Abstract

The invention discloses a block chain key management system and method. The system is provided with a transaction access device at a client end, is provided with a logic processing device, a secret key management device and a digital signature device at a server end, and is provided with a digital signature verifying device and a block chain device at a block chain end. Compared with a conventional block chain system, the system enables a transaction mechanism to keep public and private key pairs and establishes a one-to-one correspondence relation with client information, thereby solving theproblem of loss of private keys caused when a client keeps the private keys directly, and providing possibility for commercial use of block chains; and the client does not need to care what are blockchain public and private keys, only needs to pay attention to original user name passwords or hardware Ukey and the like issued by the mechanism, and does not need to change original operation 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, The private key is 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 acco...
