Abstract

An information processing apparatus includes a verification unit configured to verify, using a method starting with hardware verification at a time of startup of a system, partial software which is divided into a plurality of parts and gradually started up, a second verification unit configured to verify another partial software based on the verified partial software, and a third verification unit configured to verify software to be executed at an arbitrary timing prior to execution of the software. In a case where the third verification unit is in operation at a time of update of the partial software, the operation of the third verification unit is stopped, and restart is performed after completion of the update, so that a sequence of verification processes starting with the hardware verification up to a result of verification at a time of execution is applied.
