Design and Implementation of Internet of Things Information Security Transmission Based On PBFT Algorithm

Aiming at the security problems such as data theft, fraud and tampering in the information transmission process of the Internet of things, this paper studies the decentralized and trustless technology of Internet of things information transmission based on the blockchain technology through the super ledger Fabric blockchain platform, and proposes a technology for Internet of things transmission information security that uses the PBFT algorithm. Simulation results show that the algorithm effectively utilizes the redundant computing power in the network and improves the security of information transmission and fault tolerance of the system.
