    [0001] A method of managing information communication between an NFC controller and a secure element within an apparatus, and corresponding NFC apparatus and controller Embodiments of the invention relate to communication between components or elements, in particular between a non-contact element, for example a NFC (Near Field Communication) controller element, at least one element, such as a UICC or secure element and a host device, for example located in a wireless device, for example a mobile phone. In addition to its traditional telephone function, a mobile phone can be used to exchange information with a contactless device using a contactless communication protocol. This allows the exchange of information between the contactless device and elements located in the mobile phone. Many applications are thus possible, such as the payment of a mobile ticket in public transport (the mobile phone acts as a ticket) or mobile payment (the mobile phone acts as a credit-debit payment card). Near Field Communication (NFC) is a short-range, high-frequency wireless communication technology that allows the exchange of data between two non-contact devices over a short distance, for example 10 centimeters. NFC is an open platform technology defined in ISO / IEC 18092 and ISO / IEC 21481, but includes many pre-existing standards, including ISO / IEC 14443 Type A and Type B.
    [0002] NFC device solutions typically include a host device, an NFC controller, and one or more secure elements.
    [0003] The standard communication mode between the host device and the secure element is to use the same link, for example an SWP link, as the link used for contactless communication. But such a link has a limited bandwidth.
    [0004] However, in some use cases, a greater bandwidth is required to allow communication between the host device and the secure element, for example in the case of data transfer relating to a fingerprint for the user. identification of the user.
    [0005] According to one embodiment, a method and an apparatus are provided for enabling communication between a host device and at least one secure element that requires a greater bandwidth than that supported by the link, for example the SWP link, used for exchange information relating to contactless communication (wireless). In one aspect, a method is provided for managing the communication of information between an NFC controller coupled to an antenna for contactless communication with an object, to a host device and to at least one secure element.
    [0006] According to this aspect, said method comprises routing (routing) all said information through said NFC controller, communicating first information to be communicated between said at least one secure element and said host device through a first communication link between said NFC controller and said host device and through a second communication link between said NFC controller and said at least one secure element, communicating second information from and / or to said antenna through a third communication link between said NFC controller and said at least one secure element, said first and second communication links having bandwidths greater than the bandwidth of said third communication link.
    [0007] Thus, according to this aspect, another link is provided between the NFC controller and the secure element, which is different from the link used for the RF (contactless) communication and which has a bandwidth greater than the bandwidth of the NFC. link used for RF communication. This additional link is intended to be used to exchange information between the host device and the secure element with a high bit rate. In addition, the NFC solution proposed here is a solution centered on the NFC controller, that is to say a solution in which all the information communicated between all elements of the NFC solution pass through the NFC controller and all operations. routing of different kinds of information are performed inside the NFC controller. According to one mode of implementation, the third communication link is an SWP link. An SWP link is a link or line adapted to support the "Single Wire Protocol" (SWP) protocol, ("single-wire protocol"). Said second communication link can be a type 20 SPI or I2C bus or UART or USB. According to one embodiment, said first communication link is a bus of the SPI or I2C or UART type and said first information is exchanged on said first communication link using an NCI type communication protocol (abbreviation of NFC Controller Interface, "NFC Controller Interface"). Said first information may comprise information exchanged using the NFCEE APDU protocol of said NCI type communication protocol.
    [0008] APDU is a classic acronym for "Application Protocol Data Unit". Another possibility is that said first information comprises information exchanged using the transparent NFCEE protocol of said NCI type communication protocol.
    [0009] By using this transparent NFCEE protocol, it is thus possible to exchange either APDU messages, such as those that comply with the NFCEE APDU protocol, or proprietary messages that comply with a proprietary communication protocol.
    [0010] According to one embodiment, the method further comprises communicating on said first and third communication links third information to be communicated between said at least one secure element and said host device. Said third information may include information communicated using an HCI access protocol of said NCI type communication protocol. In another aspect, a device is provided comprising an antenna for non-contacting communication with an object, a host device, at least one secure element, and an NFC controller.
    [0011] The NFC controller comprises: a first input / output means coupled to said host device via a first communication link configured to convey first information to be communicated between said at least one secure element and said host device, a second means input / output signal coupled to said at least one secure element via a second communication link configured to convey said first information, third input / output means coupled to said at least one secure element via a third communication link configured to carry second information from and / or to said antenna, fourth input / output means coupled to said antenna, said first and second communication links having bandwidths greater than the bandwidth of said third communication link, and routing means configured to route (route) said first information between said first and second input / output means and for routing said second information between said third and fourth input / output means.
