Device networking authentication method based on blockchain

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a block chain-based equipment networking authentication method. Background technique [0002] The blockchain was originally a special distributed accounting technology designed by a person named Satoshi Nakamoto for Bitcoin (a digital currency). Bitcoin and the blockchain technology derived from it have introduced technologies such as signature system, consensus mechanism, and time stamps. The mutual cooperation between various modules perfectly solves the security risks caused by decentralization. Therefore, blockchain is not a brand-new Internet technology, but a clever integration of many existing technologies, such as asymmetric key signature, consensus mechanism, time stamp, hash algorithm, P2P communication, etc. Blockchain technology is based on a decentralized peer-to-peer network, combining cryptography principles, time series data and consensus mechanisms to ...

AI Technical Summary

Problems solved by technology

[0017] (2) Non-tamperable and encrypted security. The system adopts a one-way hash algorithm, and the newly generated blocks are advanced in strict time-linear order. For trying to rewrite or modify transaction records, its cost is very high

[0020] (1) If any problem occurs during the communication process, when the CA cannot make corresponding countermeasures, the two parties in the communication will not be able to solve the problem, resulting in the final problem being ignored;

[0021] (2) Once the CA is attacked, the entire authentication system will be greatly damaged, and in severe cases, the entire system will be paralyzed;

[0022] (3) If the attacker tampers with the information during the communication process, the two parties in the communication cannot know that the information has been tampered with

[0027] Through consulting the data, it is found that there is currently no public literature related to the method of using blockchain for device network authentication
