Abstract: Internet of Medical Things (IoMT) plays an essential role in collecting and managing personal medical data. In recent years, blockchain technology has put power in traditional IoMT systems for data sharing between different medical institutions and improved the utilization of medical data. However, some problems in the information transfer process between wireless medical devices and mobile medical apps, such as information leakage and privacy disclosure. This paper first designs a cross-device key agreement model for blockchain-enabled IoMT. This model can establish a key agree- ment mechanism for secure medical data sharing. Meanwhile, a certificateless authenticated key agreement (KA) protocol has been proposed to strengthen the information transfer security in the cross-device key agreement model. The proposed KA protocol only requires one exchange of messages between the two parties, which can improve the protocol execution efficiency. Then, any unauthorized tampering of
