Identity Authentication Method of Internet of Things Devices Based on Blockchain Technology
Because different devices cooperate in the same area,and the devices are widely distributed and the application scenarios are complex,it is necessary to authenticate their identities,and the authentication method of Internet of Things devices based on blockchain technology is studied.Based on the inherent genes of devices in the Internet of Things,devices are classified according to different dimensional characteristics,and the identity characteristics of different devices in the Internet of Things are defined.Based on the blockchain technology,the features are processed,and the authentication request is encrypted by using the key pair method.Under the steps of dimension features,search request and information encryption,the identity authentication of Internet of Things devices is gradually completed,and the method design is completed.The experimental results show that the new method can achieve fast identity authentication with four groups of different IOT devices as test objects,and it can also complete fast identity authentication in attack mode,which has application value.
