Safety authentication method, device and equipment based on block chain and storage medium

Abstract

The invention discloses a security authentication method, device and equipment based on blockchain, and a storage medium. The security authentication method based on the blockchain comprises the steps: obtaining user information, password information, authority information and related data value information of a to-be-authenticated node; generating encrypted information based on the user information, the password information, the authority information and the related data value information; issuing the encrypted information to a blockchain distributed account book, wherein the encrypted information is acquired and decrypted by the authentication object so as to determine an authentication result according to the user information, the password information, the authority information and therelated data value information; obtaining an authentication result, and determining whether the to-be-authenticated node passes security authentication or not according to the authentication result. According to the embodiment of the invention, a decentralized user authentication mechanism can be established, and the security of data storage and user authentication is enhanced.

Description

technical field [0001] The invention belongs to the technical field of network communication, and in particular relates to a block chain-based security authentication method, device, equipment and storage medium. Background technique [0002] At present, the big data center is mainly built on the basis of the Hadoop ecosystem. This ecosystem exposes the settings of the big data platform, making the big data containing massive data and potential value easy to attract hackers' attacks, and in the process of user use, Mainly, it is easy to have security problems in the process of identity verification, authorization and input verification. [0003] In the prior art, cloud computing technology is usually used to realize unified and centralized management of identity authentication of different application systems. Each application system no longer needs to care about the identity authentication process to solve the security issues of identity verification, authorization and oth...

AI Technical Summary

Problems solved by technology

[0006] (1) There are many nodes used in the distributed storage and calculation of big data. If a node is compromised, it will lead to a large amount of data leakage of this node and other nodes

[0007] (2) Once the central node that provides unified identity authentication service is compromised, it will cause the paralysis of identity authentication of all nodes

[0008] (3) When the number and location of nodes are dynamically adjusted, the traditional security protection measures for a single node must also be dynamically adjusted accordingly, resulting in a large workload for later operation and maintenance
