Abstract

The invention discloses a blockchain key management method, comprising the steps of: monitoring whether there is a key management interface call request initiated by a blockchain node; if so, establishing a communication channel with the blockchain node and encrypting the communication channel; when the key management interface is an encryption service interface, receiving the node private key plaintext sent by the blockchain node through the communication channel, and encrypting the node private key plaintext to obtain the node private key ciphertext; when the key management interface is an decryption service interface, receiving the node private key ciphertext sent by the blockchain node through the communication channel, and decrypting the node private key ciphertext to obtain the nodeprivate key plaintext; and sending the node private key ciphertext obtained by encryption or the node private key plaintext obtained by decryption to the blockchain node by the communication channel.The invention also discloses a key management device, a blockchain key management system and a computer readable storage medium. The invention improves the security of the private key management of the blockchain node and reduces the maintenance cost.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a block chain key management method, a key management device, a block chain key management system, and a computer-readable storage medium. Background technique [0002] In the existing technology, blockchain nodes will generate public and private key pairs representing node identities. Among them, the following two methods are usually used to store and manage the private key: one is to save the private key of the blockchain node in plain text Locally; the second is to encrypt the private key of the blockchain node with a local symmetric key and store it locally. [0003] The first method is not encrypted and stored, and does not carry out key protection, so the private key is easily leaked and the security is low. In the second method, although encryption is performed, the encryption key of the private key is stored locally, so the security is still low. At the same...
