Abstract

Aiming at solving the security problems of data confidentiality and integrity in the traditional centralized Internet of things communication, data leakage and tampering caused by malicious users abusing communication functions in the Internet of things system, a data communication mechanism of Internet of things based on blockchain is proposed. Combined with the characteristics of blockchain, such as decentralization, immutability and auditability, the data exchange mechanism of Internet of things communication tunnel is proposed. Preventing malicious communication through communication tunnel management and control of data exchange between devices, and ensures data integrity in combination with digital signature technology. The security analysis shows that the mechanism has good security characteristics and meets the security requirements of Internet of things communication. Experiments on Ethereum show that compared with existing studies, this mechanism has less time overhead, indicating the feasibility and availability of this mechanism.
