Description

App calling method and mobile device

technical field

The invention relates to a method for calling a program, in particular to a method for calling a Java program (Applet) applied to the framework of a Java Card virtual machine.

Background technique

As the applications on mobile terminal devices become more diverse and the complexity of business links increases, the services of mobile terminals are also becoming more and more diverse.

Previous personal service authentication and identification terminals, such as Subscriber Identity Module (Subscriber Identity Module, SIM) card, identity identification (ID) card, bank card, etc., are all a Java card and Java SIM architecture and a single input and output port (I /O) interface Java COS smart card, and these smart cards are passive components, which are called by the mobile terminal through the protocol, therefore, if the application Java programs of these cards are to be operated on the Java Card virtual machine in the same card The Java program (Applet) on the computer must implement SIO (Shareable Interface Object) in the Java Applet. That is to say, the current Java Applet calls are all executed by calling instructions from mobile terminals or external card reading devices. To execute JavaApplet Calls between Java Applet and Java Applet must change the relevant specifications of the current Java Applet. However, the current Java Card and Java SIM architectures have been in operation for many years, and more than 100 million related smart cards have been issued to the market. It is impossible to change the specifications, and the practice of the SIO interface will also have security concerns. In addition, the bank card and other security application specifications published by many international organizations do not include these SIO design call specifications, let alone calls between JavaApplets.

Therefore, under the premise of not changing the current Java Applet specification, how to execute the call between Java Applet and Java Applet is the focus of the invention in this case.

Contents of the invention

The purpose of the present invention is to provide a program call method that can execute communication calls between Java Applets.

The program calling method of the present invention is executed in a control module, and the control module stores several Java programs (Applets), and the program calling method comprises the following steps:

(A) receiving a signal transmitted by an input module;

(B) According to the received signal, confirm the state of the actual channel and the virtual channel corresponding to each Java program, and carry out the flag setting of the virtual channel;

(C) judging whether the received signal contains a multi-channel management command, if so, then perform channel setting according to the multi-channel management command, and execute step (D); if not, then execute step (F);

(D) judging whether the virtual channel that is set to be opened is still open, if so, then perform step (E); if not, then perform step (A);

(E) receiving the signal output by the Java program corresponding to the virtual channel set to open, and returning to the execution step (B); and

(F) Execute the corresponding processing program according to the type of the signal transmitted by the input module. In this way, by returning the communication signal between Java programs to the calling Java program, the Java program can replace the input module and send relevant information to the called Java program, thereby achieving the function of mutual communication between Java Applets .

Preferably, the above step (D) is based on whether the Java program corresponding to the virtual channel that is set to be opened is called by other Java programs, or whether the command output by the Java program corresponding to the virtual channel that is set to be opened is It is determined whether the virtual channel that is set to be opened is still open by returning commands related to the virtual channel and its Java program. Of course, the virtual channel can also be closed by calling the Java program that opens the virtual channel and calling the channel command again to close the virtual channel.

In detail, the step (D) is to determine whether the virtual channel is called by other Java programs according to whether the flag (Flag) included in the signal output by the Java program corresponding to the opened virtual channel is marked as being in use.

In addition, step (F) includes the following sub-steps:

(F-1) Judging whether the signal sent by the input module is an authentication command, if so, then controlling the Java program to communicate with the Java program corresponding to the authentication command to transmit information; if not, then execute step (F- 2);

(F-2) Determine whether the signal transmitted by the input module is a standard Java Applet command, if so, then execute according to the standard Java Applet command, if you need to call other Java programs, you can call other corresponding Java programs through the special virtual channel command format; If not, proceed to step (F-3); and

(F-3) Return the signal to the input module.

Moreover, this program call method also includes a step (G) before the step (A), the input module sends a reset command to the control module, so that the control module will be reset before each system reset or power on. reset.

Step (B) is to confirm the use status of each virtual channel according to whether a flag corresponding to each virtual channel is registered.

