Abstract

The invention discloses a trusted application (TA) interactive method and apparatus. The method includes that a first TA in a trusted execution environment (TEE) generates first application interactive data on a second TA in the TEE while executing a data processing request; the first TA stops running after sending an application running request on the second TA to a rich execution environment (REE); the second TA runs after receiving the application running request, forwarded by the REE, on the second TA; and the second TA acquires the first application interactive data and generates result data on the second TA according to the acquired first application interactive data. The invention is used for solving the problem of there being security risks in a TEE system due to frequent process switching in the TEE using an interactive method between TAs in the prior art.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for secure application TA interaction. Background technique [0002] The development of mobile communication technology has brought about the rapid development of mobile terminal technology. Modern mobile terminal equipment provides a powerful and flexible REE (Rich Execution Environment, common execution environment), but it also makes the equipment vulnerable to security threats. TEE (Trusted Execution Environment, Trusted Execution Environment) is a technical solution proposed to solve the security risks existing in current mobile terminal equipment. TEE and REE run in parallel on the same device. TEE can guarantee the storage, processing and protection of sensitive data in a trusted environment, and provides a secure execution environment for authorized security software (trusted software). Protection, confidentiality, integrity and data access rights en...
