Provably secure and
lightweight identity-based authenticated data sharing protocol for
cyber-physical cloud environment
Abstract:
Secure and efficient file storage and sharing
via authenticated physical devices remain challenging to achieve in a
cyber-physical cloud environment, particularly due to the diversity of devices
used to access the services and data. Thus in this paper, we present a
lightweight identity-based authenticated data sharing protocol to provide
secure data sharing among geographically dispersed physical devices and
clients. The proposed protocol is demonstrated to resist chosen-ciphertext
attack (CCA) under the hardness assumption of decisional-Strong Diffie-Hellman
(SDH) problem. We also evaluate the performance of the proposed protocol with
existing data sharing protocols in terms of computational overhead,
communication overhead, and response time.
