PROCESSING APPARATUS, EMBEDDED SYSTEM, SYSTEM-ON-CHIP, AND SECURITY CONTROL METHOD

Abstract:

A processing apparatus, an embedded system, a system-on-chip, and a security control method are disclosed. The processing apparatus includes a processor, adapted to execute a program; and a memory, coupled to the processor and adapted to provide a plurality of enclaves isolated from each other. One of the plurality of enclaves is a source enclave, another one of the plurality of enclaves is a target enclave, and the source enclave and the target enclave each are used to provide a storage space required for running a corresponding program. The processing apparatus further comprises a storage access controller, adapted to transmit specified data stored in the source enclave to the target enclave. According to the processing apparatus, the embedded system, the system-on-chip, and the security control method provided in the embodiments of the present disclosure, a storage access controller can be used to implement a data transmission process from a source enclave to a target enclave, without requiring a processor for data transferring, thereby improving efficiency of inter-enclave data transmission while ensuring security.
