Abstract

To efficiently provide cloud storage services, most providers implement data deduplication schemes so as to reduce storage and network bandwidth consumption. Due to its broad application, many security issues about data deduplication have been investigated, such as data security, user privacy, etc. Nevertheless, we note that the threat of establishing covert channel over cloud storage has not been fully investigated. In particular, existing studies only demonstrate the potential of a single-bit channel, in which a sender can upload one of the two predefined files for a receiver to infer the information of »0» and »1». In this paper, we design a more powerful deduplicationbased covert channel that can be used to transmit a complete message. Specifically, the key features of our design include: (1) a synchronization scheme that can establish a covert channel between a sender and a receiver, and (2) a novel coding scheme that allows each file to represent multiple bits in the message. To evaluate the proposed design, we implement the covert channel and conduct extensive experiments in different cloud storage systems. Our work highlights a more severe security threat in cloud storage services.
