Nubundi buryo bwitumanaho mugihe cyibiza,LTE imiyoboro yihariyefata politiki zitandukanye z'umutekano mu nzego nyinshi kugirango wirinde abakoresha batemewe kubona cyangwa kwiba amakuru, no kurinda umutekano wibimenyetso byabakoresha namakuru yubucuruzi.
Umubiri
●Emera imirongo yihariye yabugenewe kugirango itandukane muburyo bwo kubona ibikoresho hamwe na bande idafite uruhushya.
●Abakoresha bakoreshaIWAVE tactique lte igisubizoterefone zigendanwa n'amakarita ya UIM kugirango wirinde kwinjira mu bikoresho bitemewe.
Umuyoboro
●Milenage algorithm na bitanu-tuple yo kwemeza ibipimo bikoreshwa kugirango tugere ku buryo bubiri bwo kwemeza hagati ya UE numuyoboro.
Iyo itumanaho ryinjiye murusobe, umuyoboro uzemeza itumanaho kugirango wirinde abakoresha batemewe kwinjira.Mugihe kimwe, terminal nayo izemeza umuyoboro kugirango wirinde kugera kumurongo wa fishing.
Igishushanyo 1: Urufunguzo rwibanze Algorithm
Igishushanyo 2: Biterwa nibipimo byo kwemeza
●Ikirere cyerekana ibimenyetso byerekana ubutumwa bushyigikira kurinda no kugenzura, kandi amakuru yumukoresha nayo ashyigikira ibanga.Ubunyangamugayo no gushishoza kurinda algorithm ikoresha urufunguzo rwa 128-bit kandi ifite imbaraga z'umutekano mwinshi.Igishushanyo gikurikira 3 cyerekana ibisekuruza byokwemeza ibipimo bifitanye isano, aho HSS na MME byombi ari module yimbere yimbere ya tactique ya lte.
Igishushanyo 3: Igisekuru cyibikorwa byurwego rwigenga rwemeza ibipimo
Igishushanyo 4: Igisekuru cyibikorwa byo kwemeza terminal
●Iyo4g lte itumanaho ryamakurukuzerera, guhinduranya cyangwa kongera kwinjira hagati ya eNodeBs, irashobora gukoresha uburyo bwo kongera kwemeza kugirango yongere yemeze kandi ivugurure urufunguzo kugirango umutekano ube mugihe cyo kugendanwa.
Igishushanyo 5: Gukoresha urufunguzo mugihe uhindura
Igishushanyo 6: Kwemeza ibihe byigihe na eNB
●Kwemeza ibimenyetso byerekana inzira
Kwemeza birakenewe mugihe UE itangiye guhamagarwa, yitwa, kandi ikiyandikisha.Encryption / ubunyangamugayo burashobora kandi gukorwa nyuma yo kwemeza birangiye.UE ibara RES (ibipimo byo gusubiza ibyemezo muri SIM karita), CK (urufunguzo rwibanga) na IK (urufunguzo rwo kurinda ubunyangamugayo) bishingiye kuri RAND yoherejwe numuyoboro wigenga wa LTE, ikandika CK na IK nshya muri karita ya SIM.hanyuma wohereze RES gusubira kumurongo wigenga wa LTE.Niba umuyoboro wigenga wa LTE ubona ko RES ari yo, inzira yo kwemeza irangira.Nyuma yo kwemeza neza, umuyoboro wigenga wa LTE uhitamo niba ugomba gukora inzira yo kugenzura umutekano.Niba ari yego, iterwa numuyoboro wigenga wa LTE, kandi kurinda encryption / ubunyangamugayo bishyirwa mubikorwa na eNodeB.
Igishushanyo 7: Uburyo bwo kwemeza ibimenyetso
Igishushanyo 8: Uburyo bwizewe bwerekana ibimenyetso
Porogaramu
●Iyo abakoresha babonye, kwemeza umutekano bishyirwa mubikorwa murwego rwo gukumira abakoresha bitemewe.
●Abakoresha amakuru arashobora gukoresha uburyo bwa IPSEC kugirango umutekano wamakuru ukoreshwe.
●Iyo ikibazo kibonetse mugihe cyo gusaba, umukoresha ufite ikibazo arashobora guhatirwa kujya kumurongo muguteganya ibikorwa nko guhagarika ku gahato no kwica kure.
Umutekano w'urusobe
●Sisitemu yubucuruzi yihariye irashobora guhuza umuyoboro wo hanze ukoresheje ibikoresho bya firewall kugirango umenye neza ko umuyoboro wigenga urinzwe ibitero byo hanze.Muri icyo gihe, topologiya y'imbere y'urusobe irakingiwe kandi ihishwa kugirango ikumire imiyoboro kandi ikomeze umutekano wurusobe.
