ABSTRACT:
With the advent of cloud computing,
more and more people tend to outsource their data to the cloud. As a
fundamental data utilization, secure keyword search over encrypted cloud data
has attracted the interest of many researchers recently. However, most of
existing researches are based on an ideal assumption that the cloud server is
“curious but honest”, where the search results are not verified. In this paper,
we consider a more challenging model, where the cloud server would probably
behave dishonestly. Based on this model, we explore the problem of result
verification for the secure ranked keyword search. Different from previous data
verification schemes, we propose a novel deterrent-based scheme. With our
carefully devised verification data, the cloud server cannot know which data
owners, or how many data owners exchange anchor data which will be used for
verifying the cloud server’s misbehavior. With our systematically designed
verification construction, the cloud server cannot know which data owners’ data
are embedded in the verification data buffer, or how many data owners’
verification data are actually used for verification. All the cloud server
knows is that, once he behaves dishonestly, he would be discovered with a high
probability, and punished seriously once discovered. Furthermore, we propose to
optimize the value of parameters used in the construction of the secret
verification data buffer. Finally, with thorough analysis and extensive
experiments, we confirm the efficacy and efficiency of our proposed schemes.