    [0012] According to one embodiment, the third communication link is an SWP link and the third input / output means comprises an interface of the HCI type. According to one embodiment, the second communication link is a bus of the SPI or I2C or UART or USB type and said second input / output means comprises a bus interface adapted to the type of said bus. According to one embodiment, the first communication link is a bus of the SPI or I2C or UART type configured to support a communication protocol of the NCI type and said first input / output means comprises a bus interface adapted to the type of said bus. According to one embodiment, said first and third communication links are further configured to convey third information to be communicated between said at least one secure element and said host device and said routing means is further configured to route said third information between said first and third input / output means. The secure element may be a UICC or an integrated secure element. In another aspect, an NFC controller is provided, comprising: first input / output means configured to be coupled to a host device for receiving and / or transmitting first information to be communicated between at least one secure element and said host device, second input / output means configured to be coupled to said at least one secure element for receiving and / or transmitting said first information, third input / output means configured to be coupled to said at least one element secure to receive and / or transmit second information from and / or to an antenna adapted for non-contacting communication with an object, a fourth input / output means configured to be coupled to said antenna, said first and second input / output means having bandwidths greater than the bandwidth of said third means input / output device, and routing means configured to route said first information between said first and second input / output means and to route said second information between said third and fourth input / output means.
    [0013] According to one embodiment, said third input / output means comprises an interface of the HCI type. According to one embodiment, said first input / output means comprises a bus interface of the SPI or I2C or UART type configured to support a communication protocol of the NCI type. According to one embodiment, said first and third input / output means are further configured to receive and / or transmit third information to be communicated between said at least one secure element and said host device and said routing means. is further configured to route said third information between said first and third input / output means. Other advantages will become apparent from the embodiment exam, these being appended in which: FIGS. 1 to 6 relate to particular embodiments of the invention. Figure 1 shows a WP device adapted to the NFC, for example an NFC mobile phone.
    [0014] The apparatus WP comprises a DIS device comprising a contactless front end element NCC, for example an NFC controller, which is responsible for wireless (non-contact) communication, for example radio frequency (RF communication), with a and features of the invention the detailed description of modes in no way limiting, and RDR external RF reader designs or an external tag or other peer NFC device via ANT1 antenna. The contactless communication protocol is for example that described in ISO / IEC 14443-4. The device also includes a secure element SE connected to the NFC controller NCC. A secure element is for example an element adapted to contain secure or protected information, for example banking information, information concerning a telephone subscription ...
    [0015] The secure element SE may be an embedded secure element, for example totally incorporated in an integrated circuit containing the NFC controller, and for example housed with said NFC controller. In other words, said secure element SE can be incorporated permanently into the mobile phone, that is to say without the possibility of being removed. As a variant, the secure element SE may be a removable secure element, for example a UICC providing the network subscription (SIM and USIM applications) and RF applications using the ISO / IEC 14443-4 protocol layer in operating mode. card emulation.
    [0016] As defined by ETSI TR 102 216 V3.0.0 (2003-09), "UICC", which is neither an abbreviation nor an acronym, refers to a smart card that conforms to the features written and maintained by the project. Smart Card Platform (ETSI).
    [0017] The WP mobile phone also includes a DH host device responsible for managing the NFC controller as well as user inputs and network communication. As shown in FIG. 1, the NFC controller NCC is coupled to the host device DH by a first communication link LK1, for example a bus of the SPI type. The NFC controller NCC is coupled to the secure element SE by means of a second communication link LK2, for example a bus of the SPI type, and of a third communication link LK3, for example an SWP link.
    [0018] Although an SWP link is described here, other types of LK3 links can be used, including links able to support proprietary protocols such as the DCLB ("Digital Contactless Bridge") or the NFC-WI 5 interface (wired NFC interface). The bandwidths of all these types of links or interfaces are up to a few megabits per second (for example: SWP up to 1.7 Mbps, DCLB up to 848 kbps, WI up to 848 kbits / second). s). The first and second communication links LK1 and LK2 are chosen to have a bandwidth greater than the bandwidth of the third communication link LK3. Such a link can be for example a bus of the SPI type, or I2C, or UART or USB, and the bandwidth of such a link can be up to 26 Mbps.
    [0019] The coupling between the host device DH, the NFC controller NCC and the secure element will now be described in more detail with particular reference to FIG. 2. The NFC controller NCC comprises: a first input / output means I01 coupled to the DH device via the first communication link LK1, a second input / output means 102 coupled to said secure element SE via the second communication link LK2, a third input / output means 103 coupled to the secure element SE via the third communication link LK3 and 25 - a fourth input / output means 104 coupled to the antenna ANT1. It should be noted that the bandwidth of a link is also the bandwidth of the input / output means coupled to this link. As indicated above, the third communication link LK3 is an SWP link. An SWP link is a link or line adapted to support the single-wire protocol (SWP). The single-wire protocol (SWP) is a bit-to-point and point-to-point communication protocol between a secure element and a non-contact front end, and is described in ETSI TS 102 613, for example in its V7 version. .7.0 (2009-10). If necessary, a person skilled in the art can refer to this standard. More specifically, as illustrated in FIG. 3, the NFC controller NCC is the master while the secure element SE is a slave. The master and a slave are connected to each other by the SWP LK link. As described in ETSI TS 102 613, the single-wire protocol (SWP) principle is based on simultaneous bidirectional digital information transmission. The signal Si is transmitted from NCC to SE by digital modulation (L or H) in the voltage domain while the signal S2 is transmitted from SE to NCC by digital modulation (L or H) in the current domain.
