Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] figure 2 It shows a schematic structural diagram of a USBKey provided in the embodiment of the present invention. It can be seen from the figure that the USBKey mainly includes the USBKey chip 1, the micro control unit MCU of the USBKey, and the USBKey used for connecting the USBKey to an external terminal device. Among them, the USBKey interface includes USB interface 2 and non-USB interface 3. When the USBKey is connected to the external terminal device through the USB interface 2, the working mode of the USBKey is the USB working mode. When the USBKey is connected to the external terminal through the non-USB interface 3 When the device is connected, the working mode of USBKey is non-USB working mode. Wherein, the non-USB interface may be a Bluetooth interface, an audio interface, or an NFC interface.

Abstract

The present invention discloses a USBKey, belonging to the field of security authentication technologies. The USBKey includes a USBKey chip (1) and a USBKey interface. The USBKey interface includes a USB interface (2) and a non-USB interface (3). The USBKey also includes a working mode determination module (4) for determining a working mode of the USBKey and an interface switch module (5) for communicating the USBKey chip (1) with the USBkey interface corresponding to the working mode according to the working mode of the USBkey. The working mode determination module (4) and the interface switch module (5) are each connected with the USBKey chip (1). Through adoption of the USBKey, communication switch between the USBKey chip and different USBKey interfaces is realized, the USBKey chip, namely MCU input and output pins, are saved, and hardware resources are saved.

Description

technical field [0001] The invention relates to the field of security authentication equipment, in particular to a USB key. Background technique [0002] USB Key (hereinafter referred to as U-shield) is an identity authentication device widely used by online banking users to ensure the security of user accounts. At present, this kind of equipment has been more and more widely used in occasions requiring identity authentication, such as online banking and e-commerce. [0003] The traditional USB-shield is called a USB-shield because it uses a single USB communication interface for personal computers such as PCs. In recent years, with the rapid development of the mobile Internet, more and more mobile devices (such as mobile phones, tablet computers, etc.) Can not meet people's needs. In order to solve this problem, the U-shield function has been expanded with more communication interfaces, such as Bluetooth interface, audio interface, NFC interface, etc. In order to realiz...
