Hi,
Inam targeting the asic aes coprocessor that comes with stm32f4 target with cw308 and husky. Initially that attack is not successful with 10000 traces. Is is possible to attack this target with husky at all?
Yes this target is possible to attack with Husky. What leakage model are you using for the attack?
I am targeting the hardware aes engine and using HD leakage model. The SNR is like 0.2. how many traces should I collect?
Do mean correlation, or SNR? That crypto engine is vulnerable to an attack of the Hamming distance between the input and output of the last round.
Ok!! I am trying to attack from the first round. Can it be broken from first round too? Any chance?
No, an attack from the first round won’t work due to the presence of MixColumns
