Abstract

A key and key handle generation method and system, and a smart key security device. The method comprises: receiving a registration instruction sent by a client; determining whether it is full for key storage; if it is full for key storage, selecting one of the stored keys, using the selected key identifier and combining same with a diversification factor to generate a key handle. The present invention can effectively solve the problem, of the key and key handle generation method provided in the prior art, that re-registration cannot be performed if the number of key pairs exceeds a maximum limit number.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method and system for generating a key and a key handle, and an intelligent key security device. Background technique [0002] At present, the relevant application specifications require unlimited registrations. This application process specification can comply with the FIDO specification, the QKey specification, or other similar application specifications. [0003] For example, according to the requirements of the FIDO specification, the FIDO USBKey application needs to support the function of unlimited registration, which means that in the registration command of FIDO, the KeyHandle returned by the USBKey can support an unlimited number, but the KeyHandle corresponds to an asymmetric private key. According to the smart key security The security of the device requires that the asymmetric private key must be stored in the USBKey, however, the key storage capac...
