Faulting multiple times the tables requires many disk writes so we'll do it in a tmpfs.
All steps are performed by mount_tmp_and_attack.sh
:
mkdir -p tmp
mount|grep -q $(pwd)/tmp || sudo mount -t tmpfs -o mode=01777,size=20m tmpfs tmp
cp attack_owb_chow.py ../../deadpool_dfa.py ../../../JeanGrey/phoenixAES.py tmp
cp ../target/encryptECB tmp
cp ../target/key.txt tmp/key.txt.gold
cd tmp
./attack_owb_chow.py
Adapt it to your setup if needed. It requires deadpool_dfa.py
from this repository and phoenixAES.py
from JeanGrey repository.
Result is the last round key, so to roll back key scheduling up to initial AES key, one can e.g. use aes_keyschedule
from Stark project.
