Thanks @Alex_Dewar, after connecting cable I was able to get right key. But " Windowing Peaks" code is giving me one bit error (one bit of key is incorrect). Kindly guide me to resolve this issue as well.
Code:
Add your code here
from tqdm.notebook import trange
import numpy as np
#Store your key_guess here, compare to known_key
key_guess = []
known_key = [0x2b, 0x7e, 0x15, 0x16, 0x28, 0xae, 0xd2, 0xa6, 0xab, 0xf7, 0x15, 0x88, 0x09, 0xcf, 0x4f, 0x3c]
#Which bit to target
bitnum = 0
full_diffs_list = []
for subkey in trange(0, 16, desc=“Attacking Subkey”):
max_diffs = [0]*256
full_diffs = [0]*256
for guess in range(0, 256):
full_diff_trace = calculate_diffs(guess, subkey, bitnum)
full_diff_trace = full_diff_trace[(1010 + subkey*60):]
max_diffs[guess] = np.max(full_diff_trace)
full_diffs[guess] = full_diff_trace
#Make copy of the list
full_diffs_list.append(full_diffs[:])
#Get argument sort, as each index is the actual key guess.
sorted_args = np.argsort(max_diffs)[::-1]
#Keep most likely
key_guess.append(sorted_args[0])
#Print results
print("Subkey %2d - most likely %02X (actual %02X)"%(subkey, key_guess[subkey], known_key[subkey]))
#Print other top guesses
print(" Top 5 guesses: ")
for i in range(0, 5):
g = sorted_args[i]
print(" %02X - Diff = %f"%(g, max_diffs[g]))
print("\n")
Output:
A Jupyter widget could not be displayed because the widget state could not be found. This could happen if the kernel storing the widget is no longer available, or if the widget state was not saved in the notebook. You may be able to create the widget by running the appropriate cells.
