Title:
Efficient Public Key Encryption with Keyword Search Schemes from Pairings
Authors: Chunxiang Gu, Yuefei Zhu, Yajuan Zhang
Abstract:Public key encryption with keyword search (PEKS) enables
user Alice to send a secret key T_W to a server that will enable
the server to locate all encrypted messages containing the keyword
W, but learn nothing else. In this paper, we propose a new PKES
scheme based on pairings. There is no pairing operation involved
in the encryption procedure. Then, we provide further discussion
on removing secure channel from PKES, and present an efficient
secure channel free PKES scheme. Our two new schemes can
be proved secure in the random oracle model, under the appropriate
computational assumptions.
