Description
Technical Field
The invention is used in the technical field of vehicle access systems, and particularly relates to a method for starting a vehicle without a key.
Background
With the development of mobile network technology, the proportion of vehicle-mounted mobile communication terminals configured on vehicles is higher and higher, so that the functions of controlling vehicles through mobile terminals gradually become a trend, such as functions of remote vehicle condition query, remote vehicle control for starting air conditioners, remote vehicle searching, unlocking and the like. The cloud platform serves as a bridge for the mutual communication between the vehicle-mounted mobile communication terminal and the mobile communication terminal, not only plays a role in establishing a communication channel between the vehicle-mounted mobile communication terminal and the mobile communication terminal, but also needs to perform bidirectional identity authentication on the vehicle-mounted mobile communication terminal and the mobile communication terminal. The vehicle-mounted mobile communication terminal and the cloud platform are developed and realized by a whole vehicle factory, the whole vehicle factory can preset a security certificate in the vehicle-mounted mobile communication terminal to perform bidirectional identity authentication with the cloud platform and establish a security channel, and each vehicle of the certificate is different. However, the mobile terminal is not controlled by the whole vehicle factory, and the mobile terminal manufacturers are various, and cannot preset the security certificate with the cloud platform of the whole vehicle factory in advance, so that bidirectional identity authentication cannot be directly performed.
The mobile terminal logs in the APP through inputting the account number and the password, the APP can be communicated with a cloud platform of a whole vehicle factory, the account number and the password serve as evidences authenticated by the cloud platform, and because a credible safety channel does not exist between the cloud platform and the APP, the account number and the password cannot be safely stored, the information safety risk of the account number and the password is extremely high, and most vehicles do not support the function of controlling the vehicle to start and drive under the condition without keys.
An electric vehicle starting control method (201310022551.3) based on identification password and an automobile starting system (201710309083.6) both provide a mode of presetting or setting the password in the vehicle in advance, and a method for starting the vehicle by comparing the same password input by a user. The password in the patent represents the identity of a user, and if the password is stolen by others, others can acquire the authority of a vehicle owner; secondly, there is great password leakage risk, and the password leaves the trace in the place of staying, is easily carried out long-range the cracking by the hacker. The information security method implemented in the above patent has a high risk and is prone to vehicle theft.

Detailed Description
The invention will be further explained with reference to the drawings.
As shown in fig. 4, the present invention provides a method of starting a vehicle without a key, the method comprising:
step S1: after a user sends an unlocking command through a mobile terminal or unlocks a vehicle through a mechanical key to enter the vehicle, a 'start' button carried on the vehicle is continuously pressed twice to activate a starting function, the BCM1 of the vehicle body receives an activation signal that the user continuously presses the 'start' button twice, then a random factor R1 is generated through a true random number generator or a timer, and a starting request signal carrying the generated random factor R1 is sent to the vehicle-mounted host 2.
Step S2: after receiving the start request signal sent by the vehicle body controller BCM1, the vehicle-mounted host 2 lights up the screen of the vehicle-mounted host 2, and outputs display information prompting the user to confirm activation of vehicle start through the display screen of the vehicle-mounted host 2, if the user clicks the "confirm" icon within a first set time (such as 5S, 10S, etc.), step S3 is executed, if not (i.e., the user clicks the rejection or cancel or does not operate within the first set time), the flow is ended.
Step S3: the vehicle-mounted host 2 forwards a starting request signal carrying a random factor R1 to the cloud platform 3 by using a safety channel (a channel established between a T-box terminal of a vehicle and the cloud platform) pre-established with the cloud platform 3; then, a window prompting the user to input the random factor R2 is displayed on the screen of the in-vehicle host 2.
Step S4: the cloud platform 3 generates a control instruction original text T based on a control instruction format and content predefined between the cloud platform and the vehicle body controller BCM 1; meanwhile, the cloud platform 3 encrypts the control instruction original text T and the random factor R1 by using a private key of an asymmetric encryption algorithm to generate a ciphertext E, then generates a random factor R2 based on a true random number generator, and finally performs a one-way hash algorithm on the ciphertext E by using a random factor R2 to generate a message authentication code M.
Step S5: the cloud platform 3 sends the ciphertext E and the message authentication code M to the vehicle-mounted host 2, and sends the random factor R2 to the mobile terminal 4; in step S5, the cloud platform 3 sends the random factor R2 to the mobile terminal 4 in a short message verification code manner, and for the mobile terminal 4, it is not necessary to download an APP or perform data processing, and it is only necessary to receive a short message prompt message. The private key of the asymmetric cryptographic algorithm or the symmetric key of the symmetric cryptographic algorithm does not need to be stored in the mobile terminal 4 and the vehicle end; sensitive information such as a private key of the asymmetric cryptographic algorithm and the like is stored on the cloud platform 3, so that relatively speaking, lawless persons can hardly crack the private key and the secret key stored on the cloud platform 3, and the theft prevention of vehicles is greatly facilitated.
Step S6: the vehicle-mounted host 2 waits for the user to input the random factor R2, if the vehicle-mounted host 2 receives the random factor R2 within a second set time (for example, within 10 minutes) after displaying the display window prompting the user to input the random factor R2, forwards the random factor R2, the control instruction ciphertext E and the message authentication code M to the vehicle body controller BCM1, and executes step S7, and if not, the process is ended.
Step S7: the vehicle body controller BCM1 uses R2 to perform a one-way hash algorithm on the received ciphertext E to generate a message authentication code M ', if the message authentication code M' is the same as the message authentication code M, it is determined that the integrity check of the ciphertext E passes, and step S8 is executed, if not, the process is ended.
Step S8: the BCM1 of the vehicle body controller uses a public key of an asymmetric cryptographic algorithm to check and decrypt the ciphertext E to obtain a control instruction original text T and a random factor R1 ', if the random factor R1' is the same as the random factor R1 and each parameter of the control instruction original text T meets the condition, the step S9 is executed, and if not, the flow is ended;
step S9: and the BCM1 executes the command according to the content of the control command original text T, starts the vehicle in the example and ends the process.

The vehicle-mounted host 1 is preset with a certificate before leaving a factory, and performs identity authentication and safe communication with the cloud platform 3.
In this embodiment, the cloud platform 3 is configured to, after receiving a request start signal sent by the on-board host 2, assemble a control instruction original text T, an encrypted ciphertext E, and a message authentication code M, and issue the control instruction original text T, the encrypted ciphertext E, and the message authentication code M to the on-board host 2; meanwhile, the cloud platform issues the generated random factor R2 to the mobile terminal 4. The cloud platform 3 is a root trusted platform, has the capabilities of asymmetrically encrypting, safely storing an asymmetric private key and being incapable of being acquired by other equipment, and simultaneously performs identity authentication and safe communication with the vehicle-mounted host 2.
