Private key storage method and device and related equipment

Abstract

The invention discloses a private key storage method and device, and related equipment. The private key storage method comprises the steps that a key negotiation application sent by a client is received, a corresponding key position is formulated according to the key negotiation application, a corresponding encryption key is generated at the key position, and the key position is a key position inan encryption machine; a private key of a target user sent by the client is received, and the private key is encrypted according to the encryption key to obtain an encrypted ciphertext corresponding to the private key; wherein the private key is used for signing, encrypting and decrypting transaction data in a target account so as to use virtual assets in the target account; and the encrypted ciphertext corresponding to the private key is sent to a trusteeship server, so that the trusteeship server stores the encrypted ciphertext corresponding to the private key. By adopting the embodiment ofthe invention, the user private key can be encrypted through the encryption machine, and the leakage of the user private key is effectively prevented, so that the security of the virtual assets of theuser in the blockchain network is ensured.

Description

technical field [0001] The present invention relates to the technical field of blockchain, in particular to a private key storage method, device and related equipment. Background technique [0002] Blockchain technology is an Internet technology based on P2P (Peer To Peer, peer-to-peer), which has the characteristics of decentralization, collective maintenance and high transparency. Among them, the blockchain address of the blockchain account can be calculated through the public key, and the private key can be used to authorize the signature of the transaction information in the blockchain account, that is, to confirm the validity of the transaction information and realize homomorphism Encryption and other functions. It can be seen that the use of a blockchain account is closely related to the private key, which is as important as the password of the centralized accounting system (Alipay, WeChat payment, etc.). If the key is lost, the user's blockchain account in the block...

Problems solved by technology

However, this method makes the third-party escrow organization directly know the user's private key, which easily leads to the leakage of the user's private key, so that the security of the user's private key in the third-party escrow organization cannot be guaranteed, and the user will also face the risk of virtual property being stolen
