Advances in Secure IoT Data Sharing

The proliferation of IoT devices on the Internet is currently in the billions, and projections anticipate that there will be 50 billion connected IoT devices in the IoT market by 2030. This rapid expansion will result in a substantial increase in data, which includes personal data, generated by these IoT devices. It is estimated that the data volume will reach 73.1 zettabytes by 2025. To fully realize the substantial benefits of the IoT, it is imperative to facilitate the responsible utilization and sharing of this data among various stakeholders. However, it is crucial to establish robust security and trust mechanisms to ensure data integrity and privacy during data sharing. Our objective is to summarize and assess the research efforts that address secure IoT data sharing. We systematically review the state-of-the-art techniques ensuring and preserving security in the IoT data-sharing environment through a systematic literature review (SLR) study. We pose three research questions, define selection
