MAC, XRES, CK, IK are generated by hash functions specified by 3GPP with the challenge RAND and the secret key K as the inputs and their lengths are all 128 bits.
Similarly, RES is transmitted to the network to authenticate the UE by comparing RES and XRES.
During the process, authentication challenge RAND and responses (RES, XRES, MAC, XMAC) are all transmitted in plaintext.
For each n member j of group Gi For j = 1 to n [AK.sub.Gi-j] = f5([K.sub.Gi-j], [R.sub.HSS]) [CK.sub.Gi-j] = f3([K.sub.Gi-j], [R.sub.HSS]) [IK.sub.Gi-j] = f4([K.sub.Gi-j], [R.sub.HSS]) [K.sup.ASME.sub.Gi-j] = KDF(SQN [direct sum] [AK.sub.Gi-j], [CK.sub.Gi-j], [IK.sub.Gi-j], SN_ID) [XRES.sub.Gi-j]] = f6([K.sub.Gi-j], [R.sub.HSS]) End For The HSS compiles the authentication information together with the computed [K.sub.ASME] and XRES for all members of the group in the form of a table called Group Key Index (GKI).
The HSS verifies this aggregate MAC and generates a random challenge and forwards it to the MME in the form of an authentication token ([AUTH.sub.HSS]) along with the expected response (XRES) for each MTCD in the group.
SCSCF receives request IF method == "HANDOVER" IF RES == XRES & integrity-protected == true then IPaddress = Contact; P-CSCFHPaddress = Path; IF P-CSCFold != P-CSCFnew then Route "HANDOVER" to P-CSCFnew ENDIF ELSEIF method == "REGISTER" IF RES != XRES then Create User-challenge(); route(Service-Routes); reply("401", "Unauthorized - Challenging UE"); ELSEIF RES ==XRES then Set -status == "200" Route "OK" to ICSCF ENDIF ENDIF ENDIF In the third phase, the old P-CSCF receives message from UE and compares that if the received request is HANDOVER, then add IpSec SAs to HANDOVER message in TIPSecSAs header.
After ligand activation, AHR undergoes conformational changes that promote its translocation into the nucleus, via [beta] importin, where it is dissociated from the chaperone proteins (Hsp90, XAP2, and p23), and binds to the nuclear translocator AHR (ARNT) [23, 24]; then the formed AHR-ARNT complex (AHRC) binds to xenobiotic responsive elements (XRE) (5'-TNGCGTG-3') located at the enhancer element [25].
Thirteen XRE have been identified in the regulatory region of human CYP1A1 [25].
An expected response XRES = [f.sub.2]k (RAND), the length of XRES is 64bits.
EPS AV consists of [RAND, XRES, a local master key KASME and an AUTN] as shown in fig.1.

The high level of ALDH3 expression involves a strong basal promoter region and a xenobiotic response element (XRE) located within -3.0 kb [191].
