Data Security Strategies and Technologies for Robust Cloud Computing

Abstract With the widespread application of cloud computing in various fields, data security issues have become prominent. This study systematically reviews key data security technologies such as encryption, access control, and privacy computing in cloud computing environments, and analyzes their application scenarios and limitations. Quantitative evaluation of technical performance, security, and scalability through empirical analysis in industries such as finance and government. Research has found that cloud computing data security requires the construction of a dynamic collaborative technology ecosystem, and users and service providers have different security responsibilities under different cloud service models. The research results provide theoretical support for enterprises to formulate cloud security strategies and promote technological innovation, which helps to solve the contradiction between data security and business development, and promote the high-quality development of the cloud computing industry.
