Abstract

The invention discloses a vehicle unlocking method and system, and the method comprises the steps: enabling a mobile terminal and a vehicle-mounted terminal to initialize a current interaction secretkey K0 in advance, and respectively storing the values of K0 locally, and obtaining K0m and K0c; the unlocking method comprises the steps that after the mobile terminal determines an unlocking demand,a next interaction key K1 is generated; the mobile terminal generates an unlocking request message and sends the unlocking request message to the vehicle-mounted terminal, and the unlocking request message at least carries a result of encrypting K1 with K0m; after receiving the unlocking request message, the vehicle-mounted terminal decrypts the request message by using locally stored K0c; if thedecryption is successful, the vehicle is unlocked, and the locally stored K0c value is updated by using the decrypted result; and after the mobile terminal determines that the vehicle is successfullyunlocked, the locally stored K0m value is updated by using the locally generated K1.

Description

technical field [0001] This specification relates to the technical field of data security, in particular to a method and system for unlocking a vehicle. Background technique [0002] With the development of the Internet of Vehicles, the technology of using mobile terminals to control vehicles has made some progress. For example, it has been realized to control the unlocking and starting of vehicles through mobile terminals, thereby reducing people's dependence on physical keys. [0003] At present, the method of controlling vehicle unlocking based on the mobile terminal is as follows: the mobile terminal and the vehicle-mounted terminal in the vehicle store a fixed key, and the vehicle-mounted terminal decrypts the encrypted unlocking command sent by the mobile terminal based on the fixed key. The vehicle is then unlocked. If the fixed key is sniffed by the thief through the network, the thief can unlock the vehicle based on the sniffed fixed key. It can be seen that in th...
