Abstract: With the rapid development of the Internet, Internet of Things (IoT) technology is widely used in people’s daily lives. As the number of IoT devices increases, the amount of data to be processed also increases. The emergence of cloud computing can process the data of IoT devices in a timely manner, and it provides robust storage and computing capabilities to facilitate data resource sharing. Since wireless communication networks are unstable and open, it is easy for attackers to eavesdrop, intercept, and tamper with the messages sent. In addition, authentication protocols designed for IoT-enabled cloud computing environments still face many security challenges. Therefore, to address these security issues, we propose an Intel software-guard-extensions (SGX)-based authentication key agreement protocol in an IoT-enabled cloud computing environment. The goal is to ensure data privacy and sustainable communication between the entities. Moreover, SGX can resist several well-known attacks. Finally, we show the security using the real-or-random model, ProVerif, and informal analysis. We also compare the security and performance of the proposed protocol with existing protocols. The comparison results show that our proposed protocol reduces the communication cost by 7.07 % compared to the best one among the current protocols and ensures sufficient security.
