MQDS for PKE through CCA in cloud environment

In this paper, a mutual query data sharing protocol (MQDS) to provide security for the authenticated user data among the distributed physical users and devices. The proposed data sharing protocol is designed to resist the chosen-ciphertext attack (CCA) under the hardness solution for the query shared-Strong Diffie-Hellman (SDH) problem. The evaluation of proposed work with the existing data sharing protocols in computational and communication overhead through their response time is evaluated.
