Blockchain access authentication method and device, storage medium and electronic device

Abstract

The invention discloses a blockchain access authentication method and device, a storage medium and an electronic device, wherein the method comprises the following steps: obtaining an access request of a first account, wherein the access request is used for the first account to request to access a service blockchain node; responding to the access request, and determining a first access authority of a role belonging to the first account based on the permission data saved on the target blockchain node, wherein the data writing permission of the target blockchain node is closed after the saved permission data are written; in the case that the first access permission indicates that the first account is allowed to access the service blockchain node, the status of the business blockchain node isset to allow the first account to access. The blockchain access authentication method and device in the present invention solve the technical problem that the security of the permission data in the related art is low.

Description

technical field [0001] The present invention relates to the field of the Internet, in particular, to an authentication method and device for blockchain access, a storage medium, and an electronic device. Background technique [0002] Since the launch of the Bitcoin system, decentralized cryptocurrencies represented by Bitcoin and its derivative altcoins have received widespread attention. The feature of this currency system is to build a distributed shared ledger based on the block chain, so as to ensure the safety, reliability and decentralization of the system operation. Blockchain refers to a technical solution for collectively maintaining a reliable database through decentralization and trustlessness. This technical solution mainly allows any number of nodes in the participating system to associate a series of data blocks generated using cryptographic methods. Each data block contains all information exchange data of the system within a certain period of time, and gener...

Problems solved by technology

[0003] Authority management is the core content of the blockchain system. Due to the huge number of users and the large number of blocks in the blockchain system, the authority management technology in related technologies has the problems of large resource consumption, low authority control efficiency, and low security. For example, The access list control method manages rights through the list. A simple access list is an array composed of users and resources. When the amount of data is huge, the rights management is inefficient and easy to be tampered with; , the access control of user behavior is enforced, the user cannot change the security level or the security attribute of the object, the resource consumption is large, and the authority control efficiency is low

[0004] For the above problems, no effective solution has been proposed
