Kuphulika kwa ZigBee, 'Chiwopsezo Chachitetezo' Kuwunikira Mwanzeru Mu 'Mapeto Akufa'?

[zolemba / Engineering LED Xuchao Peng] 2015 posachedwapa ku Las Vegas \u0026 middot; Black Hat (BlackHat), ofufuzawo adatulutsa pepala. Pepalalo linanena kuti cholakwika mu protocol ya ZigBee, kuwala kwa bwalo la LED ndi wowononga akhoza kuvulaza maukonde a ZigBee, kuti athe kuwongolera zida zonse zolumikizidwa pa netiweki. pa makiyi a netiweki chinsinsi. Ndipo, nyali zapabwalo lochokera ku sensor yotentha ya babu lanzeru komanso loko yotsekera zitseko zidayesa chiwonetsero chathu, ogulitsa zida izi kuti atumize zocheperako zofunikira kuti zitsimikizidwe, palibe njira zina zosinthira chitetezo, motero hacker imapereka mwayi waukulu kwambiri. Ofufuzawo anawonjezera analemba.Mkulu mphamvu anatsogolera chigumula kuwala inanena kuti chilema kumaphatikizapo mitundu yosiyanasiyana ya zida, ndi owononga angagwiritse ntchito mipata ZigBee protocol zipangizo, wanzeru kuukira nyumba yanu, ufulu kulamulira maloko maukonde anu, machitidwe Alamu, ndipo ngakhale athe kusintha mababu anu. Kwa nthawi yayitali zidayambitsa nkhawa zambiri m'makampani. backpfrontp present, ZigBee (Zigbee protocol) yochokera pa IEEE802.15.4 standard, 1000W LED kusefukira kwa kuwala ngati njira yotsika mtengo, yotsika mphamvu, yaufupi yolumikizira mawayilesi opanda zingwe, yomwe ilipo kale mu nyali, monga anzeru, zokhoma zitseko zanzeru, masensa oyenda, masensa kutentha ndi zida zina zazikulu zikutuluka maukonde, ndipo ali umwini mkulu. Kotero, ofufuzawo adanena kuti ngati, monga msonkhano wa Black Hat, udzatsogolera kuzinthu zanzeru zachitetezo, Engineering LED inachitanso kafukufuku wake.Chochitika ichi tawona kuti chipewa chakuda pa General Assembly chinakhazikitsidwa pa zovuta zamakono za ZigBee. mu mulingo wa protocol, kuwala kwa tunnel ya LED mlanduwo ulibe luso lakumbuyo ndipo makiyi ovomerezeka amkati ndi ovuta kuwukira. Woyimira zaukadaulo wa Shun Zhou Jiang Hongfei woyimira. backpfrontp Malingana ndi chiyambi cha Jiang, Zigbee wireless protocol ndi imodzi mwa teknoloji yotetezeka kwambiri ya ZigBee protocol, sinawonekere palimodzi padziko lonse lapansi. Encryption System), rigor 12x banki khadi kubisa luso, koma, Z-stack kupereka mabuku thandizo Zigbee, CC2530 hardware thandizo 128bit AES kabisidwe aligorivimu mu protocol stack pofuna kupewa kusokonezedwa ndi zida zomwezo, ndi zipangizo zina kupewa kumvetsera. . Mwachionekere, AES ndi aligorivimu watsopano kubisa angagwiritsidwe ntchito kuteteza deta pakompyuta, amene amagwiritsa iterative, symmetric kiyi cryptographic paketi, ndi (16 bytes) mapaketi encrypt ndi decrypt deta 128. Iwo amagwiritsa ntchito kuzungulira dongosolo mkombero ndi kusamutsidwa mobwerezabwereza. (zololeza) ndi zolowetsa (zosintha) zolowetsa, kuti zitsimikizire chitetezo cha dongosolo. Kuyimira kwa Jiang Hongfei. backpfrontp pansipa Engineering LED bwalo kuwala anafotokozeranso mwachidule Zigbee njira zitatu zotetezera, pofuna kupititsa patsogolo chitetezo cha deta: backpfrontp 1), mkati mwa chitetezo; Backpfrontp ZigBee protocol kuti mukhale ndi netiweki yotetezeka, zida zonse ziyenera kupangidwa magalasi Mbendera yachitetezo isanachitike imayatsidwa, khazikitsani mawu achinsinsi, mawu achinsinsi okhazikika amatha kukonzedweratu ku chipangizo chilichonse pa netiweki kapena kukonzedwa kokha kwa wogwirizanitsa, ndi kenako anagawira zipangizo zonse ngati maukonde. Dziwani kuti, m'tsogolomu, mawu achinsinsi adzagawidwa kwa aliyense wa iwo kuti agwirizane ndi zida zapaintaneti. Chifukwa chake, lowani netiweki panthawi yakufooka kumakhala, koma kumakhala kumalizidwa mkati mwa ma milliseconds khumi. backpfrontp 2), okhwima maukonde kulamulira; Mu maukonde otetezeka, pamene chipangizo alowa maukonde adzauzidwa kuti malo trust. Ngongole Center walola kukhalabe mu chipangizo maukonde kapena mwayi maukonde amakanidwa ufulu umenewu kusankha chipangizo, anatsogolera bwalo floodlights malo kukhulupirira akhoza kusankha ngati kulola chipangizo mu maukonde kudzera njira iliyonse zomveka, mmodzi wa Trust Center ndi yekha. chipangizo chimodzi mu nthawi yochepa zenera nthawi kujowina maukonde, amene wosuta sangathe kulambalala ndondomeko chilolezo; backpfrontp 3), chitetezo deta ntchito; trust center imatha kusintha mawu achinsinsi pa intaneti malinga ndi malingaliro awo. Madivelopa ntchito kusintha update ndondomeko maukonde achinsinsi, kusakhulupirika Trust Center angagwiritsidwe ntchito kufotokoza mfundo mogwirizana ndi kukhazikitsidwa kwa ogwira ntchito chitukuko, njira adzakhala kusinthidwa nthawi zonse malinga ndi maukonde anu achinsinsi mkombero. backpbackpfrontp Komanso, ambiri opanga zoweta za Zigbee teknoloji mgwirizano, monga mapira, magetsi magetsi Lenovo, OU etc., amene zachokera pangano kusinthidwa pamaziko a mgwirizano mgwirizano, kukhala protocol awo eni, kotero ndi machitidwe ena a Zigbee sangagwirizane. Jiang Hongfei wotchulidwa, kutengera zomwe tafotokozazi, akukhulupirira kuti hackers akufuna kulowa muzovuta dongosolo ndi lalikulu kwambiri. chowonadi cha backpfrontp, kwa ozembera akatswiri otsogola, komanso mwinanso kuwukira kwa zida zanzeru zakunyumba zomwe zingatheke, koma kwa ogwiritsa ntchito wamba, izi sizingachitike. Komanso, kugwiritsa ntchito khama kwambiri, kutanthauza bodza? Chifukwa chake ku Black Hat kuphulika kwachitetezo cha Zigbee, timapumula pang'ono, timachita bwino zowunikira zanzeru zipite! Zotsalira
