●Milenage algorithm ndi magawo asanu otsimikizika amatuples amagwiritsidwa ntchito kukwaniritsa njira ziwiri zotsimikizika pakati pa UE ndi netiweki.
Pamene terminal ifika pa netiweki, netiweki imatsimikizira terminal kuti aletse ogwiritsa ntchito osaloledwa kulowa.Nthawi yomweyo, terminal idzatsimikiziranso netiweki kuti ipewe mwayi wopezeka pa intaneti ya phishing.

Kutsimikizika kumafunika pamene UE iyambitsa kuyimba, kuyitana, ndikulembetsa.Chitetezo cha encryption/umphumphu chingathenso kuchitidwa pambuyo poti kutsimikizika kumalizidwe.UE imawerengera RES (zigawo zoyankhira zotsimikizira mu SIM khadi), CK (kiyi yobisa) ndi IK (kiyi yoteteza kukhulupirika) kutengera RAND yotumizidwa ndi netiweki yachinsinsi ya LTE, ndikulemba CK ndi IK yatsopano mu SIM khadi.ndikutumizanso RES ku netiweki yachinsinsi ya LTE.Ngati intaneti yachinsinsi ya LTE ikuwona kuti RES ndi yolondola, ndondomeko yotsimikizika imatha.Pambuyo potsimikizira bwino, makina achinsinsi a LTE amasankha ngati angagwire ntchito yoyang'anira chitetezo.Ngati inde, imayambitsidwa ndi netiweki yachinsinsi ya LTE, ndipo chitetezo cha encryption/integrity chimakhazikitsidwa ndi eNodeB.

●Ogwiritsa akalowa, kutsimikizika kwachitetezo kumakhazikitsidwa pagawo la pulogalamu kuti aletse ogwiritsa ntchito osaloledwa.
●Zambiri za ogwiritsa ntchito zitha kugwiritsa ntchito njira ya IPSEC kutsimikizira chitetezo cha ogwiritsa ntchito.
●Vuto likapezeka panthawi yogwiritsira ntchito, wogwiritsa ntchitoyo ali ndi vuto amatha kukakamizidwa kuti asagwiritse ntchito intaneti pokonza zochitika monga kuchotsedwa mokakamizidwa ndi kupha anthu akutali.
