摘要
Public key encryption with keyword search (PEKS) is one of searchable encryption mechanisms. It not only provides user to retrieve ciphertext by keyword but also protects the confidentiality of keyword. In the past, many PEKS schemes based on different cryptosystems were proposed. Recently. Zheng et al. proposed a certificateless based PEKS scheme called CLKS. In this paper, we show that Zheng et al.' s CLKS scheme has some security flaw, i.e. their scheme suffered from an off-line keyword guessing attack.
