Example Embodiment

[0049] The solution will be further explained below in conjunction with the drawings.

[0050] As attached figure 1 Shown is a schematic structural diagram of an embodiment of the present invention. A private key threshold backup, loss reporting, and recovery system based on a consortium chain includes a certification authority, multiple users, and consortium chain members, where all users and consortium chain members Equipped with a key card, the key card is issued by a certification body, and the public key and private key are stored in the key card; the user key card includes a master key card and several backup key cards. All key fobs can be referred to by key fob ID, and CA maintains information about each user ID.

[0051] The user is equipped with the corresponding blockchain client, with one or more public keys, and no blockchain service.

[0052] The members of the alliance chain are equipped with corresponding blockchain services. Each service has one or more public keys. ...

Abstract

The invention discloses a private key threshold backup, loss reporting and recovery system based on an alliance chain and a method thereof. The private key threshold backup, loss reporting and recovery system comprises an authentication mechanism, a plurality of users and alliance chain members, wherein each user and each alliance chain member are each provided with a secret key card; the secret key cards are issued by the authentication mechanism, and public keys and private keys are stored in the secret key cards; the user secret key cards comprise a main secret key card and a plurality of backup secret key cards, and user private keys are stored in a distributed mode in a secret sharing mode; and each alliance chain member carries a block chain service and the like. The secret key cardsare configured for the client, the alliance chain member and the certification authority respectively, and the private key is stored in the secret key cards and backed up through the block chain, andthe private key protection effect is good, and the private key loss reporting and recovering method is high in safety and rapid in operation, and the problems that in the prior art, private key recovery is poor in safety and the like can be effectively solved.

Description

technical field [0001] The present invention relates to the technical field of secret sharing, in particular to a private key threshold backup, loss report and recovery system and method based on an alliance chain. Background technique [0002] Blockchain is a brand-new distributed infrastructure and computing paradigm. It uses an ordered chained data structure to store data, uses consensus algorithms to update data, and uses cryptography to ensure data security. In blockchain-based transactions, ensuring the data security of transactions and the privacy of customers is a necessary condition for the further development of blockchain. For this reason, cryptography technology, especially public key cryptography, has been widely used in blockchain. The alliance chain is a branch of the blockchain, so it is also a distributed and decentralized public database. The difference from other chains is that it is aimed at members of specific groups and limited third parties. A pre-se...
