The electrical quantity is for example the voltage of an electrical conductor, respectively the intensity of an electric current, and the measurement sensor 12 is then called voltage sensor, respectively current sensor. As a variant, the thermodynamic quantity is, for example, a temperature, respectively a pressure, and the measurement sensor 12 is then called a temperature sensor, or a pressure sensor, respectively.
    [0005] In another variant, the measurement sensor 12 is adapted to measure an environmental quantity, such as a pH, an oxygen content, a particle density (carbon monoxide, carbon dioxide, dust). Each measuring sensor 12 comprises a first radio transceiver 20 able to communicate with the communication gateway 16 via a first data link 22. Each measurement sensor 12 comprises a first information processing unit 24, formed for example by a first processor 26 and a first memory 28 associated with the first processor 26, as shown in Figure 1 where a single sensor 12 is shown in detail for the sake of simplification of the drawings. The first information processing unit 24 is connected to the first radio transceiver 20. The computer server 14 comprises a first data transmission member 30 able to communicate with the communication gateway 16 via the communication network 18 forming a second data link 32.
    [0006] The computer server 14 comprises a second information processing unit 34, formed for example of a second processor 36 and a second memory 38 associated with the second processor 36. The second information processing unit 34 is connected to the second processor 36. transmission member 30. The computer server 14 is able to receive data relating to the different quantities measured by each of the measurement sensors 12. In other words, the computer server 14 makes it possible to centralize the different values measured by the sensors 12, in order to to centrally monitor these measured values. The computer server 14 is for example a web server. The references of the computer server 14, such as the name or the IP address of the server, are for example stored in the first memory 28 of the sensor, to be transmitted by the sensor 12 to the gateway 16 when the sensor 12 asks the gateway The communication gateway 16 is connected, on the one hand, to each of the measurement sensors 12 via the first respective data links 22 and, on the other hand, to the computer server 14 via the second data link 32 formed by the communication network. The communication gateway 16 functionally forms a communication router between a respective measurement sensor 12 and the computer server 14, the data exchanged between the corresponding measurement sensor 12 and the computer server 14 only passing through the communication gateway 16, after establishment of a communication between the communication gateway 16 and the computer server 14. The communication gateway 16 comprises a second radio transceiver 40 able to communicate with each sensor 12 via the corresponding first data link 22, in particular with the first radio transceiver 20 of each measurement sensor. In other words, the communication gateway 16 is connected to the measurement sensor 12 via a local communication network formed by the first transceiver 20, the first link 22 and the respective second transceiver 40. The local network is, for example , compliant with the IEEE 802.15.1 standard, also known as the Bluetooth standard, or the IEEE 802.15.4 standard, also known as the ZigBee standard.
    [0007] The communication gateway 16 also includes a second data transmission member 42 able to communicate with the computer server 14, in particular with the first transmission member 30 of the computer server. The communication gateway 16 is then able to communicate remotely with the server 14.
    [0008] The communication gateway 16 comprises means 44 for transferring data between the sensor 12 and the computer server 14. The data transmission between the gateway 16 and the server 14 is preferably carried out on the basis of the IP protocol. English Internet Protocol). The transmission of data between the gateway 16 and the sensor 12 is preferably carried out on the basis of a local communication protocol, such as the ZigBee or ZigBee Green Power protocols in accordance with the IEEE 802.15.4 standard, the MODBUS protocol. , the CAN (Controller Area Network) protocol compliant with the ISO 11898 standard, the BACnet protocol, or the KNX protocol. Once communication is established between the gateway 16 and the server 14, the gateway 16 only provides the necessary transformation between the protocols used, on the one hand between the sensor 12 and the gateway 16, and on the other hand between the gateway 16 and the server 14, and focuses on transmitting the useful information without modification. The modifications made by the gateway 16 concern only the transition from one protocol to another. In addition, the transfer means 44 are also responsible for establishing an initial connection between the gateway 16 and the server 14 at the initiative of the sensor 12, in order to allow the secure connection of the measurement sensor 12 to the computer server. 14, the entire chain of communication between the sensor 12 and the server 14 via the gateway 16 is then secure. The communication gateway 16 is, for example, integrated in a mobile electronic device 46, such as a mobile phone, a tablet or a laptop. The transfer means 44 are then preferably in the form of software capable of being stored in a memory 48 of the mobile phone 46. The references of the computer server 14, such as the IP address of the server, are alternatively stored in the memory. memory 48 of the mobile telephone The communication network 18 is known per se. The communication network 18 is for example the Internet network. The first data link 22 is a radio link, preferably a short-range radio link, i.e. for distances of the order of a few meters or a few tens of meters.
