I am looking to get P-box and S-box from firmware
Decided to search the firmware for
Pbox - 8 nibbles from 0-7
i.e
pbox = [2, 0, 6, 5, 7, 4, 3, 1]
Found it :)
And for S-Box
16 bytes from 0-15 (based on my research on S-box)
i.e
sbox = [5, 11, 7, 12, 4, 8, 0, 3, 13, 9, 6, 1, 2, 14, 10, 15]
However cannot find it in firmware.
They should be next to each other in firmware.
But they're not.
Question:
Are my assumptions about pbox values and Sbox values correct? i.e values from 0-7 for pbox and 0-16 for sbox?
