Problems solved by technology

[0004] However, the inventor found in the process of implementing the present invention that at least the methods in the prior art have the following problems: in the traditional device authentication system, only the authentication information generated by the authentication server cannot guarantee the uniqueness of the user device. Because the authentication information sent by the authentication server to the user device may be hijacked or attacked by a third party

Embodiment 1

[0024] figure 2 It is a flow chart of a blockchain-based device authentication method provided in Embodiment 1 of this application. Such as figure 2 As shown, the method includes:

[0025] Step S210: Receive a device binding request sent by the user equipment, generate device binding information corresponding to the device binding request, and provide the device binding information to the user equipment.

[0026] In the embodiment of the present invention, in order to ensure the uniqueness of the user equipment that initiates the authentication request, before performing the authentication operation, the binding information of the user equipment needs to be stored in the smart contract of the block chain. Therefore, it is necessary to generate corresponding and unique device binding information for the device binding request sent by the user equipment, and return the device binding information to the user equipment, so that the user equipment can send the device binding in...

Embodiment 2

[0037] image 3 It is a flow chart of a blockchain-based device authentication method provided in Embodiment 2 of the present application, and the execution body of the method is preferably an authentication server. Such as image 3 As shown, the method includes:

[0038] Step S310: Set up the smart contract, and broadcast the smart contract to the blockchain.

[0039] Specifically, the preset smart contract is broadcast to the blockchain network in the form of blockchain transactions, and after verification by most nodes, the smart contract reaches a consensus on the blockchain network, and then the smart contract can run on the blockchain network. Among them, the structure of the above smart contract is divided into three parts, namely the smart contract blockchain account address, data part and program part, and the program part of the smart contract can realize three functions, one is to write data to the data part , which is used to perform data writing operations on ...

Embodiment 3

[0052] Figure 4 It is a flow chart of a blockchain-based device authentication method provided in Embodiment 3 of the present application, Figure 4 The execution subject of the shown method may be a user equipment. Such as Figure 4 As shown, the method includes:

[0053] Step S410: Send a device binding request to the authentication server, and receive device binding information returned by the authentication server according to the device binding request.

[0054] In this embodiment, in order to ensure the uniqueness of the user equipment that initiates the authentication request, before performing the authentication operation, it is necessary to perform a binding operation on the user equipment, and store the binding information of the user equipment in the smart contract of the block chain . Therefore, after the user equipment sends a binding request to the authentication server, the authentication server needs to generate corresponding and unique device binding info...

Abstract

The invention discloses a block chain based equipment certification method, a certification server and user equipment, and relates to the technical field of equipment certification. The method includes: receiving an equipment binding request sent by the user equipment, generating equipment binding information corresponding to the equipment binding request, and providing the equipment binding information to the user equipment; acquiring a first process running result generated by a smart contract, and sending a binding success message to the smart contract according to the first process running result; receiving an equipment certification request sent by the user equipment, and returning equipment certification information to the user equipment according to the equipment certification request; acquiring a second process running result generated by the smart contract, and performing certification on the user equipment according to the second process running result. Therefore, the block chain smart contract is used for saving the equipment binding information to make the equipment information not tampered, and the problems in the prior art are solved.

Description

technical field [0001] The present invention relates to the technical field of equipment authentication, in particular to a block chain-based equipment authentication method, authentication server and user equipment. Background technique [0002] Device authentication refers to the process of confirming the qualification of a device in a computer and computer network system, so as to determine whether the device has access and use rights to a certain resource, so that the access policy of the computer and network system can be implemented reliably and effectively. [0003] Such as figure 1 As shown, in the traditional device authentication system, assuming that the authentication server A needs to confirm the qualification of the user device B, the main process is as follows: 1.1, the user device B sends a device authentication request to the authentication server A; 1.2, the authentication server A returns the authentication information To user equipment B, wherein the aut...
