摘要

Wang 等人提出了 "在线/离线可证明数据占有"（OOPDP）的概念[IEEE Transactions on Information Forensics and Security, 12(5)：1182-1194, 2017]，并提出了两种实例，即：基于 CDH 的 OOPDP 和优化的 OOPDP：基于 CDH 的 OOPDP 和优化的 OOPDP。然而，本文揭示了基于 CDH 的 OOPDP 和优化的 OOPDP 中的标记都可以被修改，而且优化的 OOPDP 容易受到已知的单文件标记攻击。然后，我们展示了如何通过两种改进方案来解决这些（之前未披露的）漏洞，我们还展示了改进方案在不增加用户端计算开销的情况下，仅占用云上标签存储空间的 61.5%。

Revisiting “online/offline provable data possession” schemes

Wang et al. proposed the concept of “online/offline provable data possession” (OOPDP) [IEEE Transactions on Information Forensics and Security, 12(5): 1182-1194, 2017], and presented two instantiations, namely: CDH-based OOPDP and optimized OOPDP. However, in this paper we reveal that the tags in both CDH-based OOPDP and optimized OOPDP can be modified, and the optimized OOPDP is vulnerable to known one-file-tag attack. Then, we demonstrate how the (previously unrevealed) vulnerabilities can be addressed in two improved schemes, which we also show that the improved schemes incur only 61.5% of the storage space for tags on the cloud without increasing computational overhead at the user-end.

期刊介绍： The quality of software, well-defined interfaces (hardware and software), the process of digitalisation, and accepted standards in these fields are essential for building and exploiting complex computing, communication, multimedia and measuring systems. Standards can simplify the design and construction of individual hardware and software components and help to ensure satisfactory interworking. Computer Standards & Interfaces is an international journal dealing specifically with these topics. The journal • Provides information about activities and progress on the definition of computer standards, software quality, interfaces and methods, at national, European and international levels • Publishes critical comments on standards and standards activities • Disseminates user''s experiences and case studies in the application and exploitation of established or emerging standards, interfaces and methods • Offers a forum for discussion on actual projects, standards, interfaces and methods by recognised experts • Stimulates relevant research by providing a specialised refereed medium.
