The session key negotiation process between the credential card reading device 20 and the first credential card security control device 40 can be referred to the description of embodiment 3, and will not be described in detail here.
In an optional implementation of the embodiment of the present invention, one server 30 may be connected to a plurality of credential card security control devices, and therefore, in this optional implementation, the server 30 is further configured to select the first credential card security control device 40 from the plurality of credential card security control devices before sending the card seeking request to the first credential card security control device 40.
In an alternative implementation of the embodiment of the present invention, the manner in which the server 30 selects the credential card security control device includes, but is not limited to, one of the following:
(1) selecting the certificate card safety control equipment corresponding to the certificate card reading device 20 from a pre-stored corresponding relationship, wherein one or more certificate card reading devices corresponding to each certificate card safety control equipment in a plurality of certificate card safety control equipment are recorded in the corresponding relationship;
for example, the server 30 is connected to a plurality of credential card security control devices, and can store the correspondence of each of the plurality of credential card security control devices with a plurality of credential card reading apparatuses. The correspondence may also be set according to a certain rule, for example, the correspondence may be divided according to a geographical area, and a plurality of credential card reading devices in the same area correspond to the same credential card security control device, or each credential card reading device may be assigned an ID and divided according to an ID number, and credential card reading devices having IDs in the same range correspond to the same credential card security control device, or may be divided according to addresses (for example, IP addresses) of the credential card reading devices in a network. With this alternative embodiment, a plurality of credential card reading devices can be mapped to one credential card security control device through the server 30, which improves the utilization rate and system manageability of the credential card security control device, and a failure can be quickly located if it occurs by mapping a plurality of credential card reading devices to one credential card security control device.
For example, in a banking system, a plurality of certificate card security control devices may be set at a business location, a correspondence may be set in a server, the front-end certificate card reading devices may be numbered, and then the certificate card security control devices corresponding to each certificate card reading device may be recorded in the correspondence. For the situation that a plurality of business places share a plurality of certificate card safety control devices, the server can set a corresponding relation to record that the certificate card reading device from each business place corresponds to the certificate card safety control device, or can carry out the distribution of the certificate card safety control device according to the IP address of the certificate card reading device at the front end.
(2) And selecting the certificate card safety control equipment with the current working state being idle from the plurality of certificate card safety control equipment as the first certificate card safety control equipment.
For example, the server 30 may record the operating state of each of the multiple credential card security control devices in the system, and when receiving a card searching request from the credential card reading apparatus 20, the server 30 may select, according to the operating state of each credential card security control device, a credential card security control device whose current operating state is idle as a credential card security control device corresponding to the credential card reading apparatus, and mark the operating state of the selected credential card security control device as non-idle. Through the optional implementation scheme, the situation that one certificate card safety control device receives information of a plurality of terminals at the same time to cause reduction of processing efficiency can be avoided.
In an optional implementation of the embodiment of the present invention, in order to quickly release the unused credential card security control device, the server 30 may further mark the operating state of the selected credential card security control device as idle after the credential card reading device finishes communicating with the selected credential card security control device. Of course, in the specific implementation process, if all the credential card security control devices are in the non-idle state, the credential card security control devices can be selected according to the load states of the credential card security control devices to achieve load balancing.
For example, in a banking system, a plurality of credential card security control devices may be installed at one or more business locations or the whole network, an idle credential card security control device pool may be installed in the server, the server may take out one credential card security control device from the idle credential card security control device pool when receiving a request sent from a front-end credential card reader, allocate the credential card security control device to a current credential card reader, process a request related to the current credential card reader by the credential card security control device, remove the credential card security control device from the idle credential card security control device pool, and place the credential card security control device in the idle credential card security control device pool after use.
Through the optional embodiment, the server can select a proper certificate card security control device for the certificate card reading device 20 according to specific applications, so that the utilization rate of the certificate card security control device can be improved, and meanwhile, the data processing efficiency can be improved.

In addition, the identification card information may be stored in the storage device 50 in a plaintext form or may be stored in the storage device 50 in an encrypted form, and the embodiment is not limited to this.
In another optional implementation of the embodiment of the present invention, after the terminal 10 receives the credential card information, if the terminal 10 has a display module, the received credential card information may be displayed through the display module, and if the terminal 10 does not have the display module, the terminal 10 may transmit the credential card information to an external display device for storage. Thus, in this alternative embodiment, the terminal 10 is also used to send credential card information to the display device 60; and the display device 60 is used for displaying the certificate card information. Through the optional implementation mode, the read certificate card information can be displayed, so that a user can know the certificate card information stored in the certificate card.

