摘要
A system receives, at a runtime library executed within a trusted execution environment (TEE) of a host system, a request from an application to invoke a predetermined function to perform a predefined operation. In response to the request, the system identifies a kernel object associated with the predetermined function. The system verifies an executable image of the kernel object using a public key corresponding to a private key that was used to sign the executable image of the kernel object. In response to successfully the system verifies the executable image of the kernel object, transmitting the verified executable image of the kernel object to a data processing (DP) accelerator over a bus to be executed by the DP accelerator to perform the predefined operation.
