Application of Data Encryption Technology in Cloud Computing

With the rapid development of computer technology, cloud computing has been widely used in all walks of life, but the consequent network security problems have become increasingly prominent. This paper introduces data encryption technology to study the security challenges in cloud computing. Firstly, the basic characteristics of cloud computing are analyzed, and the security vulnerabilities of cloud computing are discussed. This study examines the function of data encryption technology in cloud computing in light of these issues, and deeply analyzes the applications and solutions of technologies for symmetric and asymmetric encryption, technologies for link and end-to-end data encryption both and node data encryption technology, in order to provide a reference for improving data security in cloud computing environment. The proposed data encryption scheme not only ensures data security but also effectively reduces the impact of encryption on the performance of cloud computing, demonstrating high practicality and feasibility. The research in this paper offers fresh concepts and techniques for the field of cloud computing security and is of great significance for promoting the wide application of cloud computing technology.
