Research on data security and privacy protection methods in cloud computing environment

Abstract

Cloud computing has received widespread attention and application in the industry due to its strong computing power and large storage capacity. However, while users enjoy the convenience brought by cloud computing technology, they inevitably face the challenge of data security, and how to ensure the privacy security of data in the cloud environment has become an urgent problem. Therefore, this paper investigates the privacy protection methods of data security based on cloud computing environment. This paper first analyses the architecture of cloud computing and the current threats. Then, it focuses on the principles of AES and SM2 algorithms, and on this basis, a hybrid encryption data security privacy protection scheme is proposed by combining the SM2 algorithm with the AES algorithm. Through experimental tests, the results demonstrate that the scheme improves the computational efficiency of encryption and decryption while effectively protecting the privacy and security of data transmission in the cloud environment.
