Abstract

The invention discloses a device for assisting in realizing USB Key safety. The device is connected between a device for operating an on-line bank system and a USB Key and comprises an information receiving unit, a control unit and an information transferring unit, wherein the information receiving unit is used for receiving transaction data information sent by the on-line bank system; the controlunit is used for sending the transaction data information to the USB Key when confirming information of users is received; and the information transferring unit is used for receiving the transactiondata information after the USB Key carries out digital signing and returning the transaction data information to the on-line bank system. By using the device, the common USB Key can have the same safety property with the USB Key with a confirm key. Simultaneously, if the control unit can not normally receive the confirming information, only the device is replaced without changing , therefore, thecost is saved.

Description

technical field [0001] The present invention relates to the technical field of USB Key, in particular to a device and method for assisting in realizing USB Key security. Background technique [0002] USB Key is a hardware storage device with USB interface. The appearance of the USB Key is similar to that of an ordinary U disk, the difference is that it stores a single-chip microcomputer or a smart card chip. The USB Key has a certain storage space and can store the user's digital certificate and key. Using the key algorithm built in the USB Key can Realize the authentication of user identity. It provides high-strength two-factor authentication through hardware + PIN code to ensure the security of digital certificates.
