Abstract: The rapid development of cloud computing technology makes the cloud service model has a vast application space, this model allows users to have the incomparable computing power and storage space and other advantages.In the cloud service mode, the privacy and security of users is the primary problem in their promotion and application. How to ensure the privacy of data while ensuring the availability of data is a major challenge in the process of computing data. Homomorphic encryption As a key measure to solve this problem, it has become a hot issue in recent years both at home and abroad.This paper introduces the research progress of cloud computing privacy security and homomorphic encryption, the classification of homomorphic encryption algorithms, the theory of security, the realization technology of homomorphic decryption scheme and the application of homomorphic encryption technology in cloud computing privacy protection. The advantages and disadvantages of homomorphic encryption schemes are introduced and analyzed, and the future research directions are put forward.
