Information processing apparatus and method of controlling the apparatus

A method of controlling an information processing apparatus holding a secure chip in which a hash value is capable of being registered, the method comprising:

• determining whether the information processing apparatus returns from an idle state;
• detecting, if the determining determines that the information processing apparatus returns from the idle state, initialization of the secure chip before starting application software;
• and
• if detection of the initialization of the secure chip is done and restart of the information processing apparatus is not permitted, registering a constant indicating that a platform configuration register (PCR) has an initial value in system return in the secure chip, and if determination that the information processing apparatus returns from an idle state is not done, controlling an operation of the information processing apparatus so that the hash value of the application software is registered in the secure chip.

A non-transitory storage medium storing a program that when executed causes an information processing apparatus to perform a process, the information processing apparatus holding a secure chip in which a hash value is capable of being registered, the process comprising:

• determining whether the information processing apparatus returns from an idle state;
• detecting, if the determining determines that the information processing apparatus returns from the idle state, initialization of the secure chip before starting application software;
• and
• if detection of the initialization of the secure chip is done and restart of the information processing apparatus is not permitted, registering a constant indicating that a platform configuration register (PCR) has an initial value in system return in the secure chip, and if determination that the information processing apparatus returns from an idle state is not done, controlling an operation of the information processing apparatus so that the hash value of the application software is registered in the secure chip.
