BIoMT: Blockchain for the Internet of Medical Things

The Internet of Things promises to connect more than 50 billion devices in a multitude of application domains. However, user privacy and security remain a major challenge in IoMT. In this paper, we present a work in progress for a lightweight blockchain based scheme aiming to secure the Internet of Medical Things (IoMT). The proposed approach consists of four main components: a cloud server, network cluster, medical facility, and smart medical devices. Each medical facility contains a “bolster”, a powerful computing device that operates as a gateway/server to support in-range smart medical devices. The bolster holds a private and secure block role. It is used to securely communicate with other blocks in the same blockchain. Experimental analysis shows that the proposed scheme presents a non-significant overhead; yet it brings major advantages to meet the standard security and privacy requirements in IoMT.
