It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
Referring to fig. 1, a schematic block diagram of an application scenario of a chip system loading method according to an embodiment of the present application is shown. The chip system loading method provided by the embodiment can be applied to install a chip card 100, where the chip card 100 includes a bluetooth main control chip 110, a near field communication chip 120 electrically connected to the bluetooth main control chip 110, and a plurality of security chips 130 electrically connected to the bluetooth main control chip 110.
In this embodiment, the chip card 100 can be in data communication with an external terminal device, such as the first terminal device 200 or the second terminal device shown in fig. 1. The first terminal device 200 may be a mobile terminal or a dedicated read-write device on which the chip card 100 is installed, and the mobile terminal may provide a hardware operating environment for the chip card 100. For example, the mobile terminal may be a smart phone, a tablet computer with a card insertion function, and the like. The second terminal device may be a tool for loading the chip card 100, by means of which the chip system COS of the respective security chip 130 in the chip card 100 can be loaded or updated.
In this embodiment, the bluetooth main control chip 110 may be a micro control Unit integrated with a bluetooth communication module, and the micro control Unit appropriately reduces the frequency and specification of a Central Processing Unit (CPU), and integrates peripheral interfaces such as a Memory, a counter (Timer), a USB, an a/D conversion, a UART, a PLC, a DMA, and even an LCD driving circuit on a single chip, thereby forming a chip-level computer and performing different combination control for different applications. The bluetooth communication module is used for realizing data interaction between the micro-processing unit and the terminal device 300 or an external payment terminal and the like.
In this embodiment, the near field communication chip 120 combines the near field communication technology and the mobile communication technology, so as to realize multiple functions of electronic payment, identity authentication, ticketing, data exchange, anti-counterfeiting, advertisement, and the like, and the near field communication chip 120 can exchange data through an active mode and a passive mode.
In this embodiment, each security chip 130 may be installed with various large-scale industry applications of corresponding application types, for example, an operator factory application, a life application (for example, a bus card application, a subway card application, and a social security card application), and a mobile payment application (for example, a payment treasure application, and a unionpay application), and thus, the security chip 130 may realize integration of multi-industry services, integrate multiple industry applications into the security chip 130, and enable a user to not carry multiple industry cards, thereby improving user experience, greatly facilitating life of people, and ensuring security of a payment environment.
The chip system cos (chip Operating system) in each secure chip 130 is the core of the chip card 100, and mainly controls the chip card 100 to exchange data with the outside world and complete the processing of various commands in the card. Each secure chip 130 is generally provided in the form of a chip, and is equipped with a chip system COS to implement functions such as data secure storage, encryption and decryption operations, and the like. In the prior art, after the chip card 100 is selected, a corresponding tool is selected according to the chip card 100 to load the COS, for example, the COS of the chip card 100 commonly used in the market is loaded in a contact manner by adopting the international standard ISO/IEC7816 protocol. Therefore, because the security chip 130 generally only supports the loading of the COS through the ISO/IEC7816 contact protocol, but due to the problem of updating the channel management authority of the mobile terminal in which the chip card 100 is installed, when the COS of the security chip 130 needs to be updated or loaded, a user often needs to return the chip card 100 to a related card issuing organization for processing, which causes a lot of inconvenience and reduces user experience.
It should be noted that the above prior art solutions have shortcomings, which are the results of practical and careful study by the inventor, and therefore, the discovery process of the above problems and the solutions proposed by the following embodiments of the present application for the above problems should be the contribution of the inventor to the present application in the process of the present application.
In view of the above problems, the inventor of the present application proposes the following technical solution, which supports the implementation of loading and updating the chip system of the security chip 130 through a non-contact mode, has stronger applicability in an actual scene, and solves the problem of inconvenience caused by the fact that a user often needs to return the chip card 100 to a related card issuing mechanism for processing in the prior art, thereby enhancing user experience.
Specifically, please refer to fig. 2, which is a flowchart illustrating a loading method of a chip system according to an embodiment of the present application, where the loading method of the chip system is executed by the chip card 100 shown in fig. 1. It should be noted that the loading method of the chip system provided in this embodiment is not limited by fig. 2 and the following specific sequence, and the detailed flow of the loading method of the chip system is as follows:
in step S110, when each secure chip 130 receives a chip system loading request, it is determined whether the chip system of the secure chip 130 can be loaded currently.
In this embodiment, each secure chip 130 may be loaded with a corresponding Bootloader program, and the Bootloader program may download and update the chip system of each secure chip 130 through the SPI interface. As an embodiment, when the chip card 100 is powered on, each secure chip 130 first executes the Bootloader program, and can detect whether a chip system identifier exists currently through the Bootloader program, and if so, determine that a chip system of the secure chip 130 can be loaded currently; if not, the system-on-chip of the security chip 130 cannot be loaded currently is determined.
