Description

TOKEN WITH A CONTROLLER CONTROLLING DATA FLOW}

Some embodiments of the present invention relate to a token comprising a control unit for controlling the flow of data between a smart card and a storage medium (especially a removable disk). More specifically, the present invention relates to a token including a controller for recognizing both data of a smart card and data of a storage medium, and controlling a data flow so as to recognize data of the smart card first.

In general, a smart card is also called an IC card or a chip card. According to the ISO standard, a smart card is a card in which one or more ICs are inserted. Smart cards have a much larger memory capacity, higher functionality and stability than conventional magnetic cards. Smart cards were developed in France in 1970 and started to be used by financial institutions, and later in the United States.

As the security trend is becoming more and more popular, the penetration rate of these smart cards has gradually increased, and now they have more than one smart card per person. However, the use rate is very low because an individual reader is required to use it on a PC. As a result, smart cards with a USB interface have been released.

 Since the introduction of smart cards with a USB interface, attempts have been made to combine a typical USB device, a removable disk and a smart card, but only physical coupling is possible, and logical coupling is impossible. Therefore, even if a smart card such as a SIM card and a removable disk such as an MSD card are physically coupled to a single device (token), desired card recognition can be achieved only through a passive action such as a switch operation.

That is, when a token equipped with both a SIM card and an MSD card is connected to an external terminal such as a PC, the external terminal recognizes only one of these cards since a controller for controlling data flow is not separately provided in the token. Therefore, the user must select a card to be used through a switch operation, etc., which is inconvenient to use.

In addition, when using a conventional token, the external terminal can recognize only one of the SIM card and the MSD card, but not both of them at the same time, so that a program or an application that supports the expansion of the smart card function such as a widget can be applied to the MSD card. The problem arises that it is meaningless to mount. Therefore, the user may need to download an application for expanding and supporting the function of the smart card for each external terminal connected with the token, and a security problem may occur due to downloading an application application or the like to the external terminal.

In order to solve the problem or inconvenience caused when both the smart card and the storage medium are simultaneously recognized through an external terminal, the present invention automatically recognizes both the smart card and the storage medium, but automatically recognizes the data flow from the smart card first. By employing a data flow control unit to control the data, to disclose a token that can physically and logically combine the smart card and the storage medium.

A token is provided that includes a control for controlling the flow of data between a smart card and a storage medium (removable disk), as essentially shown or described with at least one of the figures, which will be described more fully in the claims.

Preferably, the token of the present invention comprises a smart card control unit for controlling the operation associated with the smart card; And a storage medium controller for controlling an operation related to the storage medium, wherein the smart card controller and the storage medium controller are connected to the data flow controller, respectively, to transmit / receive or record data.

The smart card controller is preferably connected to a data flow controller port of a number that precedes the storage medium controller.

The token of the present invention preferably further comprises a smart card socket connected with the smart card controller and mounted with the smart card, and a storage medium socket connected with the storage medium controller and mounted with the storage medium.

At least one of the smart card or the storage medium may be fixedly mounted on an internal substrate, wherein the storage medium is preferably a NAND flash memory.

Tokens according to another embodiment of the present invention, the data flow control unit for controlling the data flow so that the external terminal automatically recognizes both the smart card and the removable disk, the smart card before the removable disk; A smart card controller which controls an operation related to the smart card and is connected to the data flow controller to transmit / receive or record data; A removable disk controller which controls an operation related to the removable disk and is connected to the data flow controller to transmit or receive or record data; A smart card socket connected to the smart card controller and mounted with the smart card; A removable disk socket connected to the removable disk controller and mounted with the removable disk; And a wired communication unit configured to transmit and receive data from the external terminal and the data flow controller.

Advantageously, said smart card controller is coupled to a data flow controller port of a number that precedes said removable disk controller.

In this case, the smart card may be a SIM card, and the removable disk may be an SD card.

The communication unit preferably communicates via a USB interface.

