Method, apparatus, system, storage medium, and electronic device for securely accessing block chain

Abstract

The present disclosure proposes a method, an apparatus, a system, a storage medium, and an electronic device for securely accessing a block chain. The method comprises: preparing a new node accessingthe blockchain network to obtain endorsement data obtained by the trusted node preset in the block chain network using the private key to sign the target node public key, and performing signature verification on the endorsement data, if the signature After the verification is passed, it is determined that the identity authentication of the target node is successful, and the target node queries thepermission right of the new node's public key corresponding to the account address in the permission preset by the block chain network, and determines the new permission according to the checked permission. Whether the identity authentication of the node is successful. Therefore, the two-way authentication of the new node and the target node of the present disclosure directly utilizes the publicand private keys of the node of the block chain network node, and does not require a centralized third party to participate in the digital certificate, thereby avoiding the high complexity brought bythe digital certificate issuance. Secure access between nodes in the block chain network.

Description

technical field [0001] The present disclosure relates to the field of computers, and in particular to a method, device, storage medium and electronic equipment for safely accessing blockchain. Background technique [0002] Blockchain is a technical solution for collectively maintaining a reliable database in a decentralized manner. In the blockchain, nodes are connected to each other through a P2P (Peer-to-Peer, peer-to-peer) network. [0003] In the current blockchain technology, when a node (for example, a new node, including various terminals, blockchain light nodes, blockchain full nodes, etc.) accesses the target node on the blockchain network, it will not verify The legitimacy of the target node, the target node will not verify the legitimacy of the node. However, in some scenarios that require high information security, this access method may lead to the leakage of key information. For example, multiple organizations such as banks and enterprises participate in a b...

AI Technical Summary

Problems solved by technology

The traditional identity authentication method is generally realized by mutual transfer of digital certificates issued by a third-party organization between the two parties. This traditional identity authentication method has the problems of excessive centralization and high complexity of digital certificate issuance, and is not suitable for decentralized blockchain network
