基于DPoS共识机制的物联网区块链访问身份认证控制系统OA

Due to the poor attack resistance of traditional access identity authentication control sys-tems,this article aims to design an IoT blockchain access identity authentication control system based on the DPoS consensus mechanism,build a blockchain access identity authentication control model and ana-lyze the functionality of the model.As to the device,we use the IoT device end to obtain device-related in-formation.And as to the alliance chain network,we use the DPoS consensus mechanism to process the in-formation obtained at the device layer for consensus.As to the application,we use an identity authentica-tion control model combined with the consensus information,to determine identity authentication control permissions,thus completing the control of IoT blockchain access identity authentication.The experimen-tal results show that the identity authentication control system studied can effectively achieve identity au-thentication control,and the success rate of attacks for the studied system is low,indicating that the stud-ied system has strong anti-attacking ability.
