Raws li lwm txoj kev sib txuas lus thaum muaj kev puas tsuaj,LTE private networkstxais yuav cov cai tswj kev ruaj ntseg sib txawv ntawm ntau qib los tiv thaiv cov neeg siv tsis raug cai los ntawm kev nkag los yog nyiag cov ntaub ntawv, thiab tiv thaiv kev ruaj ntseg ntawm cov neeg siv cov teeb liab thiab cov ntaub ntawv lag luam.
Lub cev txheej
●Txais siv cov kab hluav taws xob tshwj xeeb rau lub cev kom cais tawm cov khoom siv nrog cov tsis muaj ntawv tso cai ntau zaus.
●Cov neeg siv khoom sivIWAVE tactical lte dawscov xov tooj ntawm tes thiab UIM daim npav los tiv thaiv kev nkag mus rau cov cuab yeej tsis raug cai.
Network Txheej
●Lub Milenage algorithm thiab tsib-tuple authentication tsis yog siv los ua kom tiav ob txoj kev authentication ntawm UE thiab lub network.
Thaum lub davhlau ya nyob twg nkag mus rau lub network, lub network yuav txheeb xyuas lub davhlau ya nyob twg los tiv thaiv cov neeg siv tsis raug cai los ntawm kev nkag mus.Nyob rau tib lub sijhawm, lub davhlau ya nyob twg tseem yuav txheeb xyuas lub network kom tsis txhob nkag mus rau phishing network.

Daim duab 2: Dependencies ntawm authentication parameters
●Cua interface signaling messages txhawb kev ruaj ntseg tiv thaiv thiab encryption, thiab cov ntaub ntawv ntawm cov neeg siv kuj txhawb encryption.Kev ncaj ncees thiab kev tiv thaiv encryption algorithm siv 128-ntsis ntev tus yuam sij thiab muaj kev ruaj ntseg siab.Daim duab 3 hauv qab no qhia txog kev tsim cov txheej txheem ntawm kev lees paub txog qhov tsis muaj tseeb, nyob rau hauv uas HSS thiab MME yog ob qho tib si hauv kev ua haujlwm modules ntawm tactical lte network.

Daim duab 4: Tsim cov txheej txheem ntawm lub davhlau ya nyob twg authentication tsis
●Thaum lub4g lte wireless cov ntaub ntawv davhlau ya nyob twgroams, keyboards lossis rov nkag ntawm eNodeBs, nws tuaj yeem siv cov txheej txheem rov ua pov thawj kom rov txheeb xyuas dua thiab hloov cov yuam sij kom muaj kev nyab xeeb thaum nkag mus rau hauv xov tooj.

Daim duab 6: Periodic authentication ntawm terminals los ntawm eNB
●Authentication signaling txheej txheem
Kev lees paub yog xav tau thaum UE pib hu, hu, thiab sau npe.Kev tiv thaiv encryption / kev ncaj ncees kuj tseem tuaj yeem ua tau tom qab kev lees paub tiav.UE suav RES (kev lees paub cov lus teb tsis zoo hauv SIM daim npav), CK (tus yuam sij encryption) thiab IK (tus yuam sij tiv thaiv kev ncaj ncees) raws li RAND xa los ntawm LTE ntiag tug network, thiab sau tus tshiab CK thiab IK rau hauv SIM daim npav.thiab xa RES rov qab mus rau LTE ntiag tug network.Yog tias LTE ntiag tug network txiav txim siab tias RES yog lawm, cov txheej txheem authentication xaus.Tom qab ua tiav kev lees paub, LTE ntiag tug network txiav txim siab seb puas yuav ua tiav cov txheej txheem tswj kev nyab xeeb.Yog tias yog, nws tau tshwm sim los ntawm LTE ntiag tug network, thiab kev tiv thaiv encryption / kev ncaj ncees yog siv los ntawm eNodeB.

Daim Ntawv Thov Txheej
●Thaum cov neeg siv nkag mus, kev lees paub kev ruaj ntseg yog siv rau ntawm daim ntawv thov txheej los tiv thaiv cov neeg siv tsis raug cai.
●Cov neeg siv cov ntaub ntawv tuaj yeem siv IPSEC mechanism los xyuas kom cov neeg siv cov ntaub ntawv ruaj ntseg.
●Thaum muaj teeb meem tshwm sim thaum lub sijhawm thov, tus neeg siv nrog qhov teeb meem tuaj yeem raug yuam kom mus offline los ntawm kev teem sijhawm ua haujlwm xws li yuam kev txiav tawm thiab tua tej thaj chaw deb.
Network Security
●Cov kev lag luam ntiag tug network tuaj yeem txuas mus rau sab nraud network los ntawm cov khoom siv hluav taws xob kom ntseeg tau tias lub network ntiag tug tiv thaiv los ntawm kev tawm tsam sab nraud.Nyob rau tib lub sijhawm, sab hauv topology ntawm lub network yog thaiv thiab zais kom tsis txhob cuam tshuam lub network thiab tswj kev ruaj ntseg network.
