Abstract: Due to the poor attack resistance of traditional access identity authentication control systems, 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 analyze the functionality of the model. As to the device, we use the IoT device end to obtain device-related information. And as to the alliance chain network, we use the DPoS consensus mechanism to process the information obtained at the device layer for consensus. As to the application, we use an identity authentication control model combined with the consensus information, to determine identity authentication control permissions, thus completing the control of IoT blockchain access identity authentication. The experimental results show that the identity authentication control system studied can effectively achieve identity authentication control, and the success rate of attacks for the studied system is low, indicating that the studied system has strong anti-attacking ability.

摘要： 由于传统访问身份认证控制系统存在抗攻击性差的问题,文中设计了基于DPoS(Delegated Proof of Stak)共识机制的物联网区块链访问身份认证控制系统,构建区块链访问身份认证控制模型,并对模型的功能进行分析。在设备层利用物联网设备端获取设备相关信息,在联盟链网络层利用DPoS共识机制对设备层获取的信息进行共识处理,在应用层中运用身份认证控制模型,结合达到共识的信息,裁决身份认证控制权限,从而完成物联网区块链访问身份认证的控制。实验结果表明,所研究的身份认证控制系统能够有效实现身份认证控制,并且被攻击成功率较低,说明系统具有较强的抗攻击性。