    [0020] When the master sends SI to state H, then the slave can draw a current (state H) or not (state L) and thus transmit S2. With binary encoding of S1 by pulse width modulation, it is possible to transmit a transmission clock, as well as data in simultaneous bidirectional mode. More details can be found in ETSI TS 102 613. The SWP link uses a Host Controller Interface (HCI) as described in ETSI TS 102 613 and ETSI TS 102 standards. In other words, the input / output means 103 of the NFC controller and the input / output means 1030 of the secure element include HCI type interfaces. As stated in ETSI TS 102 622, for example in version 11.00 (2011-09), the HCI interface defines the interface between the NFC controller and the secure element. Specifically, the HCI interface has three levels: - a set of gates that exchange commands, responses and events, - an HCP (Host Controller Protocol) messaging mechanism, and - an HCP routing mechanism that can optionally segment the messages if necessary. In particular, the HCP protocol requires that the underlying data link layer (eg SWP) be error-free and that the order of the received or sent data be respected. As explained in ETSI TS 102 613, the LLC layer ("Logical Link Control") is in charge of error handling and flow control while the MAC layer ("Medium Access Control ":" Media Access Control ") is in charge of timing on the SWP LK1 link. Among the three link control layers defined in ETSI TS 102 613 are the LLC layer called SHDLC (Simplified High Level Data Link Control) and the layer CLT ("Contactless 15 Tunneling": "tunneling" without contact). In reality, the SWP link LK3 uses a logical channel (or pipe) to drive respectively the data that comes from and that is intended for RF communication between the reader or the label. As for the DH host device, it generally includes a MPR processor which is responsible for managing the NFC controller and managing a user input. This host device DH further comprises an input / output means 1010 coupled to the first communication link LK1. The input / output means 101 of the NFC controller NCC and the input / output means 1010 of the host device include, for example, NCI type interfaces (NFC controller interface). The communication protocol called NCI, between an NFC controller and a host device, is described for example in the document entitled NFC Forum-TS-NCI-1.0_candidate_1, April 12, 2012. The person skilled in the art may refer to this document if necessary. The link LK1 can be for example a bus of the type I2C, UART or SPI.
    [0021] The communication link LK2 here is a bus of the SPI type. However, this bus could also be a bus type I2C, UART or USB. Likewise, the second input / output means 102 and the corresponding input / output means 1020 of the secure element SE comprise a bus interface corresponding to the bus type LK2, here a bus interface of the SPI type. The fourth input / output means 104 of the NFC controller NCC is coupled to the antenna ANT1 and conforms to the NFC protocols used for RF communication with the RF reader, tag, or other peer NFC device. The secure element SE also comprises a first processing means MT1 coupled to the input / output means 1030 for processing the information relating to the RF communication with the antenna ANT1, and a second processing means MT2 coupled by means of input / output 1020 for processing information exchanged on the second communication link LK2. Although the secure element SE is here an embedded secure element, it could also be a UICC.
    [0022] The UICC is also connected to the NFC controller by an SWP link which uses an HCI interface (Host-Controller Interface), as described in ETSI TS 102 613 and ETSI TS 102 622. Figure 4 shows an embodiment of the physical link between the NFC NCC controller and a UICC. Specifically, as shown in this figure and as explained in ETSI TS 102 613, the UICC contact C6 (I030) is connected to the SWIO port (I03) of the NFC NCC for transmission of signals S1 and S2. . Further, in such a case, the second communication link LK2 is a USB bus connected between the second input / output means 102 of the NFC controller NCC and the contacts C4 and C8 of the UICC which form the means of communication. input / output 1020. As can be seen more particularly in FIG. 2, all the information exchanged between the host device DH, the secure element SE and the antenna ANT1 passes through the NFC controller NCC and is routed between the corresponding input / output means by the RM routing means that can be achieved by one or more software module (s).
