摘要： PROBLEM TO BE SOLVED: To evaluate functions of an information processing apparatus in different execution environments.
SOLUTION: In a method for evaluating functions of an information processing apparatus in different execution environments, a dependence calculation part 12 uses dependence evaluation indices stored in a dependence evaluation index DB 22 to calculate the dependence of functions to be evaluated out of various functions on the use scene and status in which an information processing apparatus is used and on each start status of the information processing apparatus. An influence calculation part 11 then uses influence evaluation indices stored in an influence evaluation index DB 21 to calculate the influence of the use scene and status and the start status on the execution of each function to be evaluated. A comparison part 14 compares the dependence and influence calculated for the same function to be evaluated. A determination part 15 then determines whether or not the execution of the function to be evaluated is impaired by the use scene and status and the start status according to the comparison.

摘要： PROBLEM TO BE SOLVED: To provide a tamper-proof exponentiation operation method wherein an exponentiation operation method of Brickell etc. is provided with resistance to side channel analysis.
SOLUTION: An exponentiation operation method having resistance to side channel analysis is provided. The exponentiation operation often used in encryption algorithm frequently becomes a target of side channel analysis, and is required to have resistance to it. In this method, the exponent parts are rearranged prior to the operation so that the operation columns become constant when exponentiation operation is performed. Thus, the exponents as secret information can be prevented from being estimated from power consumption waveforms or processing time.
