ZigBee tawg, 'Kev Nyab Xeeb Risk' Ntse Teeb Pom Kev Rau Hauv Qhov Kawg'?

[text / Engineering LED Xuchao Peng] 2015 nyuam qhuav tuav hauv Las Vegas \u0026 middot; Black Hat (BlackHat), cov kws tshawb fawb tau tso tawm ib daim ntawv. Daim ntawv tau taw qhia tias qhov tsis txaus ntseeg hauv ZigBee raws tu qauv, LED chaw ntau pob teeb lub hacker tuaj yeem ua mob rau ZigBee network, txhawm rau kom tau txais kev tswj hwm ntawm tag nrho cov khoom siv txuas nrog hauv lub network.Qhov qhov tsis zoo no yog qhov hnyav heev, vim tias kev ruaj ntseg ntawm kev daws yog nyob ntawm nkaus. ntawm tus yuam sij network tsis pub leej twg paub. Thiab, lub teeb chaw ntau pob los ntawm lub teeb ntse ntsuas kub ntsuas nrog rau lub qhov rooj xauv tau sim peb cov yeeb yam, cov neeg muag khoom ntawm cov khoom siv no tsuas yog siv tsawg kawg nkaus ntawm qhov yuav tsum tau muaj rau kev lees paub, tsis muaj lwm txoj hauv kev los txhim kho qib kev ruaj ntseg, yog li muab cov hacker muab kev yooj yim heev. Cov kws tshawb fawb tau ntxiv sau.High fais fab coj dej nyab teeb qhia tias qhov tsis xws luag muaj ntau hom khoom siv, tus neeg nyiag nkas tuaj yeem siv qhov khoob ZigBee raws tu qauv, ntse ntxeem tau koj lub tsev, pub dawb los tswj koj lub network xauv, tswb tshuab, thiab txawm tias muaj peev xwm. hloov koj lub teeb qhov muag teev. Rau ib lub sijhawm nws ua rau muaj kev txhawj xeeb thoob plaws hauv kev lag luam. backpfrontp tam sim no, ZigBee (Zigbee raws tu qauv) raws li IEEE802.15.4 tus qauv, 1000W LED dej nyab lub teeb raws li tus nqi qis, qis zog, luv-ntau wireless network kev sib txuas lus thev naus laus zis, twb tau nthuav dav hauv lub teeb, xws li ntse, smart door locks, motion sensors, kub sensors thiab lwm yam khoom siv sib txuas lus loj, thiab muaj cov tswv cuab siab. Yog li, cov kws tshawb fawb tau hais tias qhov tseeb seb, raws li lub Rooj Sib Tham Black Hat, yuav ua rau muaj kev ruaj ntseg cov khoom lag luam txawj ntse, Engineering LED kuj tau tshawb xyuas nws tus kheej.Qhov kev tshwm sim no peb tau pom tias lub kaus mom dub ntawm General Assembly tau teeb tsa ntawm ZigBee thev naus laus zis tsis zoo. nyob rau hauv raws tu qauv, LED qhov teeb lub rooj plaub tsis muaj cov kev kawm keeb kwm yav dhau thiab lub internal network tso cai yuam sij yog nyuaj rau invasion. Shun Zhou technology khoom thawj coj Jiang Hongfei sawv cev. backpfrontp Raws li Jiang kev taw qhia, Zigbee wireless raws tu qauv yog ib qho kev ruaj ntseg tshaj plaws technology rau ZigBee raws tu qauv, nws tseem tsis tau tshwm sim ua ke lub ntiaj teb no tawg precedent.Engineering LED bay teeb ceeb toom, Zigbee kev ruaj ntseg vim nws systematic tsim, uas siv AES encryption (Advanced Encryption System), nruj 12x lub txhab nyiaj daim npav encryption thev naus laus zis, tab sis, Z-pawg los muab kev txhawb nqa Zigbee, CC2530 kho vajtse txhawb 128bit AES encryption algorithm hauv cov txheej txheem txheej txheem kom tsis txhob cuam tshuam ntawm tib lub cuab yeej, thiab lwm yam khoom siv los tiv thaiv eavesdropping . Kom meej meej hais tias, AES yog ib tug tshiab encryption algorithm yuav siv tau los tiv thaiv hluav taws xob cov ntaub ntawv, uas siv iterative, symmetric tseem ceeb cryptographic pob ntawv, thiab (16 