Abstract

The present application relates to a key generation method, device, and offline key generation device. The method includes: randomly generating a seed password through the offline key generation device in an offline state, and receiving the payment password input by the user; , encrypt and store the seed password according to the payment password; generate a first-level private key with a preset length according to the seed password and the payment password; randomly generate a kth-level random number, for each k-th level private key, generating a preset number of k+1th level private keys according to the kth level private key and the kth level random number, wherein k is greater than or equal to 1. In this way, among the multiple levels of private keys generated by the above method, after the private key is distributed, the department that owns the private key of the upper level can also independently generate the private key of the lower level, so as to realize the control and management of the assets of the lower level department.

Description

technical field [0001] This application relates to the technical field of blockchain virtual tokens, in particular, to a key generation method, device and offline key generation equipment. Background technique [0002] With the development of decentralization and blockchain technology, virtual tokens such as Bitcoin are more and more widely used, and the safe use and asset management of virtual tokens are getting more and more attention. In some asset management scenarios, for example, in the asset management of companies with multiple hierarchical departments, assets need to be managed hierarchically, and the upper-level department needs to be able to understand and control the use of assets by the lower-level departments. However, in the blockchain virtual tokens in the prior art, the user generates the corresponding public key through his own private key to generate the asset address, and encrypts the transaction process through the private key, only to manage his own ass...
