This file implements an example authentication algorithm defined for 3GPP

EAP-AKA to be tested properly with real USIM cards.
This implementations assumes that the r1..r5 and c1..c5 constants defined in
TS 35.206 are used, i.e., r1=64, r2=0, r3=32, r4=64, r5=96, c1=00..00,
c2=00..01, c3=00..02, c4=00..04, c5=00..08. The block cipher is assumed to
be AES (Rijndael).
