Abstract
According to an embodiment, an information processing apparatus includes a first storage unit, a second storage unit, a power supply state control unit, a cryptographic key movement unit, a communications unit, an information input determination unit, a communications state determination unit, and a cryptographic key control unit. The cryptographic key movement unit is configured to move at least part of the cryptographic key data stored in the first storage unit to the second storage unit before a shift from a power-on state to another power supply state. In the other power supply state, the cryptographic key control unit returns the cryptographic key data from the second storage unit to the first storage unit if it is determined that there is an input of information which matches the information stored in the second storage unit and it is determined that communications are enabled between the communications unit and a base-station apparatus.
