Abstract:
According to an embodiment, an information processing device includes a monitoring circuit, a non-secure processing circuit, a secure processing circuit, memory access control circuit. The monitoring circuit switches mode between a non-secure mode and a secure mode. The non-secure processing circuit runs in the non-secure mode, and reads communication data from and writes communication data in a shared memory. The secure processing circuit runs in the secure mode, and reads the communication data from the shared memory and writes the communication data in a storage. The memory access control circuit manages access from the non-secure processing circuit and the secure processing circuit based on a memory access control table in which physical addresses in the shared memory are associated with state information either indicating a locked state for not allowing writing but allowing reading by the non-secure processing circuit or indicating an unlocked state attained by cancelling the locked state.

Claim (Index 16):
An information processing method comprising:\n Switching, by a monitoring unit, mode between a non-secure mode and a secure mode; reading-writing, by a non-secure processing unit, that includes running in the non-secure mode, and reading communication data from and writing communication data in a shared memory; writing, by a secure processing unit, that includes running in the secure mode, and reading the communication data from the shared memory and writing the communication data in a storage; and managing, by a memory access control unit, access from the non-secure processing unit and the secure processing unit based on a memory access control table in which physical addresses in the shared memory are associated with state information either indicating a locked state for not allowing writing but allowing reading by the non-secure processing unit or indicating an unlocked state attained by cancelling the locked state.
