Abstract

The invention relates to a blockchain-based industrial Internet of Things device identity authentication and security interaction method, which presets trust information for the industrial Internet of Things device, and then the device generates identity public and private key information, and uses the device software and hardware information to generate the Industrial Internet of Things The unique fingerprint ID of the device; use the preset trust information to sign the public key + ID of the device and send it to the identity service node on the blockchain. The information is written into the blockchain; the industrial Internet of Things device uses the identity private key to sign the business data and sends it to the business interaction party. Key, use the sender's public key to verify the above signature information; Industrial Internet of Things devices intelligently configure access rights between devices through smart contracts, prevent devices that do not comply with access rules from interacting, and ensure mutual access between authorized devices.

Description

technical field [0001] The invention belongs to the field of information security industrial Internet of Things device identity authentication, and in particular relates to a block chain-based industrial Internet of Things device identity authentication and a security interaction method. Background technique [0002] With the development of "Internet +" smart devices and the further popularization of IoT technology, the number of industrial IoT devices has grown rapidly. The access of a large number of industrial Internet of Things devices puts forward more requirements for the identification and interaction of devices. The trusted identity authentication and secure access control of industrial Internet of Things devices are the prerequisites for building a highly available and secure Industrial Internet of Things. The interaction process between industrial Internet of Things devices urgently needs to improve information sharing and collaborative operation capabilities. The...