Whether the chip system identifier exists can be used for representing whether the chip system COS of the security chip 130 can normally enter, if the chip system identifier exists, the chip system COS of the security chip 130 can be identified to normally enter, otherwise, the chip system COS cannot normally enter, and the chip system COS of the security chip 130 is not installed or needs to be updated.
Step S120, if it is determined that the chip system of the security chip 130 cannot be loaded currently, detecting a current working mode of the chip card 100.
In this embodiment, if it is determined that the chip system COS of the security chip 130 cannot be loaded currently, the chip system COS of the security chip 130 needs to be initialized, and in the initialization process, in this step, first, the current working mode of the chip card 100 needs to be detected, where the working mode includes a contact mode and a non-contact mode.
As an embodiment, the mode for detecting the current working mode of the chip card 100 can comprise the following steps:
detecting whether the bluetooth master control chip 110 is currently in bluetooth communication with the first terminal device 200, whether the near field communication chip 120 is currently in a communication magnetic field of the first terminal device 200 and/or whether the chip card 100 is currently performing a preset contact protocol operation, if detecting that the chip card 100 is currently performing the preset contact protocol operation, determining that the chip card 100 is currently in a contact mode, and if detecting that the bluetooth master control chip 110 is currently in bluetooth communication with the first terminal device 200 and/or whether the near field communication chip 120 is currently in the communication magnetic field of the first terminal device 200, determining that the chip card 100 is currently in a non-contact mode.
The detecting of whether the bluetooth master control chip 110 is currently in bluetooth communication with the first terminal device 200 is used to detect whether the chip card 100 is currently in bluetooth communication with the first terminal device 200, and if the bluetooth communication is present, it is determined that the chip card 100 is currently in a non-contact mode. Detecting whether the NFC chip 120 is currently located in the communication magnetic field of the first terminal device 200 is used to detect whether the chip card 100 has NFC communication with the first terminal device 200, and if so, determining that the chip card 100 is currently located in a contactless mode. Detecting whether the chip card 100 is performing a preset contact protocol operation is used for detecting whether the chip card 100 has a preset contact protocol communication, such as an ISO/IEC7816 protocol communication, in the second terminal device, and if so, determining that the chip card 100 is currently in a contact mode.
It can be seen from the above steps that a user can select not only a preset contact protocol to communicate the chip card 100 with a second terminal device (e.g., a tool) but also a non-contact manner to communicate with the first terminal device 200, for example, as shown in fig. 1, when a terminal bluetooth chip 210 exists in the first terminal device 200, the non-contact communication between the chip card 100 and the first terminal device 200 can be realized through a bluetooth connection manner, and when a terminal NFC chip 220 exists in the first terminal device 200, the non-contact communication between the chip card 100 and the first terminal device 200 can be realized through an NFC connection manner. Of course, if the terminal bluetooth chip 210 and the terminal NFC chip 220 are both present in the first terminal device 200, the user may select which connection mode by himself, which is not particularly limited herein.
Step S130, when detecting that the chip card 100 is currently in the non-contact mode, receiving a selection response request sent by the first terminal device 200, and feeding back corresponding selection response information to the first terminal device 200 in response to the selection response request.
In this embodiment, if it is detected that the chip card 100 is currently in the non-contact mode, for example, when the chip card 100 implements non-contact communication with the terminal bluetooth chip 210 of the first terminal device 200 through the bluetooth master chip 110, at this time, the chip card 100 may send a bluetooth transmission channel establishment request to the terminal bluetooth chip 210 in the first terminal device 200 through the bluetooth master chip 110, so that the terminal bluetooth chip 210 establishes bluetooth communication with the bluetooth master chip 110 according to the bluetooth transmission channel establishment request. Then, the chip system update information sent by the first terminal device 200 through the terminal bluetooth chip 210 is received through the bluetooth master chip 110.
For another example, when the NFC chip 120 and the terminal NFC chip 220 of the first terminal device 200 implement contactless communication, at this time, the first terminal device 200 may send a request for Answer To request To reset (rats) To the NFC chip 120 of the chip card 100 through the terminal NFC chip 220. Then, the nfc chip 120 of the chip card 100 may receive a selective response request rats (request for Answer To reset) sent by the first terminal device 200, and feed back corresponding selective response information (Answer To Select, ATS) To the first terminal device 200 in response To the selective response request. Then, the first terminal device 200 establishes working communication with the nfc chip 120 of the chip card 100 according to the response information of the selection response, and sends chip system update information to the nfc chip 120.
