I-TD-LTE Network Security Strategy yangasese

20 ukubukwa

Njengenye indlela yokuxhumana ngesikhathi senhlekelele,Amanethiwekhi ayimfihlo e-LTEzamukele izinqubomgomo zokuphepha ezihlukene emazingeni amaningi ukuze kuvinjelwe abasebenzisi abangekho emthethweni ekufinyeleleni noma bentshontshe idatha, nokuvikela ukuvikeleka kokusayina komsebenzisi nedatha yebhizinisi.

Ungqimba Lomzimba

Sebenzisa amabhendi efrikhwensi azinikele ukuze uhlukanise ngokoqobo ukufinyelela kwezinto zokusebenza ngebhendi yefrikhwensi engagunyaziwe.
Abasebenzisi basebenzisaIWAVE isixazululo se-tactical lteomakhalekhukhwini namakhadi e-UIM ukuvimbela ukufinyelela kwedivayisi okungekho emthethweni.

 

Isendlalelo Senethiwekhi

I-algorithm ye-Milenage kanye namapharamitha wokuqinisekisa ama-athomu amahlanu asetshenziselwa ukuzuza ukuqinisekiswa kwezindlela ezimbili phakathi kwe-UE nenethiwekhi.
Uma itheminali ifinyelela kunethiwekhi, inethiwekhi izoqinisekisa itheminali ukuvimbela abasebenzisi abangekho emthethweni ukuthi bafinyelele.Ngesikhathi esifanayo, itheminali izophinde iqinisekise inethiwekhi ukuze ivimbele ukufinyelela kunethiwekhi yobugebengu bokweba imininingwane ebucayi.

Imilayezo yesignali yokusebenzelana komoya isekela ukuvikelwa kobuqotho nokubethela, futhi idatha yomsebenzisi iphinde isekele ukubethela.I-algorithm yokuvikela ubuqotho nokubethela isebenzisa ukhiye wobude obungu-128-bit futhi inamandla okuphepha aphezulu.Umfanekiso ongezansi wesi-3 ubonisa inqubo yokukhiqiza amapharamitha ahlobene nokuqinisekisa, lapho i-HSS ne-MME zombili zingamamojula angaphakathi asebenzayo enethiwekhi ye-tactical lte.

Lapho i-Itheminali yedatha engenantambo engu-4g lteizulazula, ishintshe noma iphinde ifinyelele phakathi kwama-eNodeB, ingasebenzisa indlela yokuqinisekisa kabusha ukuze iphinde iqinisekise futhi ibuyekeze okhiye ukuze kuqinisekiswe ukuphepha phakathi nokufinyelela kweselula.

Ukuphatha ukhiye lapho ushintsha

Inqubo yokusayina yokuqinisekisa
Ukuqinisekisa kuyadingeka lapho i-UE iqala ucingo, ibizwa, futhi ibhalisa.Ukuvikela ukubethela/ubuqotho nakho kungenziwa ngemva kokuqedwa kokuqinisekisa.I-UE ibala i-RES (amapharamitha empendulo yokuqinisekisa ku-SIM khadi), i-CK (ukhiye wokubethela) kanye ne-IK (ukhiye wokuvikela ubuqotho) ngokusekelwe ku-RAND ethunyelwe inethiwekhi yangasese ye-LTE, bese ibhala i-CK ne-IK entsha ku-SIM khadi.bese uthumela i-RES emuva kunethiwekhi yangasese ye-LTE.Uma inethiwekhi yangasese ye-LTE ibheka ukuthi i-RES ilungile, inqubo yokuqinisekisa iyaphela.Ngemuva kokuqinisekisa ngempumelelo, inethiwekhi eyimfihlo ye-LTE inquma ukuthi isebenzise inqubo yokulawula ukuvikeleka.Uma uthi yebo, iqaliswa inethiwekhi eyimfihlo ye-LTE, futhi ukubethela/ubuqotho ukuvikelwa kusetshenziswa i-eNodeB.

Uhlelo Lokusebenza
Lapho abasebenzisi befinyelela, ukuqinisekiswa kokuvikeleka kusetshenziswa kusendlalelo sohlelo lokusebenza ukuvimbela ukufinyelela komsebenzisi okungekho emthethweni.
Idatha yomsebenzisi ingasebenzisa indlela ye-IPSEC ukuze kuqinisekiswe ukuphepha kwedatha yomsebenzisi.
Uma inkinga itholwa ngesikhathi sohlelo lokusebenza, umsebenzisi onenkinga angaphoqeleka ukuthi ahambe ngokungaxhunyiwe ku-inthanethi ngokuhlela imisebenzi efana nokunqanyulwa okuphoqelekile kanye nokubulawa kude.

Ukuphepha Kwenethiwekhi
Isistimu yebhizinisi yenethiwekhi yangasese ingaxhuma kunethiwekhi yangaphandle ngokusebenzisa imishini yokuvikela umlilo ukuze kuqinisekiswe ukuthi inethiwekhi yangasese ivikelekile ekuhlaselweni kwangaphandle.Ngesikhathi esifanayo, i-topology yangaphakathi yenethiwekhi ivikelekile futhi ifihliwe ukuvimbela ukuchayeka kwenethiwekhi nokugcina ukuphepha kwenethiwekhi.
