The Internet of Medical Things (IoMT) is an extended genre of the Internet of Things (IoT) where the collaborate to provide remote patient health monitoring, also known as the Internet of Health (IoH). Smartphones and IoMTs are expected to maintain secure and trusted confidential patient record exchange while managing the patient remotely. Healthcare organizations deploy Healthcare Smartphone Networks (HSN) for personal patient data collection and sharing among smartphone users and IoMT nodes. However, attackers gain access to confidential patient data via infected IoMT nodes on the HSN. Additionally, attackers can compromise the entire network via malicious nodes. This article proposes a Hyperledger blockchain-based technique to identify compromised IoMT nodes and safeguard sensitive patient records. Furthermore, the paper presents a Clustered Hierarchical Trust Management System (CHTMS) to block malicious nodes. In addition, the proposal employs Elliptic Curve Cryptography (ECC) to protect sensitive health records and is resilient against Denial-Of-Service (DOS) attacks. Finally, the evaluation results show that integrating blockchains into the HSN system improved detection performance compared to the existing state of the art. Therefore, the simulation results indicate better security and reliability when compared to conventional databases.
医疗物联网（IoMT）是物联网（IoT）的一种扩展形式，其中各部分协同工作以提供远程患者健康监测，也被称为健康物联网（IoH）。智能手机和医疗物联网设备有望在远程管理患者的同时，保持安全且可信的患者机密记录交换。医疗保健组织部署医疗保健智能手机网络（HSN），用于在智能手机用户和医疗物联网节点之间进行个人患者数据的收集和共享。然而，攻击者可通过医疗保健智能手机网络中受感染的医疗物联网节点获取患者机密数据。此外，攻击者还可通过恶意节点破坏整个网络。本文提出了一种基于超级账本区块链的技术，用于识别受损的医疗物联网节点并保护敏感的患者记录。此外，本文还提出了一种集群分层信任管理系统（CHTMS）来阻止恶意节点。此外，该方案采用椭圆曲线密码学（ECC）来保护敏感的健康记录，并能抵御拒绝服务（DOS）攻击。最后，评估结果表明，与现有技术相比，将区块链集成到医疗保健智能手机网络系统中可提高检测性能。因此，与传统数据库相比，仿真结果显示出更好的安全性和可靠性。