In step (C), if the received signal contains a multi-channel management command, the channel is set according to the multi-channel management command, the associated channel is set to be executed, and the corresponding virtual channel is set during the channel opening period. A flag of is marked as occupied.

In addition, another object of the present invention is to provide a mobile device capable of executing the above program calling method.

The mobile device of the present invention includes an input module and a control module. Wherein, the control module includes an input-output port electrically connected to the input module, a program storage area storing several Java programs, and a control unit electrically connected to the input-output port and the program storage area.

The control unit receives the signal sent by the input module, and according to the received signal, confirms the status of a virtual channel corresponding to each Java program. The Java program can call an unoccupied channel by itself and define it as a status of a virtual channel. The virtual channel calls other Java programs in the card. If the signal received by the system includes a multi-channel management command, the channel setting is performed according to the multi-channel management command, and it is judged whether the opened virtual channel is still open. If so, Then receive the signal output by the Java program corresponding to the virtual channel opened by the setting and execute the system program repeatedly without returning to the input module; if the received signal does not include such virtual channel, the process of calling the Java program is associated with this virtual channel The multi-channel management command executes the corresponding processing program according to the type of the signal transmitted by the input module. This can also achieve the effect of mutual communication between various Java Applets.

Preferably, the input module is a baseband module.

Preferably, the control unit is based on whether the Java program corresponding to the virtual channel that is set to be opened is called by other Java programs, or whether the command output by the Java program corresponding to the virtual channel that is set to be opened belongs to the virtual channel Determine whether the virtual channel that is set to be opened is still open by returning an instruction related to the Java program. Of course, the virtual channel can also be closed by calling the Java program that opens the virtual channel and calling the channel command again to close the virtual channel.

Specifically, the control unit judges whether to call other Java programs according to whether the flag contained in the signal output by the Java program corresponding to the opened virtual channel is marked as being in use.

In addition, the control unit judges whether the Java program corresponding to the virtual channel that is set to be opened is called by other Java programs or whether the command output by the Java program corresponding to the virtual channel that is set to be opened belongs to the virtual channel and is related to its Java program. Return command, if yes, receive the signal output by the Java program and set the flag of the virtual channel.

In addition, if the signal transmitted by the input module does not contain a multi-channel management command, the control unit judges whether the signal transmitted by the input module is an authentication command, and if so, controls the Java program to communicate with the Java program corresponding to the authentication command. To transmit information, if not, then the control unit judges whether the signal transmitted by the input module is a standard Java Applet command, if so, then execute according to the standard Java Applet command, if it is necessary to call other Java Applet programs, it can go through the special virtual channel command format Call other corresponding Java programs, otherwise return the signal to the input module.

If the control unit judges that the received signal contains a multi-channel management command, it will set the channel according to the multi-channel management command, set the execution of its associated channel to open, and set the period corresponding to the virtual channel during the channel opening period. A flag (Flag) indicates that it is occupied.

In addition, the control unit confirms the status of each virtual channel according to whether a flag corresponding to each virtual channel is registered.

The beneficial effect of the present invention lies in that the mutual communication between Java Applets can be executed without changing the standard of the current Java Applets through the calling method of the program.

detailed description

The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

Referring to Fig. 1, it is a preferred embodiment of the mobile device 100 of the present invention, the mobile device 100 can be a mobile phone or a personal digital assistant (Personal Digital Assistant, PDA), etc. Devices for network communication.

In this embodiment, the mobile device 100 includes an input module 10 and a control module 20 .

The input module 10 is a base band module (base band), or includes various input devices related to ISO7816/UART, which is not limited to this embodiment.

The control module 20 is an integrated circuit application chip (Chip) based on Java card design, and includes an input and output port (I/O port) 21 electrically connected to the input module 10, a program storage area 22 and an electrically connected input and output port. The control unit 23 of the port 21 and the program storage area 22 . The input and output port 21 communicates with the input module 10 through the ISO-7816 protocol to transmit information each other; the program storage area 22 provides several Java programs (Java Applets) to store, and these Java Applets can be connected from the air (Over The Air, OTA) download, it can be user identification application development tool (SIM Application Toolkit, STK) program or bank Java Applet etc.; The port 21 is electrically connected to the program storage area 22 for mutual transmission of information between the input module 10 and the program storage area 22 , and controls multiple Java Applets in the program storage area 22 to communicate with each other.

