Re: key diversification Mifare 1k hotel

Well..
Sector 1 key algo..

UID              KeyA
D 3 E4 B9AC  0002 92 C BD8A2
3 3 C9 E6AC  00B6 30 C D4B92
4 3 E0 4DAD  2004 92 C BBF9A
B 3 B4 B0AC  00A2 96 C DE822
6 3 85 B0AC  00A2 B4 C 90EA2
5 3 8E B0AC  00A2 04 C B3AA2
C 3 81 EDAC  0006 B4 C BFD92
A 3 7D B1AC  0082 32 C D3C62
0 3 DA 51AD  2084 00 C FDF2A
8 3 CE 53AD  2094 00 C F4CAA
0 3 3A 55AD  2084 06 C F3F4A
D 3 A8 AFAC  0012 16 C B8992
8 3 53 CFAD  2014 A0 C F4D52
6 3 83 4EAD  2034 A4 C 9FF9A
7 3 B5 4EAD  2034 B6 C 9DA1A
7 3 0A 4EAD  2034 04 C 96BDA

The last two UID bytes is very related to the two first bytes in KEY A.
UID[3] = KEY[0]
UID[2] = KEY[1]

and there is a 'C' in all,   if xor-relating,  means its xor:ed with a 0,   or  the matching all 3  colum in uid...
