Abstract

The invention provides a key generation method and device and offline key generation equipment. The method comprises the steps of randomly generating a seed password through utilization of the offlinekey generation equipment in an offline state and receiving a payment password input by a user; carrying out encryption storage on the seed password according to the payment password through utilization of an encryption chip; generating first-level private keys of preset lengths according to the seed password and the payment password; and randomly generating a kth-level random number, for each kth-level private key, generating the preset number of (k+1)th-level private keys according to the kth-level private key and the kth-level random number, wherein the k is greater than or equal to 1. According to a plurality of levels of private keys generated through application of the method, after the private keys are distributed, departments owning upper-level private keys can generate lower-levelprivate keys independently, so domination and management can be carried out on assets of lower-level departments.

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...
