Abstract

The invention discloses a working method and device of an intelligent key device, related to the field of computer. The working method of the intelligent key device comprises the following steps: whenan instruction of creating a key file sent by an upper layer application is received, the key file is created, the key identification carried in the instruction of creating the key file is set as thefile name of the key file, and the location identification corresponding to the key identification is saved to a key retrieval table; when an instruction of generating a key pair sent by the upper layer application is received, the corresponding key file is found according to the location identification, the key pair is generated when judging that no key pair is in the key file, and the private key is saved; when a signature instruction sent by the upper layer application is received, the private key in the private key file is called to sign the signature data carried in the signature instruction and obtain the signature result, and the signature result is returned to the upper layer application. The technical scheme disclosed by the invention has simple logical structure, simple operation and small storage cost, which improves the user experience.
