Abstract
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.
