Abstract
A computer-implemented method, non-transitory, computer-readable medium, and computer-implemented system are provided for data transmission in a trusted execution environment (TEE) system. The method can be executed by a thread on a TEE side of the TEE system. The method includes obtaining first data; calling a predetermined function using the first data as an input parameter to switch to a non-TEE side; obtaining a write offset address by reading a first address; obtaining a read offset address by reading a second address; determining whether a quantity of bytes of the first data is less than or equal to a quantity of writable bytes; if so, writing the first data into third addresses starting from the write offset address; updating the write offset address in the first address; and returning to the TEE side.
