1. An information processing apparatus having a configurable security measure, comprising:
- a sensor configured to sense at least one of a voltage, a clock frequency, temperature, and light supplied to the information processing apparatus;
one or more processors connected to the sensor, wherein the one or more processors are operable to;
determine an attack on the information processing apparatus based on the at least one of the voltage, the clock frequency, the temperature, and the light sensed by the sensor; and
strengthen the security measure in an event the attack is determined.

Abstract
An information processing apparatus including: an attack detection unit that detects an attack; and a strength adjustment unit that incrementally raises the strength of a security measure every time that an attack is detected by the attack detection unit.

11. A method for configuring a security measure of an information processing apparatus, comprising:
-
sensing, by a sensor, at least one of a voltage, a clock frequency, temperature, and light supplied to the information processing apparatus; determining, by one or more processors, an attack on the information processing apparatus based on the at least one of the voltage, the clock frequency, the temperature and the light sensed by the sensor; and strengthening, by the one or more processors, the security measure of the information processing apparatus in an event the attack is determined.

12. A method for configuring a security measure of an information processing apparatus, comprising:
-
determining, by one or more processors, an attack on the information processing apparatus in an event a predetermined verification process fails, wherein the predetermined verification process includes comparing calculation results obtained by performing a same calculation at least twice; and strengthening, by the one or more processors, the security measure of the information processing apparatus in an event the attack is determined. - View Dependent Claims (13)
