Security processing method for car sharing service

A security processing method for a car sharing service, comprising:

• encrypting, by a smart terminal, a second random code according to a first smart terminal encryption key, to obtain a first cyphertext, the first smart terminal encryption key comprising a first random code and order form information sent by a cloud server;
• receiving, by the smart terminal, a third random code sent by a vehicle, the third random code being obtained by the vehicle by decrypting the first cyphertext according to a first vehicle encryption key, the first vehicle encryption key comprising the first random code and the order form information sent by the cloud server;
• subjecting, by the smart terminal, the second random code and the third random code to comparative verification, to obtain an identity authentication result;
• sending, by the smart terminal sending, in the event the identity authentication result has passed, encrypted service data to the vehicle;
• and
• decrypting, by the vehicle, the service data to execute the service data.
