Abstract – This paper explores the critical issue of data sharing security in cloud computing, driven by the increasing dependence on cloud-based infrastructures for data storage, processing, and management. It reviews the key challenges, strategies, and advancements in ensuring secure data exchange within cloud environments. The study addresses essential concerns such as data confidentiality, integrity, access control, and privacy protection, while examining potential threats, including unauthorized access, data breaches, and insider attacks. Various cryptographic methods, secure access protocols, and emerging technologies like blockchain and homomorphic encryption are analyzed for their role in strengthening security. Additionally, the paper underscores the significance of legal and regulatory frameworks in enforcing security measures and outlines future research directions to address existing gaps. This survey serves as a valuable resource for researchers and professionals seeking to navigate and mitigate the complexities of secure data sharing in cloud computing.