    [0009] The first data link 22 is, for example, in accordance with the IEEE 802.15 standard, also known as the Bluetooth® standard. In a variant, the first data link 22 complies with the IEEE 802.11 standard, also known as the Wi-Fi standard, the measurement sensors 12 and the communication gateway 16 forming, for example, an ad hoc network. The first and second radio transceivers 20, 40 are known per se, and conform to the same radio standard as the first data link 22. The first memory 28 is able to store a first data exchange software 50 with the computer server 14, preferably via the gateway 16, the data exchange software 50 being connected to the first radio transceiver 20.
    [0010] The first memory 28 comprises according to the invention secure connection information to the computer server 14, said connection information comprising a 52 sensor authentication code. The connection information is preferably protected by an access control member, not shown. The access control member is adapted to be stored in the first memory 28, and is for example able to require the provision of a password to allow access to the connection information. The first memory 28 is able to store a software 54 for generating a response to a request from the computer server 14, the response being elaborated according to the authentication code 52. In addition, the first memory 28 is able to store a first cryptographic software 56 capable of encrypting data intended to be transmitted to the computer server 14 by the data exchange software 50 and / or to decrypt encrypted data received from the computer server 14. Data exchange 50, response generation means 54 and first cryptographic means 56 are implemented as programmable logic components, or as dedicated integrated circuits. The first data transmission member 30 is adapted to receive data from each measurement sensor 12 via the communication gateway 16 and the communication network 18, and also to send data to each measurement sensor 12 via said gateway 16 and said network 18. The first data transmission member 30 is adapted to establish a secure connection with the communication gateway 16 on request of the communication gateway 16 and without it being authenticated. Securing the connection between the gateway 16 and the server 14 does not involve information from the sensor 12. The second memory 38 is able to store a first software 60 sending an authentication request to each measurement sensor 12, and a response authentication software 62 developed by each measurement sensor 12 following the receipt of said request.
    [0011] In addition, the second memory 38 is able to store a second software 64 for sending, to each authenticated sensor 12, an encryption key adapted for the subsequent encryption of data exchanged between the computer server 14 and the authenticated sensor 12. In addition, the second sending software 64 is able to send the encryption key to the gateway 16 from the beginning of the communication between the sensor 12 and the server 14 for the subsequent encryption of data exchanged between the computer server 14 and the server. gateway 16.
    [0012] The second memory 38 is capable of storing a second cryptographic software 66 capable of encrypting data intended to be transmitted to a corresponding measurement sensor 12 and / or of decrypting encrypted data received from said measurement sensor 12. The second memory 38 is capable of storing a second data exchange software 68 with each measurement sensor 12, the second data exchange software 68 being connected to the first transmission member 30. In a variant, the first sending means 60, the authentication means 62, the second sending means 64, the second cryptographic means 66 and the second data exchange means 68 are made in the form of programmable logic components or in the form of dedicated integrated circuits. The second memory 38 includes a database 70 containing information relating to each of the measurement sensors 12, including the authentication codes 52 of the different sensors. The second data transmission device 42 is adapted to receive data from the computer server 14 via the communication network 18, and also to send data to the server 14 via the said network 18. The communication gateway 16 is preferably connected to the communication network 18 by radio waves, and the second transmission member 42 is for example compliant with the IEEE 802.11 standard (Wi-Fi standard), or the UMTS (Universal Mobile Telecommunications System), also called the 3G standard for the third-generation mobile telephony standard, or the LTE (Long Term Evolution) standard, also known as the 4G standard for the fourth-generation mobile telephony standard. The operation of the measuring installation 10 according to the invention will now be described with reference to FIG. 2 representing a flowchart of the data exchange method according to the invention, between a corresponding measuring sensor 12 and the computer server 14 via the communication gateway 16. During an initial step 90, the measurement sensor 12 starts by requesting from the gateway 16 the establishment of a connection between the sensor 12 and the gateway 16, this connection being able to not be secure. In the next step 95, the communication gateway 16 validates that the communication is well established between the sensor 12 and the gateway 16. On request of communication of the sensor 12 which transmits thereto the authentication code 52, the Gateway 16 will ask, during a step 96, the establishment of a secure communication with the server 14 with which the sensor 12 wishes to exchange data. Alternatively, the name and / or address of the server 14 are provided by the gateway 16. In the next step 97, the server 14 validates the secure connection between it and the gateway 16, and informs the gateway 16 to with the aid of its second sending software 64. Following the validation of the establishment of the secure connection with the server 14, the communication gateway 16 transmits, during the step 98 and the server 14, the code d authentication 52 associated with the sensor, the latter having been previously provided to the gateway 16 by the sensor 12.
