Wibubox 13

[johnvb]

Hi everybody I have wibubox 13 dongle
The dump show processing 0 entry only
Have 2 pairs
1 solved used with gkfeal and get valid information
2 need table emulation
But question how we know the program need to solve second pair? or first pair is enough for emulator??

first pair is feal8 with 40-bit key. we can to get PlainL and PlainR key from cipher, possible to solve
second pair is feal32 64-bit key. we can to get PlainL and PlainR key from cipher, but not possible to solve - need huge time on GPU also

Ok understand you
The kit missing feal 32 tool that's get plain R an L. From second pair
Anyone have this tool?
We can exchange?

this pair useless. not possible to solve.

@bfox I'm wondering . If second pair crypt not possible to solve and need table emulation how to do this?

[BfoX]

@Cobrix: yes, table only. as i says before can solve feal with 8 round and 40 bit key (2 hour on my GTX 1050Ti). not possible feal with 32 round and 64 bit key.

table only == you mean query and response
or usb trace log ??

[BfoX]

sure, query and response

there is a way with a good GPU and optimized algo to solve feal32 using differential cryptanalysis in around 5-10 days

have any success samples for feal32 and GPU? we can compare this key for the demo wibu-key dongle if you want/can

sure... pm youre email
