Description

CARD CHIP ARCHITECTURE INTEGRATING PERIPHERAL

The invention relates to the internal architecture of a smart card integrating various types of device.

The invention notably proposes to increase the level of security of such a card and easier to use.

Smart cards with and / or without contact are for performing various operations such as, for example, banking, telephone communications, various identification operations, or télébiliétique type operations.

The majority of smart card manufacturing process is based on the assembly of an integrated circuit chip in a subset called micromodule which is connected to a communication interface and inset, that is to say placed in a cavity formed in the card body, using techniques known to those skilled in the art. The integrated circuit chip is a secure component can communicate only with a card reader.

The contactless cards have metallization flush with the surface of the card, arranged in a specific location of the card body, defined by the usual standard ISO 7816. These metallizations are designed to come in contact with a read head of a reader for an electric data transmission.

Contactless cards include an antenna for exchanging information with the outside through an electromagnetic coupling between the electronic map and a receiver or reader device. This coupling can be performed in playback mode or read / write mode, and data transmission is effected by radio frequency or microwave.

There are also hybrid cards or "co bicards" which have both metallizations flush with the surface of the card and an antenna embedded in the card body. This type of card can therefore exchange data with the outside is in contact mode or contactless. Devices that may be associated with a smart card are numerous. This is for example a display, a keyboard, a speaker or a piezoelectric vibrator, an RF communication interface, or components for measuring the environment such as temperature, ionizing radiation or the like, or biometric measurement of components such as a fingerprint sensor, a microphone and a voice processing system, or the like. These devices must necessarily communicate with the IC chip of the card in order to exchange data. However, the integrated circuit chips used in smart cards are secure components designed to establish communication only with a card reader.

Thus, in a standard architecture using standard components, communication between the IC chip of the card and any device is impossible. There are already smart cards incorporating one or more devices. In general, the IC chip is then designed to manage the embedded device. Thus, for each application, it is necessary to develop a new component for the integrated circuit to enable it to manage a screen, a keyboard or other predetermined device.

This solution, while effective, has a major drawback of the fact that we must develop and manufacture a different electronic component for each device application. Indeed, the proposed solution was to program the integrated circuit chip of the card to drive the device while retaining the secure features.

The present invention provides another solution for integrating devices with a smart card that allows to use standard secure components. Thus, the invention proposes to integrate a device manager with a reader function to interfacing with the secure component of the card. The reader function may be identical to those performed by a standard smart card readers.

According to one feature of the invention, the external communications interface of the card is shared between an external reader when the card is used as a conventional chip card and an integrated reader function in the device manager. The latter presents itself as a card reader for secure component.

The invention consists more particularly in a portable electronic device, of the smart card type, incorporating at least one device and having at least one secure component and an external communications interface, characterized in that it further comprises a device manager comprising at least one function of smart card reader to communicate with the secure element.

According to a preferred embodiment, the device management function is implemented by an executable program stored in the secure element.

According to one embodiment, the secure component comprises a plurality of executable programs for the implementation of different applications, each executable program including a specific portion of instructions to be executed by the device manager.

According to a feature, the device manager is a secure interface between the component and the user, and includes an application selection function allowing the latter to choose the application to be implemented.

According to a first embodiment, the secure component and the device manager are connected to the communication interface in parallel.

According to a feature of this embodiment, the device comprises disconnecting means or inhibiting the device manager when the external communication interface is requested to communicate with the secure element.

According to a second embodiment, the secure component has two ports of input-output communication, a first port for communication with the external interface and a second port for communication with the device manager.

According to a third embodiment, the secure component and the device manager are connected to the communication interface in series, the device manager managing data transmissions between the external interface and the secure component.

According to one characteristic, the device manager includes a transparent mode of operation when the interface of external communications is requested to communicate with the secure element.

According to the applications, devices are selected from a display, a keyboard, a biometric sensor.

The present invention enables a smart card integrating devices while using standard secure components, which represents a significant cost saving.

In addition, the architecture proposed by the present invention allows the user to secure components for different applications from a single device manager on the same standard card.

It is thus possible to develop smart card "multi-application" according to IC chips inserted into a single card.

In addition, the IC card obtained according to the present invention retains its characteristics and standards can be used as a conventional chip card.

