construction, a constrained auditing number is integrated into the authorization generated by user to achieve this property. Once the number of a TPA’s auditing reaches the constraint, cloud server will not respond to this TPA’s challenges, which literally rules out the threat of DDOS attack. Analysis and experimental results show the proposed scheme is secure and efficient.