In the present invention, the control module 20 is built on the Java Card virtual machine architecture, which can make other applications in the mobile device 100 that also comply with the Java Card standard specification, such as: EMV, PBOC, and Certificate Authority (Certificate Authority, CA) , public key infrastructure (Public Key Infrastructure, PKI), etc., can be transplanted to the Java virtual machine of the control module 20 to execute, and because the virtual machine architecture of the Java card is a framework that can support the Global Platform (Global Platform), it has The ability to update can update the Java Applet, security authentication components and systems in the program storage area 22 in the control module 20, which is a security circuit element (Security Element). In particular, the control module 20 can be fabricated in the input module 10 and integrated with the input module 10 into the same chip, or can be independently formed into a single chip, and the manufacturing method is not limited.

Referring to FIG. 1 and FIG. 2 , since the control module 20 is an integrated circuit application chip designed based on Java Card, the control module 20 of each mobile device 100 needs to be initialized in the industrial chain before leaving the factory. As in step S11, relevant personnel in the factory can use a card reader or an initialization device to judge whether the control module 20 is in an initial state (NativeStatus). If the control module 20 is in an initial state, it means that the control module 20 is an initial card (Native Card). Step S12 will be executed to initialize the control module 20 , and load the operating system, card management program and other software, as well as relevant user personalization data into the control module 20 . If the control module 20 is not in the initial state, it means that the control module 20 is already in the Java Card state (or in the Java Card state), then the control module 20 does not need to be initialized, and the process ends.

Next, referring to FIG. 1 and FIG. 3 , the detailed process executed by the control module 20 will be described in detail below.

Step S10 , after the user turns on the mobile device 100 or actively resets it, the input module 10 sends a reset command to the control module 20 when the control unit 23 needs to be reset.

Step S20 , the control unit 23 receives the signal transmitted by the input module 10 through the input and output port 21 .

In step S30, the control unit 23 confirms the status of the actual channel and the virtual channel (Virtual Channel) corresponding to each Java Applet in the program storage area 22 according to the received signal. In this embodiment, each actual channel and virtual channel has a corresponding flag (Flag), and the control unit 23 confirms the use status of each actual channel and virtual channel according to whether the flags are registered or not. In addition, if the signal contains a channel setting command, such as: a new channel (Create Channel) command, a close channel (Close Channel) command, etc., then the control unit 23 sets the corresponding actual channel or channel according to the channel setting command. Virtual channels, for example: set the current Java program (Current Applet) to execute in one of the virtual channels. If there is no channel setting command in the signal, step S40 is directly executed after confirming the status of each actual channel and virtual channel.

Step S40, the control unit 23 judges whether the received signal includes a multi-channel (Multi-Channel) management command, the multi-channel management command includes several channel settings, and each channel setting will correspond to the program storage area 22 The specified Java Applet. If the signal received by the control unit 23 includes a multi-channel management instruction, execute step S50; if not, execute step S80.

In step S50, the control unit 23 sets each channel according to the multi-channel management command, for example: setting a specific channel to be ON (ON), and turning off the rest of the channels (OFF), and storing the messages in the channels that are closed during execution. into the temporary storage area of the memory, or set multiple virtual channels to open at the same time. In this embodiment, the control unit 23 opens the virtual channel previously set according to the channel setting command, so that the JavaApplet (i.e. Current Applet) corresponding to the virtual channel can communicate with other Java Applets or input modules 10, and end Then step S60 is executed.