Preferably, the token further comprises an RF wireless communication unit, when communicating through the RF wireless communication unit, the RF wireless communication unit transmits and receives data from the external terminal and the smart card control unit.

These and other advantages, aspects and novel features of the present invention will become more fully understood from the following detailed description and drawings, together with the details of the embodiments illustrated in this regard. .

The token of the present invention including a data flow control unit capable of automatically recognizing both a smart card and a storage medium (removable disk) eliminates the inconvenience of the user having to select a smart card or a storage medium through a direct switch operation. In addition, an application that expands the function of the smart card can be mounted and used on a storage medium (removable disk), thereby improving convenience of use.

In addition, the token of the present invention including a data flow control unit for automatically controlling the flow of data to recognize the storage medium (removable disk) prior to the smart card, the recognition time is relatively before the storage medium (removable disk) is recognized. The short smart card can be recognized first, greatly reducing the time required for smart card recognition.

1 is a schematic configuration diagram of a token including a data flow control unit according to an embodiment of the present invention, which is a schematic configuration diagram of a token having a SIM / MSD dual socket. FIG. 1 illustrates a subscriber identification module (SIM) card as a smart card and a micro secure digital (MSD) card as a removable disk. However, the present invention may be applied regardless of its name if it functions as a smart card or a removable disk. Do. In addition, FIG. 1 assumes a socket into which a SIM card or an MSD card is mounted one by one, but two or more such sockets may be provided as necessary.

Referring to FIG. 1, the token 100 having a SIM / MSD dual socket may include a socket 110 including a SIM socket 113 and an MSD socket 116, a SIM card controller 123, and an MSD card controller ( 126 and a data flow controller 127 to control the overall operation of the token 100, and a communication unit 130 for transmitting and receiving data with an external terminal.

First, the socket unit 110 will be described. The SIM socket 113 of the socket part 110 is mounted on a PCB (not shown) substrate installed in the token 100. The SIM socket 113 is a portion in which the SIM card 111 is coupled (mounted), and serves to connect the mounted SIM card 111 and the SIM card controller 123. The SIM socket 113 may have eight pins, and some pins (typically two pins) may serve to connect the SIM card 111 to a wireless antenna to be mounted.

The MSD socket 116 is also mounted on a PCB (not shown) substrate installed inside the token 100. The MSD socket 116 is a portion in which the MSD card 114 is mounted, and serves to connect the mounted MSD card 114 and the MSD card control unit 126.

Next, the control unit 120 will be described. The control unit includes a SIM card control unit 123, an MSD card control unit 126, and a data flow control unit 127.

The SIM card controller 123 is connected to the SIM socket 113 to control an operation related to the SIM card 111 coupled to the SIM socket 113. For example, when the token is coupled to an external terminal, the SIM card control unit 123 receives a predetermined command from an external terminal, reads the data of the SIM card 111, transmits the received data, or receives a predetermined command from an external terminal. A series of operations for recording data in 111 is controlled.

Similarly, the MSD card control unit 126 is connected to the MSD socket 116 to control operations associated with the MSD card 114 coupled to the MSD socket 116.

The data flow controller 127 is connected to the SIM card controller 123 and the MSD card controller 126 to control the flow of data transmitted / received to / from these cards. That is, when the SIM card 111 and the MSD card 114 are recognized through the external terminal, the external terminal automatically recognizes all these cards, but recognizes the data flow from the SIM card 111 having a relatively short recognition time. To control.

As an embodiment for the external terminal to recognize the data of the SIM card 111 before the MSD card 114, the SIM card control unit 123 is connected to port 1 of the data flow control unit 127, and the MSD card control unit ( 126 is connected to port 2 of the data flow controller 127. In general, since the external terminal controls the data flow to recognize the card connected to the port having the fastest number, when the SIM card controller 123 is connected to the port of the number that precedes the MSD card controller 126, the external terminal recognizes the SIM card first. Done.

By employing the data flow control unit 127 that automatically controls the data flow in the token 100 as described above, the external terminal can automatically recognize both the SIM card 111 and the MSD card 114. Convenience can be improved.

