Abstract

The present invention discloses an interaction method of a TA (Trusted Application) and an SE (Secure Element), a TA (Trusted Application), an SE (Secure Element) and a TSM (Trusted Service Manager) platform and belongs to the communication technical field. The objective of the invention is to improve security in the processing process of a whole-terminal SIM shield. The interaction method includes the following steps that: the TA compiles sensitive data stored in a TEE (Trusted Execution Environment) into a first APDU (Application Protocol Data Unit) instruction; the SE analyzes the received first APDU instruction; the SE processes the sensitive data obtained through analysis; the SE encrypts the processed sensitive data; the SE compiles the encrypted sensitive data into a second APDU instruction; the TA analyzes the received second APDU instruction; and the TSM platform analyzes the received encrypted sensitive data. The interaction method of the TA and the SE, the TA, the SE and the TSM (Trusted Service Manager) platform of the invention are used for the processing of the all-terminal SIM shield.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an interaction method between TA and SE, TA, SE and TSM platform. Background technique [0002] The development of mobile communication technology has brought about the rapid development of mobile terminal technology. The mobile terminal equipment in the prior art provides a powerful and flexible REE (Rich Execution Environment, Rich Execution Environment), but it also makes the mobile terminal equipment vulnerable to security For this reason, a technical solution of TEE (Trusted Execution Environment, Trusted Execution Environment) is proposed. Specifically, TEE can guarantee the storage, processing and protection of sensitive data in a trusted environment, and provides a secure execution environment for TA (Trusted Application, trusted application). [0003] At present, in the process of processing the all-terminal SIM shield, it is generally realized through da...
