The installation of the hardware encryption module in the wireless data card can realize the function integration of network authentication, identification, data hardware encryption transmission and wireless internet access, and can provide the functions of hardware data encryption and authentication and identification of a user identity when the user accesses the internet, thereby enhancing the security of the internet surfing with convenient use.
Description
Technical field
The utility model relates to communication technical field, relates in particular to a kind of wireless data card with hardware data encryption and subscriber identity authentication authentication function.
Background technology
Wireless data card is the mini equipment that the user is used for carrying out RFDC, and it can have zone and the Internet connection that radiophone signal covers; USB Key (hardware digital certificate carrier) is a kind of hardware device of USB interface, its built-in single-chip microcomputer or intelligent card chip, certain memory space is arranged, can store user's private key and digital certificate, utilize the authentication of the built-in public key algorithm realization of USB Key user identity.Because private key for user is kept in the coded lock, make in theory in any way and all can't read, therefore guaranteed the fail safe of authentification of user.
But prior USB KEY product can only provide the authentication function, but does not have wireless networking capabilities, need could use on the computer of networking; Existing wireless data card can only provide wireless networking capabilities for portable computer, but functions such as data hardware encipher and subscriber identity authentication authentication can't be provided simultaneously.
The utility model content
The utility model provides a kind of wireless data card, and when wireless networking capabilities were provided, having solved to provide data hardware encipher and identity authentication function.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of wireless data card, comprise the hardware encryption module and the wireless communication module that connect by standard communication interface, and the interface section that is connected with exterior terminal.
The beneficial effects of the utility model are: at the wireless data card built-in hardware encryption module, realize the function and wireless networking capabilities combining on data card of network authentication, authentication and the transmission of data hardware encipher, in wireless user's online, provide hardware data to encrypt and the subscriber identity authentication authentication function, improve Internet Security, easy to use.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described wireless communication module comprises the radio frequency part that is connected with wireless network, and baseband portion; Wherein, described baseband portion is connected with exterior terminal by described interface section, and is connected with hardware encryption module by described standard communication interface.
The beneficial effect that adopts above-mentioned further scheme is to need not extra USB-HUB (hub hub) chip, but create a logical channel by the baseband portion of wireless communication module, be responsible for being connected of exterior terminal and hardware encryption module, finish the instruction transparent transmission of terminal to hardware encryption module, save cost, more reliable.
Further, described standard communication interface is UART interface, SPI interface or I
2C interface.
Further, described exterior terminal is notebook computer, palmtop PC, 3G mobile or portable media player.
Further, described interface section is ExpressCard interface or USB interface.

Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model work schematic diagram;
Fig. 3 is the utility model workflow diagram.
Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
As shown in Figure 1, wireless data card of the present utility model comprises wireless communication module, hardware encryption module.Wireless communication module is by external interfaces such as ExpressCard, USB, with exterior terminal such as notebook computer, palmtop PC, 3G mobile, PMP (Portable Media Player, portable media player), waits connection.
Wherein, hardware encryption module is the intelligent card chip with the close algorithm special circuit of asymmetric arithmetic engine and state, and critical data is carried out encrypting storing, and the protection of maltilevel security mechanism prevents leakage of data, and the subscriber identity authentication authentication function is provided.
The utility model with hardware encryption module design wireless data card in, be bridge joint with wireless communication module on the data card interior circuit board, realize communicating by letter of hardware encryption chip and exterior terminal side.The radio frequency part of wireless communication module is finished and being connected of wireless network.
The baseband portion of wireless communication module is connected by external interfaces such as USB, ExpressCard with the exterior terminal side, and this connection is used for the transmission of order, data and the power supply of data card; Simultaneously, the baseband portion of wireless communication module and hardware encryption chip are by standard communication interface, as UART, SPI, I
2Interfaces such as C carry out order and data interaction.
The baseband portion of wireless communication module is created a logical channel, is responsible for being connected of exterior terminal and hardware encryption module, finishes the instruction transparent transmission of terminal to hardware encryption chip, its work schematic diagram as shown in Figure 2:
Exterior terminal drives by wireless data card and sends the AT instruction;
The baseband portion of wireless communication module is judged by the distinctive mark position of judging the AT instruction, if any position, distinctive mark position, then passes through the hardware encryption module sheet, as the no marks position, then is that common AT instructs by wireless communication module by oneself.
As shown in Figure 3, the flow process that adopts wireless data card of the present utility model to surf the Net is as follows:
The user inserts equipment or terminal such as notebook computer, palmtop PC, 3G mobile, PMP etc. with wireless data card;
The user normally surfs the Net by wireless data card; At this moment, wireless communication module is not set up any connection with encrypting module, and encrypting module enters sleep pattern automatically; Wireless communication module and communication between terminals are equal to common wireless data card and communication between terminals fully;
When the user landed some appointed website and enters the specific region, end side was initiatively initiated network authentication, needed the hardware encryption module side to finish the subscriber identity authentication authentication.At this moment, wireless communication module carries out data penetration transmission as the bridge between terminal and the encryption chip.
After the identification authentication authentication of user by hardware encipher, wireless data card and specific region UNICOM, can realize as required network data normal mutual or with after the data encryption normally alternately.
As the user after the authentication of the identification authentication by hardware encipher, wireless data card can't with specific region UNICOM.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