At this time, the chip card 100 may establish a communication connection with the terminal bluetooth chip 210 through the bluetooth master control chip 110, and receive chip system update information sent by the first terminal device 200 through the terminal bluetooth chip 210; or, a communication connection is established with the terminal NFC chip 220 through the near field communication chip 120, and chip system update information sent by the first terminal device 200 through the terminal NFC chip 220 is received.
The selection response information (ATS) may be a series of strings that respond after the chip card 100 is reset by the first terminal device 200 and the chip card 100 is selected, and the strings provide information on how To perform subsequent work communication with the chip card 100 for the first terminal device 200.
It should be noted that, when the chip card 100 is installed in a mobile terminal, if the mobile terminal has an NFC module, in actual implementation, a communication connection may be established with the terminal NFC chip 220 through the NFC module of the mobile terminal, and after receiving chip system update information sent by the terminal NFC chip 220, the chip system update information is sent to the security chip, so that the security chip 130 of the chip card 100 may preferentially acquire the chip system update information through the NFC module of the mobile terminal.
In step S140, the near field communication chip 120 or the bluetooth master control chip 110 sends the received system-on-chip update information to the security chip 130.
In step S150, the security chip 130 updates the system-on-chip based on the system-on-chip update information.
In this embodiment, after the chip card 100 sends the received chip system update information to the security chip 130 through the near field communication chip 120 or the bluetooth master control chip 110, the security chip 130 may update the chip system based on the chip system update information. Thus, the initialization of the chip system of the security chip 130 is completed, and the updated chip system can directly load and execute the subsequent functions, such as managing the industrial applications in the chip card 100 and completing the processing of various commands in the chip card 100.
Based on the above design, the present embodiment supports the loading and updating of the chip system of the security chip 130 in a non-contact mode, has stronger applicability in an actual scene, and solves the problem of inconvenience caused by the fact that a user often needs to return the chip card 100 to a related card issuing mechanism for processing in the prior art, thereby enhancing the user experience.
Further, referring to fig. 3, after the step S110, the method may further include the steps of:
step S115, if it is determined that the chip system of the security chip 130 can be loaded currently, entering the chip system and performing data interaction with the external terminal that sends the chip system loading request.
In this embodiment, if the chip system of the security chip 130 can be loaded normally, an initialization process is not required at this time, and the security chip directly enters the chip system and performs data interaction with the external terminal that sends the chip system loading request.
Further, referring to fig. 4, after the step S120, the method may further include the steps of:
step S125, when detecting that the chip card 100 is currently in the contact mode, receiving a reset signal sent by the second terminal device, and feeding back corresponding reset response information to the second terminal device in response to the reset signal.
In this embodiment, the chip card 100 may further include communication interaction contacts electrically connected To a second terminal device, so as To implement contact-type communication with the second terminal device through the communication interaction contacts, and the second terminal device may first send a Reset signal To the chip card 100, so that when the chip card 100 is detected To be currently in the contact mode, the chip card receives the Reset signal sent by the second terminal device, and feeds back corresponding Reset response information (Answer To Reset, ATR) To the second terminal device in response To the Reset signal. Then, the second terminal device establishes working communication with the chip card 100 through the communication interaction contact of the chip card 100 according to the reset response information, and sends chip system update information to the security chip 130 through a preset communication protocol.
Alternatively, the preset communication protocol may be an ISO/IEC7816 contact protocol, or other protocols, and is not particularly limited herein.
The reset response information may be a series of character strings that the chip card 100 responds after being reset by the second terminal device, and the characters may provide information on how to perform subsequent work communication with the chip card 100 for the second terminal device.
In step S126, the security chip 130 updates the system-on-chip based on the system-on-chip update information.
Through the above steps, the loading method of the chip system provided by this embodiment supports both loading and updating the chip system of the secure chip 130 in a contact manner and loading and updating the chip system of the secure chip 130 in a non-contact manner.
Further, on the basis, when the system-on-chip of the security chip 130 can be loaded normally, that is, after it is detected that the updating of the system-on-chip is finished, the received task processing command can be processed based on the updated system-on-chip and a command processing result can be fed back, so that a cycle of waiting for receiving the command, processing the command and replying the command is entered.
In summary, the embodiment of the present application provides a chip system loading method and a chip card. And when the chip card is detected to be in a non-contact mode, the Bluetooth main control chip or the near field communication chip establishes working communication with the first terminal equipment, and receives chip system updating information sent by the first terminal equipment according to the selective response information, so that the chip system is updated based on the chip system updating information. Therefore, the application supports the loading and updating of the chip system of the security chip through a non-contact mode, has stronger applicability in an actual scene, solves the problem that in the prior art, a user often needs to return the chip card to a related card issuing mechanism for processing, and further enhances the user experience.
