<p>A secure protection method executed by a processor is provided. The secure protection method includes the following steps. Perform a security checking before or after executing an instruction according to an instruction security attribute (ISA) of the instruction and a security attribute (SA) of an operational event (OE). Ignore the OE, defer the OE, or raise a security exception when the security checking fails. The OE is generated as a side effect when the processor fetches or executes the instruction, or generated as a monitoring result on the instruction, or generated in response to an external input of the processor.</p> |
