摘要：Z. A. Kissel proposed a verifiable single-phase phrase search scheme using symmetric encryption algorithm, which was proved non-Adaptively secure in the Semi-Honestbut-Curious (SHBC) model. We present a security analysis of Z. A. Kissel's scheme and show that the cloud service provider can obtain some new phrases' trapdoors and search outcomes based on the client's a phrase query. Additionally, we propose an improvement to simplify Kissel's scheme and enhance its security. © 2015 IEEE.