bytes) packets mus encrypt thiab decrypt cov ntaub ntawv 128. Nws siv ib tug voj qauv nyob rau hauv lub voj voog no yog rov xaav. (permutations) thiab hloov (substitutions) cov ntaub ntawv nkag, txhawm rau ua kom muaj kev ruaj ntseg ntawm qhov system. Jiang Hongfei sawv cev. backpfrontp hauv qab Engineering LED arena teeb kuj summed Zigbee peb txoj kev ruaj ntseg mechanisms, thiaj li yuav txhim kho cov ntaub ntawv kev ruaj ntseg: backpfrontp 1), cov qauv sab hauv ntawm kev ruaj ntseg; backpfrontp ZigBee raws tu qauv kom muaj kev ruaj ntseg network, tag nrho cov khoom siv yuav tsum tau tsim tsom iav Cov chij ua ntej kev ruaj ntseg tau qhib, teeb tsa tus password qub, tus password qub tuaj yeem raug teeb tsa ua ntej rau txhua lub cuab yeej hauv lub network lossis teeb tsa tsuas yog rau tus tswj hwm, thiab ces faib rau tag nrho cov khoom siv yog tias lub network. Nco ntsoov tias, nyob rau yav tom ntej, tus password yuav raug faib rau lawv txhua tus los koom nrog cov khoom siv network. Yog li, koom nrog lub network thaum lub sijhawm tsis muaj zog dhau los, tab sis nws zoo li ua kom tiav hauv kaum milliseconds. backpfrontp 2), nruj tswj kev nkag mus rau hauv network; Hauv kev ruaj ntseg network, thaum lub cuab yeej koom nrog lub network yuav raug qhia tias lub chaw ntseeg siab. Credit Center tau tso cai kom nyob twj ywm hauv lub network ntaus ntawv lossis kev nkag mus rau hauv lub network yog tsis pom zoo rau txoj cai xaiv lub cuab yeej, coj lub chaw ntau pob dej nyab lub chaw tso siab tuaj yeem txiav txim siab seb puas yuav tso cai rau lub cuab yeej rau hauv lub network ntawm txhua txoj hauv kev, ib qho ntawm Trust Center tsuas yog ib tug ntaus ntawv nyob rau hauv ib tug luv luv lub sij hawm lub qhov rais mus koom lub network, uas tus neeg siv tsis tuaj yeem hla txoj kev tso cai; backpfrontp 3), daim ntawv thov cov ntaub ntawv kev ruaj ntseg; kev ntseeg siab tuaj yeem hloov kho lub network password raws li lawv tus kheej txiav txim siab. Cov neeg tsim khoom siv los hloov kho txoj cai hloov tshiab network password, qhov chaw Trust Center tuaj yeem siv los qhia txog txoj cai raws li kev siv ntawm cov neeg ua haujlwm txhim kho, lub tswv yim yuav raug hloov kho nyob rau ib ntus raws li koj lub network password cycles. backpbackpfrontp Tsis tas li ntawd, feem ntau ntawm cov tuam txhab tsim hluav taws xob hauv tsev ntawm Zigbee thev naus laus zis daim ntawv cog lus, xws li millet, gym teeb Lenovo, OU thiab lwm yam, uas yog ua raws li kev hloov kho kev pom zoo raws li kev cog lus ntawm kev sib koom ua ke, los ua lawv tus kheej txoj cai, yog li nrog Lwm lub tshuab Zigbee tsis cuam tshuam nrog. Jiang Hongfei tau hais, raws li qhov kev txiav txim siab saum toj no, nws ntseeg hais tias cov hackers xav kom nkag mus rau hauv cov txheej txheem nyuaj yog qhov loj heev. backpfrontp qhov tseeb, rau cov kws tshaj lij kev tshaj lij hackers, thiab tej zaum kuj muaj kev cuam tshuam ntawm cov cuab yeej ntse hauv tsev yuav ua tau, tab sis rau cov neeg siv nruab nrab, qhov no tsis tuaj yeem paub. Ntxiv mus, siv zog ntau heev, txhais tau tias dag? Yog li rau Black Hat tawg Zigbee kev nyab xeeb txaus ntshai, peb so me ntsis, ua kom zoo dua cov khoom siv teeb pom kev zoo mus! Rov qab