The external terminal does not recognize only one of the SIM card 111 and the MSD card 114, but can automatically recognize both cards simultaneously, so that the widget for expanding the function of the SIM card 111 can be supported. And other applications can be mounted on the MSD card 114 to be used.

As such, when the application for supporting the function expansion of the SIM card 111 is mounted on the MSD card 114, the user does not need to download the function expansion support application for each external terminal to which the token is combined, thereby improving convenience in use. In addition, since the usage history due to the download does not remain in the external terminal, there is an advantage that can be enhanced security.

Among the components of the token, the communication unit 130 plays a role of transmitting and receiving data with an external terminal. The communication unit 130 preferably includes both a wired communication unit 135 and an RF wireless communication unit 133 through the USB interface 135. The wired communication unit 135 may transmit and receive data of both the SIM card 111 and the MSD card 114, while the wireless communication unit 130 transmits and receives data of the MSD card 114. The wireless communication unit 133 is particularly useful for offline payment.

The wired communication unit 135 transmits data received from the data flow control unit 127 to an external terminal, or transmits data received from an external terminal to the data flow control unit 127, and the wireless communication unit 133 It transmits the data received from the SIM card control unit 123 to the external terminal or the data received from the external terminal to the SIM card control unit 123.

2 is a schematic structural diagram of a token having a SIM socket according to another embodiment of the present invention. Among the components shown in FIG. 2, a controller 220 including a SIM card controller 223, a storage medium controller 226, and a data flow controller 227, a USB wired communication unit 235, and an RF wireless communication unit 233 are provided. The communication unit 230, the SIM socket 213, and the like, play the same role as the components shown in FIG. 1. In this case, the storage medium controller 226 has an equivalent role to the MSD card controller 126 shown in FIG. 1.

However, the storage medium controller 226 is different from the MSD card controller 126 connected to the MSD card 114 via the MSD socket 116 in that the storage medium controller 226 is directly connected to the storage medium 214. Thus, the storage medium 214 is not connected to the storage medium controller 226 through a socket, but is fixedly mounted on the token internal PCB substrate and directly connected to the storage medium controller 226.

As used herein, the term " storage medium " refers to any medium that can only store data without a smart card function, which is preferably a memory capable of writing and erasing, in particular NAND flash memory.

2 illustrates a case in which the storage medium 214 is fixedly mounted on the token internal substrate, on the contrary, a token in which a smart card is fixedly mounted on the internal substrate and the storage medium is connected to the storage medium controller through a socket is also provided. It belongs to the scope of rights.

The control unit 320 and the communication unit 330 illustrated in FIG. 3 correspond to the control unit 120 and the communication unit 130 illustrated in FIG. 1, respectively. In addition, the smart card controller 323 and the MSD card controller 126 serve as the SIM card controller 123 and the storage medium controller 326 illustrated in FIG. 1.

However, unlike FIG. 1, the smart card 311 and the storage medium 314 are directly connected to the controllers 323 and 326 rather than indirectly through a socket. Therefore, the smart card 311 and the storage medium 314 is preferably fixedly mounted on the PCB substrate inside the token.

Hereinafter, an operation of a token including a data flow controller according to an embodiment of the present invention shown in FIG. 1 will be described with reference to FIGS. 4 and 5. 4 is a view for explaining the data acquisition operation of the token according to an embodiment of the present invention.

In step 430, the SIM card controller 123 and the MSD card controller 126 transfer the acquired data to the data flow controller 127. In step 440, the data flow controller 127 divides the received data into SIM card data and MSD card data and delivers the data to the communication unit 130, but the external terminal recognizes the MSD card data before the SIM card data. To control the data flow.

In operation 450, the communication unit 130 transmits the data received through the control of the data flow controller 127 to an external terminal through a wired or wireless channel. At this time, the external terminal that has received all the data of the SIM card 111 and the MSD card 114 through the wired communication unit 135 automatically recognizes all of these cards, but starts from the SIM card 111.
