According to one embodiment, an information processing apparatus includes a processor, a main memory, and a memory controller. The memory controller executes an access restriction for each memory region. A first program decodes a protected program which was encrypted in a secure mode. The first program places the protected program which was decoded in a memory region. A second program executes the protected program in a secure mode. The processor places a code region and a protected data region in the protected program which was decoded in a memory region having an access restriction by using the first program. When an access to the protected data region is confirmed, the processor confirms by using the second program that the access is caused by a command from the code region placed by the first program, and then, executes the command. |
