Abstract: A work method for a smart key device. A host machine acquires data from a trusted server via a browser and then transmits the data to a smart key device; the smart key device performs a signing operation when the data transmitted by the host machine is received and when a user confirmed by pressing a key and then returns a signing result to the host machine; and the host machine transmits data returned by the smart key device to the trusted server to verify the validity of the smart key device. This implements rapid authentication of user identity, thus allowing highly efficient, secure, and expedited online transactions.
