Abstract:
The instruction code including an instruction code stored in the area where the encrypted instruction code is stored in a non-rewritable format is authenticated using a specific key which is specific to the core where the instruction code is executed or an authenticated key by a specific key to perform an encryption processing for the input and output data between the core and the outside.

Claim (Index 1):
A processor configured to operate in a first mode in which an access to a secure address space is permitted or in a second mode in which an access to the secure address space is prohibited, the processor comprising:\n an execution unit configured to output a first virtual address; and a memory access control unit configured to access a first physical address corresponding to the first virtual address by referring to a flag of a page table entry in a translation look-aside buffer, wherein, only in the first mode, the memory access control unit permits an access to the first physical address within the secure address space in which the flag of the page table entry is set to a value indicating that a corresponding address space is secure, and wherein, by executing a first instruction code stored in the secure address space in the first mode, a second instruction code is checked in the first mode before the second instruction code is executed in the second mode.
