Secure and efficient report garage and sharing through authenticated bodily devices remain challenging to attain in a cyber-physical cloud environment, particularly due to the variety of devices used to get right of entry to the offerings and records. Thus on this paper, we gift a light-weight identity-based totally authenticated information sharing protocol to offer at ease records sharing amongst geographically dispersed bodily gadgets and customers. The seasoned- posed protocol is verified to face up to selected-cipher text attack (CCA) beneath the hardness assumption of decisional-Strong Diffie- Hellman problem. We also evaluate the overall performance_of the proposed protocol with present facts sharing protocols in terms of computational overhead, communication overhead, and reaction time.
