IDS-Chain: A Collaborative Intrusion Detection Framework Empowered Blockchain for Internet of Medical Things

The Internet of Medical Things (IoMT) has been integrated and deployed in the health care domain as it significantly facilitates medical services for both health care providers and consumers. The IoMT allows various medical devices to exchange data over different wireless communication technologies without the need for human intervention. The widespread adoption of such a technology increases the demand for designing efficient, reliable, and secure IoMT environments. Although IoMT significantly improves quality of medical services, maintaining security and privacy remain major challenges. This article proposes a collaborative intrusion detection framework empowered blockchain technology for protecting IoMT networks, called IDS-Chain. The IDS-Chain framework leverages fog computing to deploy security functions through distributed fog nodes to efficiently detect cyberattacks near data source. Blockchain is used to ensure data trust, integrity, and privacy, as well as to enable secure data exchange among distributed IDS entities.
