Re-appointment, Jianhua, Sun Huijie

The technology of data search and encryption under cloud computing environment is a hot topic in the present research. In view of the shortcomings of existing schemes, an improved data search and encryption scheme is proposed in this paper. In the area of data lookup, in this paper, the identity management model is established, and then the identity-based authentication algorithm is proposed to realize the optimal assignment between the system resources and the number of identities. In data encryption, a computational encryption scheme CES is proposed, which can support fuzzy retrieval of cloud data and basic arithmetic operation, Effectively protects the user's sensitive data with privacy. The simulation results show that the proposed scheme is effective, and it is superior to the traditional method in addition, decryption performance and storage and communication overhead.
