In the complex landscape of cyber-physical cloud environments, achieving secure and efficient file storage and seamless sharing, especially with authenticated physical devices, is an ongoing challenge. This complexity is compounded by the variety of devices accessing these services and data, each with their own security considerations. To address this challenge, this paper presents a new lightweight identity-based authenticated data sharing protocol. This protocol has been carefully designed to facilitate secure data sharing between physically distributed devices and clients, bridging geographic gaps without compromising security. Through rigorous analysis, the proposed protocol is robust against Chosen Cryptographic Attacks (CCA), enhanced by the hardness of the decision-based and robust Diffie-Hellman (SDH) problem. In addition, the performance of the protocol is fully evaluated against existing data sharing protocols, considering computational overhead, data transmission cost, and response time, to provide a comprehensive understanding of its performance in real-world scenarios.
