| Abstract | Phrase search schemes over encrypted data are efficient methods for protecting users' data privacy in storage outsourcing systems. We analyze and improve two one-round phrase search schemes over encrypted data. One drawback of F. Kong's phrase search scheme is that it cannot support single-keyword search. We propose a modification and the improved scheme supports both single-keyword and phrase search. In M. Li's phrase search scheme, a simple unkeyed hash function is used instead of a keyed pseudo-random function. We present a security analysis and show that the usage of a keyed pseudo-random function can resist the leakage of some useful information. These phrase search schemes can be applied in cloud storage. |
