The invention discloses a device networking authentication method based on a blockchain for solving the single point failure problem existing in the current networking authentication method. The technical scheme is to deploy a blockchain network comprising a client, a submission node and a consensus node. By means of the non-tampering property of the blockchain, a device firstly registers on the blockchain before accessing the network, when the device A needs to access the network, the device sends a networking request of a device B that has accessed to the network, the device B compares the information of the device A in the networking request with the information of the device A stored in the blockchain to judge whether the identity of the device A is legal, a smart contract issues a token to the device A, a timestamp in the token ensures that the device A is valid within a certain period of time, and after the token expires, the device A needs to pass the identity authentication toaccess the network again. By adoption of the device networking authentication method disclosed by the invention, the single point failure problem existing in the traditional networking authenticationmethod can be avoided, the legality of the identity of the device is ensured, and the security of the network is improved.
