Abstract
Provided is a security protection method for a heterogeneous system, wherein the heterogeneous system includes a processor. The processor includes a first region, wherein the first region includes a physical unclonable function circuit. The method includes: detecting whether an input of the heterogeneous system is abnormal; acquiring a configuration file in response to the input of the heterogeneous system being detected as abnormal, wherein the acquired configuration file is different from a configuration file of the physical unclonable function circuit that has run; and reconstructing, on the processor, a mapping of the physical unclonable function circuit based on the acquired configuration file.
