Abstract
An information processing apparatus includes a nonvolatile memory, a flag settable to a first value indicating that a program stored in a memory region of the nonvolatile memory has not been verified, and to a second value indicating that the program has been verified, a switching circuit configured to set the flag to the first value, in response to a request for permission to modify the program stored in the memory region, and a verification circuit that sets the flag to the second value upon verification of the program stored in the memory region, and upon restart of the information processing apparatus, carries out a verification process of the program prior to execution of the program if the first value is set in the flag, and executes the program without the verification process if the second value is set in the flag.
