Ngalo lonke ixesha utshintsho oluya kumgangatho omtsha wonxibelelwano lweselula aluthethi nje ukwanda kwesantya sokutshintshiselana kwedatha, kodwa kwakhona kwenza uxhulumaniso luthembeke ngakumbi kwaye lukhuselwe ekufikeleleni okungagunyaziswanga. Ukwenza oku, bathatha ubuthathaka obufunyenwe kwiiprothokholi zangaphambili kwaye basebenzise iindlela ezintsha zokuqinisekisa ukhuseleko. Kule nkalo, unxibelelwano usebenzisa i-5G protocol ithembisa ukuba inokwethenjelwa ngakumbi kunonxibelelwano usebenzisa iprotocol ye-4G (LTE), nangona kunjalo, ayibandakanyi ithuba lokufumana ubuthathaka "5G" kwixesha elizayo. Ngokukwanjalo, iminyaka yokusebenza kwe-4G ayizange ikhulule le protocol ekuvezeni ubuthathaka obuninzi obutsha. Umzekelo wamva nje wokuqinisekisa le thesis luphononongo olwenziwa ziingcali zokhuseleko zaseMzantsi Korea, ezifumene i-4 entsha yobuthathaka obunobungozi kwiprotocol ye-36G.
Abaphandi kwiKorea Advanced Institute of Science and Technology (KAIST) basebenzise indlela efanayo yokufumana ubuthathaka kwiprotocol ye-LTE (inethiwekhi) esetyenziselwa ukufumana izisombululo ezinengxaki kwisoftware yePC kunye abancedisiLe ndlela ebizwa ngokuba yi-fuzzing ibandakanya ukuhlasela (ukulayisha) inkqubo enolandelelwano lwedatha engalunganga, engalindelekanga, okanye engacwangciswanga. Emva komthwalo, impendulo yenkqubo iyafundwa, kwaye iimeko zokuzikhusela okanye ukunyuka kohlaselo kuyaphuhliswa. Lo msebenzi ungenziwa ngokuzenzekelayo, unika inkqubo yokusasazwa inkqubo yokudlulisa nokufumana idatha, ngelixa iimeko zohlaselo kunye nohlalutyo lwedatha efunyenweyo ziphuhliswa ngesandla. Umzekelo, iingcali ze-KAIST ziphuhlise usetyenziso lwe-LTEFuzz lokuvavanya ukhuseleko lweprotocol ye-LTE kunye nokufumana ubuthathaka, kodwa zithembisa ukuba aziyi kuyikhupha esidlangalaleni, kuphela kubavelisi bezixhobo kunye nabaqhubi beenkonzo zonxibelelwano.
Ukusebenzisa i-LTEFuzz, ngaphezulu kwe-50 yobuthathaka yafunyanwa, i-36 kubo yayintsha ngokupheleleyo. Indlela yasivumela ukuba sifumane i-15 esele ikwazi ubuthathaka, eyaqinisekisa ukuchaneka kweteknoloji ekhethiweyo (ukuba iyaziwa, kutheni ivaliwe?). Uvavanyo lwenziwa kuthungelwano lwabaqhubi ababini abangachazwanga ngamagama kunye nentsebenziswano nabo, ngoko ke abasebenzisi abaqhelekileyo abazange bachaphazeleke. Kwaye kwatyhilwa izinto ezininzi ezinomdla. Kwakunokwenzeka ukumamela ababhalisile, ukufunda idatha xa utshintshisa izikhululo ezisisiseko kunye nezixhobo, ukuthumela i-SMS yobuxoki, ukuvala iifowuni ezingenayo, ukukhupha ababhalisile kwinethiwekhi, ukulawula i-traffic kunye nokwenza okungakumbi. Iingcali ze-KAIST zazisa abathengisi kunye ne-3GPP kunye nemibutho ye-GSMA malunga nabo bonke ubuthathaka obufunyenweyo, kubandakanywa "imingxuma" kwizixhobo zezikhululo zesiseko seselula.
