| Abstract: | The cloud service mode has obtained broad application space with the rapid development of cloud computing technology. Such mode has endowed users with incomparable computing power and storage space. Privacy security of users is a the primary problem in the promotion and application of the service mode. How to guarantee both the privacy and availability of data in the process of data computation is a major problem, and as a key means to solve this problem, homomorphic encryption technique has been a hot subject in international and domestic academic circles in recent years. In this paper, the privacy security of cloud computing, the research progress of homomorphic encryption and the application of homomorphic encryption technique in privacy protection of cloud computing were introduced. The focus of this paper was the introduction and analysis of advantages and disadvantages of various homomorphic encryption schemes, and the future research direction was proposed. |
