<P>PROBLEM TO BE SOLVED: To improve resistance evaluation accuracy by separating a signal source related to confidential information from the other signal sources which become noise. <P>SOLUTION: A side channel information measuring portion 2 measures side channel information which leaks from an encryption device 1 of an evaluation target. A passing band deciding portion 4 decides a passing band of a quefrency window. A cepstrum analyzing portion 3 executes cepstrum analysis on tha basis of the passing band of the quefrency window, to the side channel information measured by the side channel information measuring portion 2. A DSCA resistance evaluating portion 5 determines the pros and cons of resistance to a side channel attack of the encryption device 1 of the evaluation target, on the basis of the side channel information analyzed by the cepstrum analyzing portion 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
