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":"67f1a51b07f7d2906f841782ea96ef0b0d8d16343f15284eb1d7cf717dc38ece"}
