Side-Channel Attacks (SCA) extract cryptographic keys from hardware systems by analyzing power traces or electromagnetic emission data from the target device along with the corresponding collection of plain and/or cipher data. The traditional approach of dealing with SCA by measuring device parameters after manufacturing is expensive and time-consuming.

Fault Injection Attacks (FIA) extract secrets, e.g. cryptographic keys, from hardware systems by injecting faults, e.g. using a laser beam to disrupt the circuit function, or increasing operating frequency or supply voltage beyond their maximum specifications.

Fortify’s AES security evaluation by SGS

“Summary. The leakage analysis (Welch t-test) on over 30 million traces did not show statistically significant first- and second-order differences between trace sets with fixed and random inputs. The template-based DPA analysis, on the pseudo-random trace set for the profiling phase (15 million traces) and on a sub-set of 300k fix input traces for matching phase targeting the first-round S-box output, and template attack on ciphertext, did not indicate any potential information leakage.”

” The results for the soft IP presented in the report were obtained on the TOE which is the basic hardware implementation of the soft IP without additional levels of security (e.g. that are present in a secure silicon layout). Therefore the internal strength of the soft IP itself was evaluated. This indicates that the investigated features and parameters of the soft IP implementation should be robust against SCA and fault injection attacks in different implementations including ASIC. Nevertheless, according to the Common Criteria rules, the strength of the final composite product must be evaluated on its own.”
