However, blockchain technology adopts a decentralized network structure, where each IoT device has a unique identity  identifier, namely a private key and public key pair. This identity identifier helps to ensure the independence of the device in the network and improves the security of identity authentication."}]}],"pr":"822320fc1f5f2ad01c2fe7fbb08222927b7925a2ba3c721a77946dcb942cbc8a"}