In step S60, the control unit 23 determines whether the virtual channel set to be enabled is still enabled. In this embodiment, the control unit 23 is based on whether the Java program (Applet) corresponding to the virtual channel that is set to be opened is called by other Java programs (Applet), or returns an instruction to the input module 10 (that is, it is set to Determine whether the virtual channel corresponding to the Java program output) belongs to the virtual channel and its Java program-related return instructions to determine whether the virtual channel is still open. In more detail, the control unit 23 is based on the opened virtual channel. Whether the flag contained in the signal output by the corresponding Current Applet is marked in use, if yes, then execute step S70, the control unit 23 receives the signal output by the Current Applet corresponding to the virtual channel that is set to open, and Step S30 is executed after receiving. If the control unit 23 judges that the signal output by the Current Applet is not in the virtual channel setting, step S20 is executed. In particular, the virtual channel can also be closed by calling the Java program that opens the virtual channel and calling the channel command again to close the virtual channel.

In step S80, the control unit 23 switches to a corresponding processing program according to the type of the signal it receives. In this embodiment, step S80 may include the following steps:

Step S81, the control unit 23 judges whether the received signal is an authentication command (for example: SIM/USIM Applet), if so, it means that the signal is a Global System for Mobile Communications (Global System for Mobile Communications, GSM) command, then Execute step S82; otherwise, execute step S83.

In step S82, the control unit 23 controls the Current Applet to communicate with the Java Applet corresponding to the authentication command in the program storage area 22 to transmit information.

In step S83, the control unit 23 judges whether the received signal is a standard Java Applet command or a Java SIM Applet command, and if so, executes step S84. If the signal received by the control unit 23 is neither a GSM command nor a standard Java Applet command or a Java SIM Applet command, then it is determined to be a Java Card Runtime Environment (JCRE) command or a test command, and the control unit 23 will execute step S85.

Step S84, the control unit 23 calls other corresponding Java Applets in the program storage area 22 through the special virtual channel command format according to the standard Java Applet command or the Java SIM Applet command, so that the Current Applet can communicate with the called Java Applet to transmit information, and return to step S60 after calling.

In step S85 , the control unit 23 returns the signal to the input module 10 through the I/O port 21 . In particular, all signals to be transmitted to the input module 10 will pass through the judgment of step S60 to confirm whether the signals are communication information between Java Applets or communication information between Java Applets and the input module 10 . Of course, with different settings, the control unit 23 can also submit the signal to a specific JCRE circuit for execution, or call a specific program through a specific Java Applet command to call its specific service command and signal flow, which is not based on this embodiment. limit.

Therefore, it can be seen from the above steps S10 to S80 that the mobile device 100 implements a multi-channel call security authentication element to conform to the architecture of the Java virtual machine. During the entire operation process, the channel management mechanism is completely controlled by the control unit 23 The multi-channel management command in the signal is being managed, and the switching communication mode in step S80 also all follows the framework of the Java Card virtual machine, according to the Application Programming Interface (Application Programming Interface, API) or object (Object) in each virtual channel Wait to call the instruction library (Library) and memory (Memory) in the corresponding initial layer (Native layer). In addition, when the Java Applet calls the application programming interface (API), it will first call the Create Channel command to set the corresponding virtual channel, and then call the Close Channel command to release the occupied channel. Virtual channel, so as to ensure the normal operation of the input module 10 service order.

In addition, this Java Applet calling method can not only be applied to the mobile device 100 with a single input and output port, but also can achieve mutual communication between Java Applets through this Java Applet calling method for the Java Card virtual machine framework with multiple input and output ports, so It is not limited to this embodiment.

In summary, the mobile device 100 of the present invention uses the control module 20 as the virtual machine architecture of the Java card, and adds an Open Channel (Open Channel) for setting the virtual channel in the application program interface (API) of the control unit 23. ) command, close channel (Close Channel) command, and allow the application programs of each Java Applet to call and return related service commands to the Java Applet (Send-Out Going Data to Virtual Channel) on the virtual channel, so as to achieve each Java Applet Communicate with each other to transmit information, so the purpose of the present invention can indeed be achieved.
