  "textContent": "A vehicle secure start method applicable to an electronic control unit of a vehicle includes, after the vehicle is powered on, signing stored first firmware based on a preset symmetric encryption algorithm and a symmetric key to obtain a first signature value, comparing the first signature value with a stored second signature value, and controlling the vehicle to be securely started in response to the first signature value being same as the second signature value. The symmetric key is generated based on a random number generation algorithm when firmware is received for a first time. The second signature value is generated by performing encryption based on the preset symmetric encryption algorithm and the symmetric key when the first firmware is received.",
