In a specific embodiment, after receiving the random number and the serial number sent by the remote control key, the BCM (i.e. the device for executing the dual authentication matching method of the remote control key) generates second request data according to the serial number, and combines the serial number and the second request data into a serial number inquiry authenticity request (i.e. authenticity inquiry data), firstly, the serial number inquiry authenticity request generated by the BCM of the vehicle body controller is sent to the TBOX through the CAN bus, and secondly, the BCM calculates BCM handshake data (i.e. first handshake data) by using a self secret key (i.e. a first secret key) according to the random number sent by the remote control key.
In a specific embodiment, the remote control key (i.e. the target remote control key) calculates the random number generated by itself through the self-secret key (i.e. the second secret key), calculates to obtain handshake data (i.e. the second handshake data) of the remote control key, and sends the handshake data to the body controller BCM, i.e. the device for executing the dual authentication matching method of the remote control key.

and the control platform queries the serial number through the serial number matching summary table according to the second request data, and obtains true and false data.
In another specific embodiment, when the true-false data is "false" serial number data, then the matching fails;
when the true and false data is the serial number data of true, and the first handshake data and the second handshake data are inconsistent, the matching is failed;
and when the true and false data is the serial number data of true, and the first handshake data and the second handshake data are consistent, matching is successful.
In a specific embodiment, the body controller BCM (i.e. the device performing the dual authentication matching method of the key fob) performs data transmission with the control platform via the on-board communication device (TBOX).
In a specific embodiment, after receiving a remote control key serial number inquiry request sent by a car body controller BCM (i.e. a device for executing a dual authentication matching method of a remote control key), the TBOX sends the remote control key serial number inquiry request to a control platform, after receiving the remote control key serial number inquiry request, the control platform inquires whether the serial number is contained in a remote control key matching serial number table (i.e. a serial number matching table) and the remote control key is in an unmatched state, if the remote control key serial number is not contained in the remote control key matching serial number table or is in a matched state, the control platform returns that the remote control key serial number is false; if the remote control key serial number is contained in the remote control key matching serial number table and the remote control key is in a non-matching state, the control platform returns that the remote control key serial number is true. The TBOX forwards the information returned by the control platform to the body controller BCM.

In a specific embodiment, after receiving the authenticity checking result of the remote key serial number forwarded by the TBOX and the key handshake data sent by the remote key, the body controller BCM drives the steering lamp to flash three times if the remote key serial number is false, so as to prompt the user that the key matching fails; if the remote key serial number is true, whether the handshake data (namely first data) of the vehicle body controller BCM is consistent with the remote key handshake data (namely second data) is judged, if so, the remote key is successfully matched, the vehicle body controller BCM stores a new remote key serial number, erases the original remote key serial number, sends the matched data to the TBOX through a CAN bus message, and then the TBOX forwards the data to a control platform, and the control platform updates the total table of the remote key matched serial numbers and drives a steering lamp to flash twice to prompt the user that the key is successfully matched. If the handshake data of the body controller BCM is inconsistent with the handshake data of the remote control key, the remote control key is failed to match, the body controller BCM drives the steering lamp to flash for three times, and prompts the user that the key is failed to match.
In one embodiment, the control platform periodically updates a key fob matching serial number table (serial number matching table) containing all key fob that have been matched for use and key fob (e.g., after-market spare part) serial numbers that have been reserved (but not used), usage status, and BCM serial numbers that have been matched, as shown in table 1 below:
TABLE 1
Each remote control key serial number is unique, and the 'matched' indicates that the remote control key is successfully matched with the BCM and is in a use state; "unmatched" means that the key fob has been produced, but has not been used in a matched manner with the BCM, and is in stock; each body controller BCM serial number is unique.

step 305: after receiving the random number and the serial number sent by the remote control key, the BCM sends a serial number authenticity inquiry request, and calculates by using the self secret key and the random number sent by the remote control key to obtain BCM handshake data;
step 306: the TBOX forwards a request for inquiring the authenticity of the serial number of the remote control key sent by the BCM to the control platform;
step 307: after receiving a remote key serial number inquiry request forwarded by TBOX, the control platform starts to check the serial number state;
step 308: judging the new remote key serial number: whether the remote control key is contained in the total table of the matching serial numbers of the remote control key and the remote control key is in an unmatched state; when the new key fob serial number is included in the key fob matching serial number summary table and the key fob is in a non-matching state, then step 309 is entered; step 310 is entered when the new key fob serial number is not included in the key fob matching serial number summary table, or the new key fob serial number is included in the key fob matching serial number summary table and the key fob is in a matching state;
step 309: the control platform returns the remote control key serial number to be true;
step 310: the control platform returns the remote key serial number as follows: "false";
step 311: the control platform forwards the query result returned by the control platform through the TBOX according to the judgment result in the step 309 or 310;
step 312: after receiving the query result forwarded by the TBOX, the BCM judges according to the authenticity of the serial number: when the serial number query result is false, go to step 315; when the serial number query result is true, go to step 313;
step 313: the BCM compares and judges the handshake data sent by the received remote key (step 304) with the handshake data calculated by the BCM (step 305): when the two handshake data are identical, step 314 is entered; when the two handshake data are inconsistent, go to step 315;
step 314: the remote control key is successfully matched, the BCM stores a new remote control key serial number, erases an original remote control key serial number, transmits the matched data to a TBOX through a CAN total message, and the TBOX forwards a control platform;
