Public key Encryption with Keyword Search (PEKS) enables user Alice to send a secret key TW to a server that will enable the server to locate all encrypted messages containing the keyword W, but learn nothing else. In this paper, the authors propose a new PEKS scheme based on bilinear pairings. There is no pairing operation involved in the encryption procedure and so the authors' new PEKS scheme is more efficient than the scheme of the researcher. Then, they provide further discussions on removing secure channel from PEKS and present an efficient secure channel free PEKS scheme.
