Along with the fast development of network, network security has also received people's extensive concern, but present wireless Internet card only provides the mode of an online, can't combine with some certified products on the market, brings safe guarantee can't for the use of network.
The utility model content
The purpose of the utility model is to provide a kind of wireless Internet card, makes wireless Internet card that the mode of an online not only can be provided, and can accomplish authenticating user identification through wireless network.
For solving the problems of the technologies described above, the execution mode of the utility model provides a kind of wireless Internet card, and this wireless Internet card comprises the SD-KEY interface of the multi-functional data SD-KEY card that is used to peg graft;
The SD-KEY cartoon is crossed in the SD-KEY interface that is inserted on the said wireless Internet card, is included in the said wireless Internet card.
The utility model execution mode in terms of existing technologies, through SD-KEY is provided on wireless Internet card slot, so that the SD-KEY card is included in the wireless Internet card.Because the SD-KEY card is existing a kind of multi-functional data card; Possess functions such as KEY, storage and data encrypting and deciphering simultaneously; Blocking built-in security module provides various Secure Application through SD (safe digital card) interface, comprises authentication, digital signature, access rights control and data encrypting and deciphering etc.Therefore the wireless Internet card that carries the SD-KEY card of the utility model not only can provide the mode of an online, and can accomplish authenticating user identification through wireless network.
In addition, wireless Internet card also comprises Wireless Internet access module and communication interface, and the SD-KEY interface links to each other with communication interface respectively with Wireless Internet access module, and SD-KEY interface and Wireless Internet access module have interface channel each other.Further, this communication interface is a USB interface.Because USB interface has been a kind of general interface, all have USB interface in almost any communication equipment, therefore, with USB interface as with the connecting interface of external equipment, can make this wireless Internet card possess application scenarios widely.
In addition, the SD-KEY interface is embedded slot form, and promptly the SD-KEY card can be embedded in the wireless Internet card, to avoid increasing the volume of wireless Internet card, has guaranteed the easy to use of wireless Internet card.
Description of drawings
Fig. 1 is the structural representation according to the wireless Internet card of the utility model one preferred embodiments;
Fig. 2 is the spi bus topological structure sketch map according to the SD-KEY interface in the utility model one preferred embodiments;
Fig. 3 is the use flow chart according to the wireless Internet card in the utility model one preferred embodiments.
Embodiment
One preferred embodiments of the utility model relates to a kind of wireless Internet card.Have SD-KEY slot (being the SD-KEY interface) on this wireless Internet card, be used to insert the SD-KEY card, this SD-KEY card is supported one of following Secure Application or its combination in any: authentication, digital signature, access rights control, data encrypting and deciphering.
Specifically as shown in Figure 1.This wireless Internet card comprises: SD-KEY interface, Wireless Internet access module and communication interface.Wherein, the SD-KEY card can be through being inserted in the SD-KEY interface on the wireless Internet card.The SD-KEY interface links to each other with communication interface respectively with Wireless Internet access module, and SD-KEY card and Wireless Internet access module have interface channel each other.In this execution mode, Wireless Internet access module can adopt the 3G network access, and descending peak rate reaches 3.1M bps, and up peak rate reaches 1.8M bps, to guarantee to get online without being tethered to a cable faster speed.Communication interface is a USB interface.The interface of SD-KEY card adopts SPI (synchronous serial Peripheral Interface) communication protocol.
It will be understood by those skilled in the art that the spi bus system is a kind of synchronous serial Peripheral Interface, allow MCU (micro-control unit) and various ancillary equipment with serial mode communicate, exchanges data.The spi bus topological structure of the SD-KEY interface in this execution mode is as shown in Figure 2.Before sending each order, the SD-KEY card is selected through a chip selection signal.Chip selection signal continuously effective during whole SPI transmission command, response and data.The SPI interface uses 7 SD buses, and card begins to count the spi bus clock cycle when confirming chip selection signal.The marker bit of each data or order is arranged the line of demarcation of 8 clock cycle, and SPI message comprises order, response and data block sign.Communicating by letter by host computer control between wireless Internet card and the SD-KEY card, to begin each bus mutual through dragging down chip selection signal for main frame.
The use of the wireless Internet card in this execution mode mainly contains following steps:
(1) connects wireless network, carry out 3G and get online without being tethered to a cable;
(2) do the account authentication, in the SD-KEY slot, insert the SD-KEY card;
(3) through wireless Internet card visit SD-KEY card;
(4) user identity is carried out authentication;
(5) be used to complete the back and break off the SD-KEY card.
Idiographic flow is as shown in Figure 3, and in step 101, wireless Internet card is realized function of surfing the Net through the Wireless Internet access module that comprises.
Then, in step 102, wireless Internet card is opened the function of SD-KEY card.
Then, in step 103, the user inputs information such as user name, password to PC (personal computer).
Then, in step 104, PC sends to user name, password in the server.
Then, in step 105, produce random number by server and send to PC.
Then, in step 106, PC sends to wireless Internet card with random number.
Then, in step 107, wireless Internet card sends to PC after with random number encryption.
Then, in step 108, PC sends to server with the encrypted result of random number.
Then, in step 109, server returns to PC with authentication result.
Be not difficult to find, in this execution mode,, can the SD-KEY card be inserted in the wireless Internet card through SD-KEY is provided on wireless Internet card slot.Because the SD-KEY card is existing a kind of multi-functional data card; Possess functions such as KEY, storage and data encrypting and deciphering simultaneously; Blocking built-in security module provides various Secure Application through the SD interface, comprises authentication, digital signature, access rights control and data encrypting and deciphering etc.Therefore the wireless Internet card that carries the SD-KEY card of the utility model not only can provide the mode of an online, and can accomplish authenticating user identification through wireless network.
And, because USB interface has been a kind of general interface, all have USB interface in almost any communication equipment, therefore,, can make this wireless Internet card possess application scenarios widely with the connecting interface of USB interface as this wireless Internet card and external equipment.
In addition, what deserves to be mentioned is that the SD-KEY interface in this execution mode is embedded slot form, promptly the SD-KEY card is embedded in the wireless Internet card, can avoid increasing the volume of wireless Internet card, has guaranteed the easy to use of wireless Internet card.
Above-mentioned each execution mode is a specific embodiment of realizing the utility model, and in practical application, can be in form with on the details it is done various changes, and do not depart from the spirit and the scope of the utility model.
