- the second step corresponds to receiving a connection request during said second delay.
- the method comprises a step of monitoring at least a delay of reception of a downlink message from the server following the first transmission step, the triggering of a new first transmission step. being triggered if the reception time is exceeded.
- the method comprises a step of transmitting an upstream message to the server according to the second communication protocol following the connection establishment step and previously to the second reception step of a descending message;

- the first and / or the second protocol may be Raw IP type or other protocol above IP.
- the application exchanges may follow the transaction model, comprising a request and a response. Queries are sent as upstream messages, and responses as descendant messages. Thus, in a request and answer exchange in the form of a rising or falling message, only the response or only the request may contain useful data. A rising message and the downlink message sent back may contain useful data that does not necessarily correspond to the same transaction. For example, a request in progress requiring an application processing is transmitted as a rising message, and may trigger the transmission of a downlink message without useful data, or containing useful data relating to a previous request. In the same way, the application response corresponding to the current request can be sent during an exchange subsequent amount / message message.

- the field SERIAL includes the serial number of the electronic control unit U.
- the TIMESTAMP field includes a time stamp, for example a UNIX Timestamp corresponding to the number of seconds since EPOCH, calculated by the sender of the message.
- the block BODY has the following structure:
- the field ACTIVITYJNTERVAL corresponds to the maximum number of seconds between two activities of the electronic control unit U, that is to say a transmission to the server according to the first or the second communication protocol.

- the SEQUENCE block corresponds to an integer value (32 bits) representing the sequence number of the transmitted frame.
- Each transmitted message must contain a strictly increasing sequence number in order to avoid REPLAY attacks.
- Each actor of the communication (electronic control units and server) has his own sequence counter which he uses to number the message he sends.
- the first message transmitted must have a sequence number equal to 1.
- Sequence counters must be reset each time a new secret key is negotiated.
- control of the sequence number must use a sliding window mechanism, applying in particular the following control algorithm:
- Control windows must be reset each time a new secret key is negotiated.
- the SIGNATURE block corresponds to a signature of the message, arranged at the end of the message after the% separator in hexadecimal notation.
- Each transmitted message must have a signature
- the signature covers all the content of the message before the% non-included separator.
- the algorithm and the secret signature key must be negotiated beforehand via an HTTPS channel.
- the invention is not limited to the sole embodiment of this method and the system, described above as an example, it encompasses all the variants.
