Detailed Description
The embodiment of the application provides a method and a system for accessing a card key to a computer, which are used for solving the problem that the card key is difficult to access the computer under the condition that the computer is not provided with a reader.
In order to make the objects, features and advantages of the present application more comprehensible, the technical solutions in the embodiments of the present application are described in detail below with reference to the accompanying drawings, and it is apparent that the embodiments described below are only some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The method for accessing the card key into the computer can be applied to a system for accessing the card key into the computer, the structural schematic diagram of the system is shown in fig. 1, the computer (PC) and the mobile device can be in communication connection in a wired or wireless mode such as USB, WIFI, bluetooth and the like, and the mobile device and the card key can be in wireless communication connection through a Bluetooth interface or an NFC interface. The mobile device in the application can be a smart phone, a tablet personal computer and other devices. Wherein fig. 2a and 2b show the front and back structural views of the card key. The card key may have a chip 01 and physical keys 02 disposed thereon. The chip 01 is used by swiping a card when the card key is used as a functional card such as a bank card. Regarding the physical key 02, when the mobile device requests to establish a link to the card key, the user may be required to press the physical key 02 to perform request confirmation, so as to improve the security of the card key, which will not be described in detail in the following embodiments.
Referring to fig. 3, a method for accessing a card key to a computer according to the present application is described in detail below by an embodiment, and includes:
301. the mobile device scans the card key;
302. if the card key is scanned, the mobile equipment generates and sends first information to the computer;
303. if the computer monitors the first information sent by the mobile equipment, generating a connection request according to the first information;
304. the computer sending the connection request to the mobile device;
305. the mobile equipment receives a connection request from the computer, and establishes a transit communication link between the computer and the card key according to the connection request.
For the above step 301, the mobile device may be pre-installed with an application program B (APP B), and the application program B executes the program control related to the mobile device in this embodiment. In performing step 301, application B initiates a bluetooth search or NFC search function on the mobile device, scanning for the presence of accessible bluetooth devices or NFC devices, in particular card keys, around the mobile device.
For step 302 above, if the mobile device scans the card key, a first message is generated and sent to the computer. It will be appreciated that the mobile device may have previously established a communication connection with the computer to send the first information to the computer. Alternatively, the mobile device may generate a broadcast message as the first message, send the first message out by broadcasting, and monitor the broadcast message by the computer and acquire the first message.
In particular, when the first information is broadcast information, the broadcast packet may be a UDP connectionless packet, and the packet format thereof is as follows:
| length (byte) | 32 | 32 | 6 | 4 | rssiLength |
| Value of | app id | name | mac | rssiLength | RSSI |
In the packet format shown in the above table, app ID refers to the unique ID of the application program that the mobile device generates the packet, i.e., the ID of application program B in the above application scenario. "name" is the name of the scanned card key; "mac" is the name mac address of the scanned card key. In particular, if both the mobile device and the card key are BLE (bluetooth low energy technology), the data packet further includes RSSI (signal strength indicator value) broadcast data of the card key. When the data packet is generated, if the number of bits of the values of the app id and the name is insufficient, 0 is complemented; if the number of bits of the value is too long, the bytes with the corresponding length are intercepted as the value in the data packet.
For the above step 303, the computer may be pre-installed with an application program a (APP a), and the application program a executes the program control related to the computer in this embodiment. When executing step 303, the application a may start an information monitoring function of the computer, and monitor information sent by the mobile device. If the first information sent by the mobile equipment is monitored, a connection request is generated according to the first information so as to request the mobile equipment to be connected to the card key.
It can be understood that, further, if more than two card keys are displayed in the first information to be accessible, the application program a selects the card key with the largest signal strength as the connection target according to the signal strength indication value in the first information. Then, the name of the connection target is written into the generated connection request.
In particular, the packet format of the connection request may be as follows:
| length (byte) | 4 | 4 | package length-4-4 | 16 |
| Value of | packagelength | command | data | CRC |
In the packet format of the connection request shown in the table above, "packagelength" is the length of the packet, and "command" indicates the instruction type of the connection request, including connect, disconnect, send apdu, or other custom instructions. Wherein, in particular, "CRC" is a CRC check code generated by the computer according to the first information for checking the validity of the connection request by the CRC check code when the mobile device receives the connection request.
For step 304 described above, the computer sends a connection request to the mobile device after generating the connection request. Typically, the computer is directly transmitted to the mobile device by wired or wireless means.
For step 305, the mobile device receives the connection request, and the application B establishes a transit communication link between the computer and the card key according to the connection request. It will be appreciated that, further, since the connection request includes the name of the connection target "card key", when the mobile device scans more than two card keys, when the transit communication link is established, the card key that needs to be connected may be determined according to the name of the card key in the connection request.
In particular, in an application scenario, in order to ensure the validity of the connection, the application program B may also check the CRC check code in the connection request, and if the check is successful, execute the operation of establishing the transit communication link; otherwise, if the verification fails, the connection request may be discarded.
For the step 305, the mobile device establishing the transit communication link may specifically include: in one aspect, application B establishes a first communication link with application a of the computer using SSL protocol; on the other hand, the application B establishes a second communication link with the card key using the link encryption scheme in the bluetooth specification. And then constructing a corresponding relation between the first communication link and the second communication link, so as to form a communication link of the application program A < - > and the application program B < - > card key.
Particularly, if the mobile device is further provided with an NFC interface, a second communication link of near field communication with the card key can be established through the NFC interface; if the mobile device is further provided with a wifi interface, a second communication link based on wifi connection between the mobile device and the card key can be established through the wifi interface. It will be appreciated that other wireless connection methods may be used between the mobile device and the card key in this embodiment, which is not limited in particular.
After the transit communication link is established in step 305, the communication process between the computer and the card key in this embodiment, as shown in fig. 4, may include:
401. the computer sends a processing request to the mobile device;
402. after receiving the processing request, the mobile equipment acquires a processing instruction in the processing request;
403. the mobile equipment sends an execution request to the card key according to the processing instruction;
404. the card key receives the execution request and performs corresponding processing, and feeds back processing result information to the mobile equipment;
405. the mobile device returns the processing result information to the computer.
For the step 402, after receiving the processing request, the mobile device may further obtain a CRC check code in the processing request, check the CRC check code, discard the processing request if the check fails, and obtain a processing instruction in the processing request if the check succeeds, and execute the subsequent steps.
In this embodiment, in order to enable the card key to be conveniently accessed to the computer for transfer communication through the mobile device, the card key can be used on the PC without a card reader, so that the use restriction of the card key on the PC is removed, and the advantage of portability is expanded to all use scenes.
