【Abstract】The 5G communication technology and edge computing jointly form 5G Edge and eliminate the constraints of Internet-of-Medical Things (IoMT) devices to facilitate several real-time healthcare services, including patient monitoring and diagnoses from anywhere. Nevertheless, the 5G Edge platform introduces risks of internal attacks to the data integrity and privacy of IoMT data. Hence, end users cannot trust data retrieved from the 5G Edge. This paper proposes a privacy-preserving search result certification framework for IoMT data on 5G and edge computing-assisted blockchain networks. The novelty of this paper is twofold. First, the proposed framework introduces a blockchain platform involving 5G Edge servers to ensure tamperproof data storage. In addition, an encrypted data storage model and a symmetric-key cryptography-based privacy-preserving search mechanism are developed for the 5G Edge blockchain. Second, the framework leverages an efficient multi-signature scheme to design a tamperproof search result certification mechanism for IoMT data on the blockchain of 5G Edge. Several experiments are conducted to evaluate the performance of the proposed framework.
