Design and application of CPA research platform for ASIC

Differential Power Analysis(DPA),a technology of non-invasive side-channel attack,has posed a serious threat for the safety of cipher integrated circuits.In order to evaluate the effectiveness of power analysis attack countermeasure conveniently,following the gate-level power analysis method,a Correlation Power Analysis(CPA)research platform based on PrimeTime PX and MATLAB is built.The auxiliary platform has a strong universality,and only by reworking cipher-specific power model,the algorithm level countermeasures for different ciphers can be evaluated easily.As an application,standard AES algorithm and the improved AES algorithm with threshold countermeasure method is attacked,showing the platform effectiveness.