Example 3
This embodiment provides a method for acquiring information of a certificate card, which can be implemented by the system or apparatus provided in embodiments 1 to 2.
Fig. 3 is a schematic flowchart of a method for acquiring information of a credential card according to this embodiment, and as shown in fig. 3, the method mainly includes the following steps S301 to S320.
Step S301, the terminal sends an operation request to the certificate card reading device.
In the specific implementation process, the terminal and the certificate card reading device can be connected through a wired connection (for example, a USB interface, a serial port, an audio interface, and the like) or a wireless connection (for example, WIFI, bluetooth, infrared, NFC, and the like).
In this embodiment, when the user needs to read the credential card information stored in the credential card, the user sends an operation request to the credential card reading device through the terminal to indicate that the credential card reading device needs to read the credential card information stored in the credential card. For example, a user can input an operation instruction to the terminal through a certain key in the terminal, and the terminal responds to the operation instruction input by the user and sends an operation request to the certificate card reading device.
In addition, the certificate card information stored in the certificate card is stored in an encrypted manner, and due to the particularity of the certificate card, only the certificate card safety control equipment can decrypt the certificate card information stored in the certificate card. In a specific implementation process, the content that needs to be decrypted by the first credential card security control device may be set in the card reading request, for example, the first credential card security control device may be set to only read basic information (e.g., name, gender, birth year and month, etc.) stored in the credential card, the first credential card security control device may also be set to read basic information + photograph + fingerprint information, etc. stored in the credential card, and the setting may be specifically performed as needed. In a specific implementation process, the setting can be performed by a user at a terminal, after the setting is completed, the setting is sent to the certificate card reading device through an operation request, and the certificate card reading device sends the setting information to the first certificate card safety control device according to the setting of the user in a card reading process.
Step S302, the certificate card reading device receives the operation request and broadcasts the card searching command periodically.
In a specific implementation process, the identification card reading device can periodically broadcast a card searching instruction through a Radio Frequency (RF) antenna of the identification card reading device, and if the identification card exists in a readable range of the identification card reading device, the identification card can receive the card searching instruction and respond to the card searching instruction.
Step S303, the credential card reading device receives a response message returned by the credential card, and determines that the response message is the card-searching confirmation data for the card-searching instruction.
In this embodiment, the credential card reading device sends a card-searching command to the outside at intervals of time through its RF module, and after receiving the card-searching command, the credential card returns a response message carrying card-searching confirmation data to the credential card reading device, and after determining that the card-searching confirmation data sent by the credential card is received, the credential card reading device executes step S304.
And step S304, the certificate card reading device stops broadcasting the card searching command and sends a card searching request to the server.
In this embodiment, the card search request may carry card search request data, so that the credential card security control device can know the type of the received card search request.
In this embodiment, the servers may be distributed, centralized, or virtual servers, and the embodiment is not limited to this. In addition, the server and the first certificate card security control device may be connected through a wired connection or a wireless connection, and this embodiment is not limited in this embodiment.
Step S305, the server receives the card searching request and sends the card searching request to the first certificate card safety control equipment.
In a specific application, the credential card security control device connected to the server may be one (i.e., the first credential card security control device) or multiple, and in the case of multiple credential card security control devices, the server selects one credential card security control device (i.e., the first credential card security control device) for the credential card reading apparatus before sending the card searching request.
In an alternative implementation of the embodiment of the present invention, the manner in which the server selects the credential card security control device includes, but is not limited to, one of the following:
(1) selecting certificate card safety control equipment corresponding to the certificate card reading device from a pre-stored corresponding relationship, wherein one or more certificate card reading devices corresponding to each certificate card safety control equipment in a plurality of certificate card safety control equipment are recorded in the corresponding relationship;
for example, the server is connected to a plurality of credential card security control devices, and can store a correspondence relationship of each of the plurality of credential card security control devices to a plurality of credential card reading apparatuses. The correspondence may also be set according to a certain rule, for example, the correspondence may be divided according to a geographical area, and a plurality of credential card reading devices in the same area correspond to the same credential card security control device, or each credential card reading device may be assigned an ID and divided according to an ID number, and credential card reading devices having IDs in the same range correspond to the same credential card security control device, or may be divided according to addresses (for example, IP addresses) of the credential card reading devices in a network. Through this optional implementation scheme, can be through the server, with a plurality of certificate card reading device to a certificate card safety control equipment, improved certificate card safety control equipment's utilization ratio and system manageability to, through with a plurality of certificate card reading device to a certificate card safety control equipment, also can fix a position the trouble rapidly if breaking down.
For example, in a banking system, a plurality of certificate card security control devices may be set at a business location, a correspondence may be set in a server, the front-end certificate card reading devices may be numbered, and then the certificate card security control devices corresponding to each certificate card reading device may be recorded in the correspondence. For the situation that a plurality of business places share a plurality of certificate card safety control devices, the server can set a corresponding relation to record that the certificate card reading device from each business place corresponds to the certificate card safety control device, or can carry out the distribution of the certificate card safety control device according to the IP address of the certificate card reading device at the front end.
(2) And selecting the certificate card safety control equipment with the current working state being idle from the plurality of certificate card safety control equipment as the first certificate card safety control equipment.
For example, the server may record the working state of each of the multiple credential card security control devices in the system, and when receiving a card search request from the credential card reading apparatus, the server may select, according to the working state of each credential card security control device, a credential card security control device whose current working state is idle as a credential card security control device (i.e., a first credential card security control device) corresponding to the credential card reading apparatus, and mark the working state of the selected credential card security control device as non-idle. Through the optional implementation scheme, the situation that one certificate card safety control device receives information of a plurality of terminals at the same time to cause reduction of processing efficiency can be avoided.
In an optional implementation of the embodiment of the present invention, in order to quickly release the unused credential card security control device, the server may further mark the operating state of the selected credential card security control device as idle after the credential card reading device finishes communication with the selected credential card security control device. Of course, in the specific implementation process, if all the credential card security control devices are in the non-idle state, the credential card security control devices can be selected according to the load states of the credential card security control devices to achieve load balancing.
For example, in a banking system, a plurality of certificate card security control devices may be installed at one or more business locations or the whole network, an idle certificate card security control device pool is installed in a server, the server, upon receiving a card-seeking request from a front certificate card reading device, takes out one certificate card security control device from the idle certificate card security control device pool, allocates the certificate card security control device to a current certificate card reading device, processes a request related to the current certificate card reading device by the certificate card security control device, and moves out the certificate card security control device from the idle certificate card security control device pool, and after the certificate card security control device is used up, puts the certificate card security control device into the idle certificate card security control device pool.

Step b 8: the certificate card reading device sends a first data packet to the first certificate card safety control device, wherein the first data packet comprises: a first ciphertext E1 and a first signature value S1;
in this embodiment, the credential card reading device has a networking function, and can directly send the first data packet to the first credential card security control device through the wired network or the wireless network.
