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.