    [0023] More precisely, the first information communicated between the secure element and the host device is communicated via the first communication link LK1 and via the second communication link LK2. The second information INF2 from and / or to said antenna ANT1 is communicated via the third communication link LK3. More precisely, the routing means RM extracts the second information INF2 from the frames received at the first input / output means I01 according to an NFC protocol and arranges these second information INF2 in accordance with the characteristics of the interface HCI 103. to be transmitted on the SWP LK3 link. Reverse processing is performed for the second information received at the HCI interface 103 and intended to be transmitted through the fourth input / output means 104. The first information to be exchanged between the host device DH and the the secure element SE are, for example, data relating to a fingerprint, which may or may not be encrypted, and which may for example be compared with a reference fingerprint stored in the secure element in order to send back to the host device a result of this concordance check. The first information INF1 is exchanged on the first communication link LK1 using, for example, a communication protocol of the NCI type.
    [0024] Several protocols can be used. For example, the first information can be exchanged using the protocol called APDU NFCEE of the NCI type communication protocol.
    [0025] One of ordinary skill in the art can consult the NCI document mentioned above for further details on the NFCEE APDU protocol or interface. Briefly, the communication employed in this protocol 5 uses the sending and receiving of APDU command response pairs. Each APDU command contains a data packet header followed by a payload that contains the data field. When the routing means RM receives such an APDU command, it extracts the information it contains and encapsulates them according to the transport format required by the link LK2, for example the SPI bus. Instead of using the NFCEE protocol or APDU interface, the first information on the first LK1 communication link can be exchanged using the transparent NFCEE protocol of said NCI communication protocol. This transparent protocol or interface (e) is used by the host device to communicate with the secure element connected to the NFC controller by exchanging data which is not understood by the NFC controller but which is simply transferred without modification. When the NFC controller RM routing means receives this type of message, it extracts and re-routes the payload of the data messages in the appropriate message format directly to the input / output means 102 without any modification.
    [0026] In the other direction, when a message from the secure element is received at the second input / output means, the routing means extracts the data from the message, loads it into the payload of a message of data and sends the data message to the host device on the first communication link LK1.
    [0027] For the communication between the secure element SE and the host device DH, third information INF3 can be exchanged using the third communication link LK3 (SWP) and the first communication link LK1. These third information INF3 are, for example, connectivity events which are events defined by a host-controller interface (HCI) at the end of an RF transaction. The secure element may for example send to the host device an indication that an RF transaction is actually completed.
    [0028] The third information may therefore include information communicated using an HCI access protocol. And when the RM routing means of the NFC controller NCC receives these third information using the access protocol HCI on the first communication link LK1, it extracts the information contained therein, encapsulates them according to the HCI protocol supported by the link SWP LK3 and routes this message on the link LK3 via the third input / output means 103. Now let us take a closer look at FIG. 5 to illustrate an example of an interface activation and management procedure. routing. To activate the interfaces, a special procedure called the NFCEE discovery procedure described in the NCI document mentioned above can be used. According to this procedure, the host device DH first sends a command named NFCEEDISCOVER_CMD to the NFC controller NCC. In response to this command, the NFC controller sends a response command called NFCEE DISCOVER RESP. The NFC controller then triggers the conventional activation of the SPI bus and once everything is in order for the secure element, the secure element sends a response indicating that the SPI link is established. The NFC controller also triggers the activation of the SWP link and when this activation is completed according to the SWP characteristics, a response indicating that the SWP link is established is sent to the NFC controller.
    [0029] Next, the NFC controller sends to the host device two responses called NFCEE_DISCOVER_NTF. Each of these commands contains in the payload field an identification indication Id of the specific protocol or interface supported by the second communication link LK2 and the third communication link LK3. Although there is only one secure element connected to the NFC controller by two separate links LK2 and LK3, this configuration is seen by the discovery procedure as two separate secure elements that support two different interfaces respectively. Once the interfaces have been activated, the exchange of the third information INF3 is performed according to the access protocol NFCEE HCI, whereas, in this example, the exchange of the first information between the secure element SE and the host device is performed using the NFCE APDU interface. The use of two different communication links LK2 and LK3 makes it possible to send first information INF1 and second information INF2 in parallel, for example in an interlaced manner, without waiting for example the end of an RF session.
    [0030] Furthermore, as illustrated in FIG. 6, this configuration is compatible with a low-power mode in which the secure element is powered by the NFC controller NCC which is itself powered by the magnetic field received by the ANTI antenna. during an NFC communication with the reader or the contactless label, and not with the battery of the apparatus. In such a low power mode, the second information INF2 can still be transferred through the NFC controller and the third link LK3. Although only one secure element SE has been described above, it is possible to connect several secure elements (for example two) to the NFC controller via several second links LK2 and several third links LK3 respectively to the input means. output 102 and 103 using for example multiplexers present in the input / output means 102 and 103.
    [0031] In addition, during the discovery procedure, an identifier for each protocol supported by each secure element is provided to the host device. During the exchange of information, the NFC controller RM routing means route the information accordingly between the corresponding input / output means while controlling the multiplexer (s).
