Embodiment 1

[0042] figure 1 It is a schematic flow diagram of a blockchain-based IoT device identity authentication method.

[0043] Such as figure 1 As shown, in order to solve the above problems, the embodiment of the present invention provides a block chain-based IoT device identity authentication method, including the following steps:

[0044] IoT device initialization, generating device identity information and public key, private key, and address for accessing the blockchain network;

[0045] The IoT device invokes the trusted service, obtains the token required for device access, and sends the token and the address of the device to access the blockchain network to the blockchain node, where the trusted service is provided by the device operator;

[0046] The blockchain node obtains the device identity information of the IoT device through the token. If the acquisition is successful, the blockchain node sends GAS and device identity information to the device address. If the acquis...

Abstract

The invention discloses an Internet of Things equipment identity authentication method and system based on a block chain, and the method comprises the following steps: initializing Internet of Thingsequipment, and generating equipment identity information and a public key, a private key and an address which are accessed to a block chain network; the Internet of Things device calls a trusted service, obtains a token required by device access, and sends the token and the address of the device access block chain network to the block chain node; the blockchain node acquires the device identity information of the Internet of Things device through the token, if the acquisition succeeds, the blockchain node sends the GAS and the device identity information to a device address, and if the acquisition fails, the blockchain node sends alarm information to the outside; and the Internet of Things equipment compares the equipment identity information returned by the blockchain node with the equipment identity information generated by the Internet of Things equipment, and if the equipment identity information returned by the blockchain node is different from the equipment identity information generated by the Internet of Things equipment, the Internet of Things equipment sends alarm information outwards. The method and the device have the advantage that the security of the Internet of Things equipment accessing the blockchain network can be improved.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a block chain-based identity authentication method and authentication system for Internet of Things devices. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. From the perspective of application, blockchain is a distributed shared account book and database, which has the characteristics of decentralization, non-tampering, traceability throughout the process, traceability, collective maintenance, openness and transparency. These characteristics ensure the "honesty" and "transparency" of the blockchain, and lay the foundation for the creation of trust in the blockchain. [0003] IoT device identity authentication means that when IoT devices are connected to the network, the identities of these devices need to be identified an...
