Title:
Searchable Encryption with randomized ciphertext and randomized keyword search
Authors: Marco Calderini, Riccardo Longo, Massimiliano Sala, and Irene Villa
Abstract:The notion of public key encryption with keyword search (PEKS) was introduced to efficiently search over encrypted data. In this paper, we propose a PEKS scheme in which both the encrypted keyword and the trapdoor are randomized, so that the cloud server is not able to recognize identical queries. Our scheme is CI-secure in the single-user setting and TI-secure in the multi-user setting with multi-trapdoor.
