Block chain access authentication method and device, storage medium and electronic device

Abstract

The invention discloses a block chain access authentication method and device, a storage medium and an electronic device. The method comprises the following steps: the control center acquires an access request sent by the first account for requesting to access the block chain data, verifies a user certificate carried in the access request, obtains the position of the authority information of the first account in the block chain from an index system, and sends the position of the permission information in the block chain to the permission management smart contract, the permission management smart contract reads permission information of the first account at the position of the permission information in the block chain, and authenticates a first function to be accessed by the first account by using the permission information, sends an obtained authentication result to the control center, and allows the first account to access the first function by the control center according to the authentication result or refuses the first account to access the first function by the control center according to the authentication result. According to the method and the apparatus, the technical problem of relatively low security of permission data in related technologies is solved.

Description

[0001] This case is a divisional case of the application with the application number 2018104047452, the application date is April 28, 2018, and the invention title is "Sound method and device, storage medium, and electronic device for blockchain access". technical field [0002] 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 [0003] 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 s...

Problems solved by technology

[0004] 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 problems such as 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

[0005] For the above problems, no effective solution has been proposed
