Abstract: A security processing method for a car sharing service includes: a smart terminal encrypting a second random code according to a first smart terminal encryption key, to obtain a first cyphertext, the first smart terminal encryption key having a first random code and order form information from a cloud server; the smart terminal receiving a third random code from a vehicle, the vehicle obtaining the third random code by decrypting the first cyphertext according to a first vehicle encryption key that includes the first random code and the order form information sent by the cloud server; the smart terminal subjecting the second random code and the third random code to comparative verification, to obtain an identity authentication result; the smart terminal sending, if the identity authentication result has passed, encrypted service data to the vehicle; and the vehicle decrypting the service data to execute the service data.

Abstract: An association method includes identifying candidate file sets from a plurality of application files. Content indicative of each of the candidate file sets is presented. An application is associated with application files of one of the candidate file sets according to a detected selection of the content indicative of that candidate file set.
