Research on data query and encryption scheme based on cloud computing
Sun Huijie · Computer Engineering and Applications Journal · 2013
Data query and data encryption technology in the cloud computing is a current research hot. Aiming at the problems of the existing schemes, this paper proposes an improved data query and encryption scheme. For data searching, an identification management model is established firstly, and then an identity differentiating algorithm is proposed based on jurisdiction to achieve the optimal distribution between the system resources and the ID quantity. For data encrypting, we propose a calculative encrypting method named CES, which can support the fuzzy retrieval and the basic computing operation, moreover, this method also can effectively protect the privacy data for users. The simulation results show that, our scheme is effective, and the performance is better than the traditional methods in terms of the decrypting, storage and communication cost.
