Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. Note that the aspects described below in conjunction with the drawings and specific embodiments are only exemplary, and should not be construed as limiting the protection scope of the present invention.

[0031] Traditional centralized institutions, such as banks, can use real-name authentication and other means. If the USB-shield representing the user’s identity is lost or the password is forgotten, the system can re-bind a new USB-shield (private key) through account verification. Realize the freezing and recovery of relevant account assets, and recover digital assets to a certain extent. The account and the private key are logically bound, and the centralized bank operates under the requirements of risk control.

[0032]In order to solve the technical problems proposed by the present invention, the present invention refers to the idea of ​​...

Abstract

The invention discloses a block chain secret key recovering method based on a multi-party security computing technology, and a medium, for preventing the permission of a core node from being overlarge, allowing the backup and recovery of a private key to be safer, and thus protecting user rights. The technical scheme is as follows: the mandate and recovery of the block chain secret key are performed by using the multi-party security computing technology. A governmental agency with legal validity can be introduced to be networked with a third-party agent for verifying identity validity of the user, so as to effectively verify and endorse the user identity. On the basis of effective endorsing, the user and the secret key management service provider perform security cooperative computing on the private key, so that the private key of the user is backed up and recovered in an encrypted manner. According to the method provided by the invention, the user identity management can be achieved,the permission of the privilege node is minimized, and the user identity is effectively verified through introducing the third-party agent, and thus the requirement of secrete key mandate of the nodeuser is met.

Description

technical field [0001] The present invention relates to block chain technology, in particular to a block chain key recovery method. Background technique [0002] Blockchain technology is the underlying technology of the decentralized distributed ledger technology that originated from Bitcoin. It is a chained data structure that combines data blocks in a sequential manner in chronological order, and uses cryptography to The non-tamperable and non-forgeable way guarantees a decentralized distributed ledger. A node is the basic unit of a blockchain network. Generally, a node corresponds to a computer. As a participant in the blockchain system, each maintains a copy of data and can play different roles, such as sending transactions, verifying transactions, and keeping accounts. . 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 ...