Other features and advantages of the invention will appear on reading the following description given by way of illustrative and nonlimiting example and made with reference to the appended figures in which: Figure 1 is a diagram of the architecture of map according to a first embodiment of the invention;

Figure 2 is a diagram of the architecture of the card according to a second embodiment of the invention;

Figure 3 is a diagram of the architecture of the card according to a third embodiment of the invention;

The applications of the invention are many and varied.

For example, with a card equipped with a screen, you can view data outside a card reader infrastructure. The most direct application may be, for example, an electronic purse with display of balance on a screen, or a medical record smartcard direct and rapid visualization of certain data such as blood group or immunization record.

The principle of the invention, the devices are controlled by a device driver that provides an interface with the secure component of the card by behaving to him as a card reader.

The device manager includes a microprocessor for managing from peripheral signals. For example, on a smart card integrating a screen and a keyboard like devices, it is possible to display information on the screen by pressing the keyboard keys. The Device Manager receives a signal from the keyboard he deals by searching the corresponding information in the secure component.

Device manager comprises indeed an executable program that converts the signals from the peripheral card controller code chip. Device Manager behaves like a smart card reader with regard to the secure component.

According to a preferred embodiment, the executable program above is stored in the secure element. In this case, permanently stored data in the device manager can advantageously be limited to instructions for reading the secure component file containing said executable program and the instructions for starting the implementation of the program content in this file.

For example, it may be desirable to provide the device manager of a program that allows keyboard input of a numerical code, or the calculation of a biometric signature or otherwise. For example, it may be interesting to run the Device Manager a new biometric signature calculation algorithm or change the nature of the messages displayed on a screen.

Thanks to the invention, it is "possible to change content security programs in said secure component file. Access to this file can be read free, but the changes will be carried out by an authority having write access to this file, as the issuer of the card for example.

In the case of a "multi-application" card, the secure component comprises a plurality of executable programs able to implement different applications and transmit appropriate instructions to the device manager.

The Device Manager can advantageously be used as an interface between the component and secures the user so that it chooses the application implementation. It includes for this purpose a different application selection program. To secure this card "multi-application", the component has a secure application file for each file containing an executable program specific device management.

The interface between the component secures the card and the device manager can be organized in different ways, but nevertheless still using available signals on a standard component secures.

1 shows sche atically the architecture of the card according to a first embodiment 1 of the invention.

In this embodiment, the devices and the secure component manager are connected to the communication interface of the card in parallel.

In the example shown, the communication interface is formed by metal contact pads for an application has a chip card has contacts. However, an equivalent circuit may be considered for application to a map contactless chip, the communication interface then being formed by an antenna. The Device Manager has a smart card reader function to read and write data to a memory card. Preferably, upon insertion of the card into a card reader external chip, the device manager disconnects immediately contacts not to interfere with the transmission of external data. For this purpose, the device manager includes detection means (sensor) for connecting to an external drive, for example by detecting the supply voltage; as well as contacts disconnecting means, for example by means of a signal from the detection means of an external drive acting on the logic gates that will disconnect the contacts.

This embodiment advantageously allows a standard secure component without any changes.

2 schematically illustrates the architecture of the card according to a second embodiment of one invention.

In this embodiment, the devices and the secure element manager are also connected to the communication interface of the card in parallel.

This embodiment, however, uses a second port input / output generally present on secure but rarely used components. This second port of entry / exit is a direct interface between the secure component and device manager. However, it is necessary to integrate into the secure component at the time of its conception, the firmware necessary for the management of the second input / output port. This embodiment provides greater data security because the secure element control information circulating at the interface with the device manager. Such an architecture is also more flexible because it allows direct control of the information sent to the devices secure component.

3 schematically illustrates the architecture of the card according to a third embodiment of one invention. In this embodiment, device manager and the secure component are connected to the communication interface of the card in series, the filter device manager commands the secure component. This embodiment allows a simplification of the external interface of the smart card. Indeed, it is no longer necessary to share access to the secure component between the external communications interface and the device manager, the latter operating in a transparent mode when the card is inserted into an external reader.

For this purpose, detection means such as those previously described may be used. In contrast, there is provided means providing a direct connection between the secure component and the contacts, these means being controlled by a signal from the above detecting means in response to detection of an external drive. Moreover, this architecture is particularly advantageous in the context of an application of non-contact IC card when the external card is of the radiofrequency type interface. Indeed, the device manager being located between the external interface and the secure component, it may be able to handle interrupts from any device and an external communication terminal in accordance with predetermined priorities.
