Distributed device authentication protocol in internet of things blockchain environment

摘要

The present invention relates to a device distributed authentication system and method in an IoT blockchain environment. In the device distributed authentication system, each node stores information and details of the device for each step in the distributed hash table ('DHT') through a blockchain agreement for authentication in the IoT blockchain environment, and the user Access control or authentication for devices is requested from the blockchain network, and each node agrees and approves based on the stored history, and messages propagated by manufacturers, service providers, and users are multi-encrypted. Therefore, the device distributed authentication system according to the present invention cannot prevent forgery of authentication information or participation in a forged device, can prevent an attack caused by the takeover of a device, can prevent the user from taking ownership of a user, and a malicious user Will prevent the device from accessing the device