    [0013] In the next step 99 and following receipt of the authentication code 52 associated with the sensor, the server 14 verifies that the sensor 12 is well known and authorized. Following receipt of this initial connection request from the measurement sensor 12, the server 14 prepares in step 110 a specific request for this sensor 12 using the information contained in its database 70. In other words, this step 110 corresponds to the preparation of a challenge by the server 14 for the measurement sensor 12 concerned for the encryption of data that will subsequently be exchanged between the sensor 12 and the server 14. The server 14 sends then, using its first sending software 60 and during step 120, the authentication request created in the previous step, via the communication gateway 16 to the measurement sensor 12 having sent its connection request. This step 120 corresponds in other words to the sending, by the server 14, of the challenge prepared in step 110 to the sensor 12 concerned. After receiving this authentication request from the computer server 14, the measurement sensor 12 then elaborates, by means of its production software 54 and in step 130, the response to said request for authentication, this response being developed according to the authentication code 52 associated with the sensor 12. The elaboration of the response consists, for example, in encrypting the authentication request received with said authentication code 52 as a key encryption. In other words, this step 130 consists, after reception of the challenge by the sensor 12, in the generation of the response and in the encryption thereof by the sensor 12. The measurement sensor 12 then transmits, with the aid of its first exchange software 50 and during step 140, the response developed in the previous step, to the computer server 14 and via the communication gateway 16. This step 140 corresponds in other words to the sending by the sensor 12, via the gateway 16 and to the computer server 14, the encrypted response to the previously received challenge.
    [0014] When the server 14 receives this response from the sensor 12 to which the request has been sent, the server 14 checks, in step 150 and using its authentication software 62, whether the response received is in accordance or not, by comparing the authentication code 52 that made it possible to elaborate the response with the authentication code contained in its database 70 for this sensor 12. In other words, the step 150 corresponding to the validation by the server 14 of the response to the challenge sent by the sensor 12, and in the case of a positive validation to maintain a secure connection between the gateway 16 and the server 14 on the one hand, and between the gateway 16 and the sensor 12 on the other hand.
    [0015] The verification of the response received consists, for example, in decrypting the response received with the authentication code contained in the base 70 as a decryption key, and then comparing the decrypted response with the authentication request sent. In this case, the check is positive when the decrypted response is identical to the authentication request previously sent.
    [0016] In case of positive verification, a data exchange session is then opened between the server 14 and the authenticated sensor 12, and the secure connection between the gateway 16 and the server 14 is maintained. Alternatively, the server 14 sends, to the sensor 12 which has just been authenticated, a specific encryption key of said authenticated sensor, using its second sending software 64 and in step 160. From this step 160, the gateway 16 only plays a role of transformation of communication protocols, between the communication protocol used between the sensor 12 and the gateway 16 on the one hand and the communication protocol used between the gateway 16 and the gateway 16. server 14 on the other hand.
    [0017] This encryption key, also called session key, is for example a symmetric key adapted for the encryption / decryption of the data that will be exchanged during the data exchange session. The session key is preferably sent in encrypted form by the server 14, the encryption of the session key being for example carried out using the authentication code 52.
    [0018] In the next step 170, the authenticated sensor 12 then stores the encryption key received in its first memory 28, for later use when sending encrypted data to the computer server 14. The measurement sensor 12 is connected to the computer server 14, and is then able to transmit regularly to the computer server 14 successive values of the measured quantity, and this in an encrypted manner using the session key.
