The BS transmits RAND and AUTN to the UE and the latter employs the same hash methods to generate authentication responses XMAC and RES, and then compares whether MAC is same with XMAC.
Different from AKA where AUTN is transmitted directly to the UE, the BS separates the authentication code MAC out and uses a fault-tolerant hash method hash([??]) proposed in our previous work  to bind MAC and [H.sub.10](f) to generate physical layer response mac in (3),
Then the BS sends AUTN':= SQN[symmetry]AK || AMF, the random number RAND and the physical layer response mac to the UE.
Upon receipt of a (RAND, AUTN
), the USIM computes the anonymity key AK = [f.sub.5]k (RAND) and retrieves the unconcealed sequence number SQN = (SQN [direct sum] AK) [direct sum] AK, XMAC-A = [f.sub.1]k (SQN [parallel] RAND [parallel] AMF), the response RES = [f.sub.2]k (RAND), the cipher key CK = [f.sub.3]k (RAND) and the integrity key IK = f4k (RAND) as shown in fig.2.
