Embodiment 1

[0033] As shown in Figure 1, a multi-application KEY device with NFC function, the connection relationship of each functional module inside the device 1 is as follows: the cos control unit in the device is respectively connected to the test logic unit, the security logic unit, and the storage manager through the system bus , NFC unit and ISO7816 interface control unit are connected and exchange data. Among them, the storage manager is divided into ROM management, RAM management and EEPROM management to manage the on-chip ROM, RAM and EEPROM respectively; the test logic unit is used to test the internal circuit in production; the safety logic unit contains a computing coprocessor , to complete operations such as DES and 3DES; the NFC unit realizes NFC communication with external devices; the ISO7816 interface control unit is used to control the ISO7816 interface to achieve data exchange with peripherals that conforms to the ISO7816 specification. The storage manager is connecte...

Embodiment 2

[0037] As shown in Figure 4, the difference between the device of this embodiment and the previous example is that the ISO interface control unit in the previous example is changed into a USB interface control unit, and the system bus is also provided with a bus conversion unit; the general input / output port and The USB interface is respectively connected to the bus conversion unit through the peripheral bus, and is respectively connected to the external pins to realize the data exchange between the device and the peripheral; the USB interface control unit is used for mutual conversion between the system bus and the relevant data in the USB interface.

[0038] The storage manager is connected with ROM, RAM and EEPROM respectively through the system bus to manage them. ROM is used to store cos code; RAM is used to store information such as temporary variables and process data when the device is running; EEPROM is managed by cos and is used to store mobile certificates, power, pr...

Embodiment 3

[0040] As shown in Figure 5, on the basis of Embodiment 2, the present embodiment is further connected with a Flash chip on the system bus; a Flash management part is provided in the storage manager to manage the on-chip Flash.

Abstract

The related multi-application KEY device with NFC function comprises a cos control unit in the device connected all of a logic testing unit, a security testing unit, a memory manager and an interface unit by system bus; and a NFC unit connected with the control unit for data conversion. Wherein, the manager comprises different parts for ROM, RAM and EEPROM, and the external contact piece is packed on back and arranged as interface standard.

Description

technical field [0001] The invention relates to a mobile certificate dual-interface KEY device with an NFC function that can be used for encryption and authentication in security authentication occasions such as online banking. Background technique [0002] At present, with the use of special USBKEY in online financial transactions, the security of online financial transactions has been greatly guaranteed. However, these special-purpose USBKEY products have single functions and relatively strict requirements for use conditions, which cannot meet the diverse and multi-occasion needs of users. In addition, the current short-distance wireless communication products and various contactless smart cards are only used in fields involving small amount of transactions when they are used in finance due to their poor security, such as small-value card swiping for buses, subways, and short-distance tickets. Consumption. Contents of the invention [0003] The purpose of the present i...
