A Note on One Privacy-Preserving Multi-Keyword Ranked Search Scheme over Encrypted Cloud Data

Zhengjun Cao and Lihua Liu

Abstract

We show that the scheme [IEEE TPDS, 25(1), 2014, 222-233] fails, because the introduced similarity scores do not represent the true similarities between the indexing vectors and the querying vector. The returned documents by the cloud server are not indeed related to the queried keywords.

Note: 3 pages
