and connects with the vehicle CAN bus to receive and send data flow.
6.13 Program upgrade
The vehicle terminal supports local program upgrade and OTA remote upgrade.
6.14 Security policy
The vehicle terminal provides technically feasible safety strategies to ensure that
various performances and functions of the product are within the safe range. It can be
realized from the following aspects:
The data stored and transmitted by the vehicle terminal is encrypted, and the
asymmetric encryption algorithm is adopted. The national secret SM2 algorithm or
RSA algorithm can be used, and the private key is strictly protected by hardware;
— The data stored and transmitted by the vehicle terminal is complete;
Scan the data during data transmission to find malicious data and attacks in
time, such as writing commands to CAN bus devices such as ECU or other
instructions beyond normal data reading. More than 95% of attacks are detected in
security detection, and the false positive rate is less than 1%. Find and start protective
measures within 10s after the attack;
Without the consent of the enterprise, the terminal can only read the vehicle
data and cannot send any instructions other than the diagnosis request to the ECU;
The vehicle terminal only sends data to the outside and does not accept
operation instructions other than the manufacturer.
6.15 Anti-dismantling technology
The vehicle terminal has anti-dismantling technical measures to ensure that the
terminal will not be removed maliciously. The anti-dismantling technology of vehicle
terminal and mechanical connection includes two ways:
1Real time detection of anti-dismantling wire connection status;
