Problems solved by technology

For private chains and alliance chains, if the operation behavior of the blockchain is not isolated and controlled or legally verified, private chains and alliance chains are usually easily attacked by malicious nodes with only a small amount of computing power and it is difficult to track the source of the attack. Data security Low
[0003] In the existing technology, methods such as network isolation, data encryption, and communication encryption are usually used to reduce the risk of private chains and consortium chains being attacked by malicious nodes with only a small amount of computing power. As a result, the private chain and the alliance chain are made public, and the data security in the private chain and the alliance chain is still low

Embodiment Construction

[0032] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0033] The blockchain is a decentralized distributed database system that is jointly maintained by all nodes in the blockchain network. It is composed of a series of data blocks generated based on cryptographic methods. Each data block is a block in the blockchain. a block. According to the order of generation time, the blocks are linked together in an orderly manner to form a data chain, which is vividly called a blockchain. The blockchain is generated and verified by its special blocks and transactions, and has unchangeable, unforgeable, and fully traceable security features.

Abstract

The invention provides an operation authority management method and device, a block chain node and a storage medium, and relates to the technical field of communication. The operation authority management method comprises the steps of determining a block for executing authority management; determining whether the operation behavior of the authority management object on the block chain is legal or not according to the intelligent contract stored in the determined block; and finally, when the operation behavior of the authority management object on the block chain is determined to be legal, allowing the authority management object to execute the operation behavior on the block chain, so that the leakage problem of the encryption password of the data does not exist, the attack of malicious nodes is also avoided, and the security of the data is improved.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular, to an operation authority management method, device, blockchain node, and storage medium. Background technique [0002] At the level of application scenarios, blockchains can be divided into public chains, private chains, and alliance chains. The public chain means that anyone can join the consensus and be able to read and write consensus data; the consensus of the alliance chain is controlled by some pre-selected blockchain nodes, and there are mutual cooperation and mutual trust between the blockchain nodes. relationship; and private chain means that the write permission is controlled by the initiator of the chain, while the readability is limited. For private chains and alliance chains, if the operation behavior of the blockchain is not isolated and controlled or legally verified, private chains and alliance chains are usually easily attacked by malicious no...
