A system of shareable keyword search on encrypted data

Abstract

Nowadays the cloud security becomes a significant issue: while the single user keyword search on encrypted data has been proposed, encrypting files before uploading scarifies the advantage of the convenience of sharing data with others on the cloud. We design a searchable encryption for the multi-user case. We combine the advantage of efficiency of the symmetric encryption with authentication of the asymmetric encryption to provide a secure and efficient system of shareable keyword search on encrypted data.
