Resistance evaluation for differential power analysis (DPA) and differential electromagnetic analysis (DEMA) kinds of side channel attack (SCA) methods to cryptographic ICs, costs a lot.
The reason is that at least 10 side-channel (SC) waveforms should be averaged for each plain text.
The resistance evaluation needs considerable number of plain texts, so reduction of averaging number can make a large impact on evaluation cost. This work proposed a method to reduce the averaging number by using an LC resonator.
The proposed method utilizes antiresonance of LC parallel circuit that inserted to the power distribution network of cryptographic FPGA.
It increases transfer impedance for the side-channel trace from the FPGA to the measurement port, which improves signal to noise ratio of the trace.
This SNR improvement reduces the number of averaging. The proposed method
was validated as follows. First, correlation power analysis (CPA) was performed as a representative DPA method.
Next, LC resonator was designed to resonate around the frequency band where the SC information leaked intensely.
Finally, CPA was performed again after inserting LC resonator.
Results showed that the proposed method decreased the number of averaging, providing the same level of correlation coefficients obtained before inserting LC resonator.
Before insertion of the LC resonator, correlation coefficient was 0.49 when 10 traces were averaged.
However, comparable correlation 0.53 was obtained by inserting the LC resonator with averaging of only 3 traces.
It was indicated that the proposed method could accelerate the evaluation for DPA/DEMA. |
