Abstract
With the rapid development of wireless communication technology, the Internet of Things is playing an increasingly important role in our everyday. The amount of data generated by sensor devices is increasing as a large number of connectable devices are deployed in many fields, including the medical, agricultural, and industrial areas. Uploading data to the cloud solves the problem of data overhead but results in privacy issues. Therefore, the question of how to manage the privacy of uploading data and make it available to be interconnected between devices is a crucial issue. In this paper, we propose a scheme that supports real-time authentication with conjunctive keyword detection (RA-CKD), this scheme can realize the interconnection of encrypted data between devices while ensuring some measure of privacy for both encrypted data and detection tokens. Through authentication technology, connected devices can both authenticate each other’s identity and prevent malicious adversaries from interfering with device interconnection. Finally, we prove that our scheme can resist inside keyword guessing attack through rigorous security reduction. The experiment shows that the efficiency of RA-CKD is good enough to be practical.
