    • A mobile telephone includes a CPU that obtains and decodes instructions included in an OS, a nonsecure program, a switch device driver, and a secure program, and operates according to the decoding results. A memory includes a controlled area and an uncontrollable area. The OS has only the controlled area as its access space, and includes an instruction for mediating access of the nonsecure program to the controlled area and an instruction for instructing the switch device driver to make a switch to the secure program. The nonsecure program includes an instruction to access the controlled area via the OS. The switch device driver includes an instruction to make a switch from execution of the OS to execution of the secure program in response to an instruction of the OS. The secure program has only the uncontrollable area as its access space, and includes an instruction to access the uncontrollable area.
    • 移动电话包括获取并解码包括在OS中的指令,非安全程序,开关设备驱动程序和安全程序的CPU,并且根据解码结果进行操作。 存储器包括受控区域和不可控区域。 OS仅具有受控区域作为其访问空间,并且包括用于调停非安全程序到受控区域的访问的指令以及用于指示交换机设备驱动程序切换到安全程序的指令。 非安全程序包括通过操作系统访问受控区域的指令。 开关设备驱动器包括响应于OS的指令从OS的执行切换到安全程序的执行的指令。 安全程序只有不可控制的区域作为其访问空间,并且包括访问不可控区域的指令。

    • The information processing apparatus includes: a tampering determination unit (2501) determining whether or not the shared library in the volatile memory is tampered with; a shared library information holding unit (2504) holding shared library information including information on a correspondence relationship between the shared library and the process; a process control unit (2502), in the case where the determination shows that the shared library in the volatile memory is tampered with, (i) specifying the process which uses the shared library in the volatile memory with reference to the shared library information and (ii) stopping the specified process; and a shared library recovering unit (2505), in the case where the determination shows that the shared library in the volatile memory is tampered with, reloading the shared library in the non-volatile memory into the volatile memory so as to recover the shared library in the volatile memory.
    • 信息处理装置包括:篡改确定单元(2501),确定易失性存储器中的共享库是否被篡改; 共享库信息保持单元,保存共享库信息,包括关于共享库与处理之间的对应关系的信息; 处理控制单元(2502),其中所述确定表明易失性存储器中的共享库被篡改,(i)参考共享库信息指定使用易失性存储器中的共享库的处理,以及 (ii)停止指定​​的过程; 和共享库恢复单元(2505),在确定显示易失性存储器中的共享库被篡改的情况下,将非易失性存储器中的共享库重新加载到易失性存储器中,以便恢复共享库 在易失性存储器中。