    [0019] The measurement sensor 12 then sends to the computer server 14, during the step 200 with the aid of its first exchange software 50 via the communication gateway 16, an encrypted message containing one or more values of the measured quantity, the message having been encrypted by the first cryptography software 56 with the previously received session key. In step 210, following receipt of this encrypted message from the authenticated sensor 12, the server 14 begins by decrypting the received message using its second cryptography software 66 and with the session key previously sent to said sensor. The server 14 then records, in its second memory 38, the value or values of the measured quantity contained in the message that has just been decrypted. The server 14 finally sends, during step 220, an acknowledgment message to the corresponding sensor 12. Following receipt of this acknowledgment message, said sensor 12 returns to step 200 to subsequently send at least one other value of the measured quantity. In a variant, depending on the ciphering technologies used, steps 110 and 150 are grouped together, and steps 120 and 160 are also grouped together. According to this variant, the steps of the method are then linked in the following manner starting from step 110. Step 110, grouped with step 150, includes checking the identity of the sensor 12 and preparing it. of the challenge, this challenge comprising the encryption key to be used for the subsequent step 200. Step 120, grouped with step 160, comprises sending the challenge containing the encryption key. Step 130 comprises the validation of the challenge by the sensor 12, as well as the recording, by the sensor 12 in its memory 28, of the encryption key contained in the challenge received, and for the purpose of subsequent communications between the sensor 12 and the server 14 from step 200. If the measurement sensor 12 no longer has a measured value to transmit to the computer server 14, the sensor 12 closes, in step 230, the connection with the gateway communication 16 which itself closes its connection with the server 14.
    [0020] The measuring installation 10 according to the invention and the associated data exchange method thus allow a secure exchange of data from the measurement sensor 12 to the computer server 14, and vice versa from the server 14 to the server 14. sensor 12, this being due to the fact that the connection information, in particular the authentication code 52, are contained directly in the first memory 28 of the measurement sensor.
    [0021] With the state-of-the-art measuring system, data exchange is secured only between the communication gateway and the server, and the data exchanges are not protected between the communication gateway and the measurement sensor.
    [0022] The measuring installation 10 according to the invention and the associated data exchange method thus make it possible to establish a secure communication from the sensor 12 to the server 14, and not only between the gateway 16 and the server 14. They also make it possible to propose this secure communication between the sensor 12 and the server 14 via the communication gateway 16 which is not a trusted component, and to allow the communication gateway 16 to establish the secure connection with the server 14 by using security parameters associated with the sensor 12, that is to say the connection information comprising the authentication code 52. The communication gateway 16 has an ability to communicate locally with the sensor 12, an aptitude communicating remotely with the computer server 14, an ability to execute an application capable of establishing a secure communication between the sensor 12 and the server 14 following the establishment of one or more secure connections. In the embodiment of Figure 2, two secure connections are established, a first between the sensor 12 and the gateway 16, and a second between the gateway 16 and the server 14 on the basis of the connection information stored in the first memory 28 of the sensor. Those skilled in the art will also understand that for the same sensor 12 or the same group of sensors 12, the mobile communication gateway 16 is not necessarily always the same, a new gateway 16 being able to be used at each new data transmission by the sensor (s) 12.
    [0023] The authentication mechanism with the development according to the authentication code 52 of the response to the authentication request from the server 14 also makes it easier to implement the securing of this data exchange, and it In particular, it is not necessary to configure a virtual private network between the communication gateway 16 and the computer server 14.
    [0024] In general, the data exchange method according to the invention requires a minimum interaction between the measurement sensor 12 and the communication gateway 16, since it is only necessary for the sensor 12 to open a connection with the gateway. communication 16 prior to sending the connection request to the server 14, then close this connection with the gateway 16 when the data exchange with the server 14 is completed, the data only passing through the communication gateway 16 during this data exchange.
    [0025] It is thus conceivable that the measurement sensor 12 according to the invention makes it possible to improve the security of the data exchanged with the computer server 14 via the communication gateway 16, while simplifying the implementation of this security of the data exchange. .5
