A blockchain key management system and method

Abstract

The invention discloses a block chain key management system and method. The system is provided with a transaction access device at the client end, a logic processing device, a key management device and a digital signature device at the server end, and at the block chain end Equipped with a data verification device and a block chain device; compared with the conventional block chain system, the present invention trusts the public-private key pair by the trading organization, and establishes a one-to-one correspondence relationship with the customer information, which solves the problem of direct storage by the customer. The problem of private key loss provides the possibility for blockchain commercial use. Customers don't need to care about the public and private keys of the blockchain, they only need to pay attention to the original user name password or the hardware Ukey issued by the organization and other media, and there is no need to change the original operating habits.

Description

technical field [0001] The invention belongs to the field of computer systems, and in particular relates to a block chain key management system and method. Background technique [0002] The blockchain uses a variety of cryptography mechanisms to encrypt and decrypt data. The basis of the ownership verification mechanism is an asymmetric encryption algorithm. The asymmetrically encrypted public-private key pair in the blockchain is the cornerstone of building the entire trust system: the public key is used to express the address, Private keys are used to sign transactions. However, the public-private key pair has problems such as difficulty in storage. The public-private key pair can be stored in the form of plain strings, text, certificates, hardware Ukey, etc., but no matter how it exists, customers may lose the private key such as losing the media or forgetting the Ukey pin code. The possibility of control exists. However, the blockchain platform expresses customer accoun...

Problems solved by technology

However, the public-private key pair has problems such as difficult storage. The public-private key pair can be stored in the form of plain strings, text, certificates, hardware Ukey, etc., but no matter how it exists, customers may lose the private key such as losing the media or forgetting the Ukey pin code. The possibility of control exists. However, the blockchain platform expresses customer accounts or wallets through public key addresses. Once the control of the private key is lost, it will no longer be able to control the corresponding assets.
