Embodiment Construction

[0025] The following will be described in detail in conjunction with the accompanying drawings.

[0026] In the blockchain system, the core node generally refers to participating in the complete transaction process of the blockchain. After the node stores the complete blockchain data and the transaction is completed, it participates in the blockchain consensus and has the opportunity to complete the bookkeeping function to generate a new block. Such nodes are generally undertaken by workstations, servers or cloud services with better performance. In this example, the core node that can realize blockchain key storage and recovery is the management counter.

[0027] see figure 1 , which discloses a flowchart of a blockchain key storage and recovery method based on encryption entrustment technology in the present invention. it includes:

Abstract

The invention provides a block chain key keeping and recovery method based on the encryption entrustment technology and a block chain key keeping and recovery device thereof. The method comprises the registration phase: the user encrypts a user private key locally and puts forwards application for registration to a management counter, and the management counter encrypts user information including the user private key cipher and publishes the encrypted user encryption information and the corresponding user public key to the block chain; and the key recovery phase: in the key recovery phase, the management counter receives a key recovery request transmitted by the user, retrieves the user encryption information from the block chain through the user public key and decrypts the user encryption information and transmits the decrypted user information including the user private key cipher to the user, and the user performs local decryption to recover the key. The key encryption entrustment technology is introduced and the user is enabled to entrust the encrypted private key to the management counter to be saved, and the management counter does not know the real content of the private key so that backup and recovery of the private key are enabled to be more secure, and the user's rights can be protected.

Description

technical field [0001] The invention relates to a block chain system, in particular to a block chain key storage and recovery method based on encryption entrustment technology which solves the security of block chain key storage and recovery. Background technique [0002] Blockchain technology is a decentralized distributed ledger technology that originated from Bitcoin. Nodes, as participants in the blockchain system, each maintain a copy of the data. The nodes maintain the consistency of the backup database data through the consensus algorithm. Each account in the blockchain system consists of an address (public key) and a private key. The user controls the assets in the account by using the private key, which is the only data that proves the user's identity. The user's core assets can only be controlled through the private key, that is, only the signature of the private key can realize the confirmation of the transaction, so about the block The protection of the chain ...
