Abstract
The present disclosure provides a TEE initialization method. An operator identifier acquired from an SIM card is compared with operator identifiers in a list or a table of correspondence between the operator identifiers and public keys preset in a TEE of a mobile terminal, so as to acquire a public key and authenticate a TSM platform with the public key. After the TSM platform has been authenticated successfully, loading processing on the TEE is completed, and a management key of the TEE is downloaded from the TSM platform. According to the present disclosure, it is able to initialize the TEE of the mobile terminal without designating an operator, thereby to improve the openness of the mobile terminal as well as the user experience.
