Lattice-based public-key encryption with conjunctive keyword search in multi-user setting for IIoT ; Journal: Cluster Computing, 2022, № 4, p. 2305-2316.
In this paper, we first propose a public key encryption with conjunctive keyword search (PECK) using lattices. Our PECK scheme provides efficient search over ...
To support multiple data users, a multi-user PECK scheme is also presented. The two schemes are proved secure against indistinguishable chosen keyword attacks ( ...
