Kwadalwa ngo 2025.11.28
Isingeniso: Inkinga Yokuphepha Eyimfihlo Emakhamereni Axhunyiwe
Njengoba izimoto ezizimele, amadolobha akhanyayo, kanye nezinsiza ze-IoT ziba yizinto ezivamile, amamojula wekhamera athuthuke abe amathuluzi okuthola izithombe ayisidingo esibalulekile sedatha. Nokho, le shintsho iveze iqiniso elikhathazayo: u-78% wezokuphepha kwekhamera yezimboni ngo-2024 uvela ekudlulisweni kwedatha okungavikelekile noma ezakhiwo eziphambene, ngokusho kwe-IoT Security Foundation. Amamojula wekhamera ajwayelekile athembele ezinyathelweni zokuphepha eziphukile ezingakwazi ukubhekana nezingozi zokuphela kokuphela, kushiya idatha ebonakalayo ebucayi ivulnerable ekuthintweni, ekutholeni, nasekwephulweni kwemfihlo.
Ngena kwi-MIPI (Mobile Industry Processor Interface) ama-module wekhamera – hhayi nje kuphela isikh standards sokuxhumana, kodwa futhi i-ecosystem yokuphepha ephelele. Ngokwehlukile nezixazululo ezijwayelekile ezihlanganisa ukuphepha njengokucabanga kokugcina, i-architecture ye-MIPI ifaka ukuvikelwa kuzo zonke izingxenye: kusukela kumahardware wesensori kuya kumaphrothokholi wokudluliswa kwedatha. Kulesi sihloko, sizokhuluma ngezinsiza ezihlukile zokuphepha ze-MIPI amakhamera amamojulaokubuyisela emuva ukuphepha ezinhlelweni zokubona ezixhunyiwe.
1. Ukuvikelwa Kwedatha Okuqondile: Ukuvala Isikhala Ezinhlelweni Zendabuko
Amamojula ekhanda endabuko avamise ukufaka idatha kuphela ngesikhathi esithile sokudluliswa, okwakha "izikhala zokuphepha" phakathi kwezinsiza zokuhlola nezinsiza zokucubungula. I-MIPI’s Camera Security Framework ikhipha le mphumela ngeqiniso lokuvikela kusuka ekuqaleni kuya ekugcineni kumafayela edatha e-MIPI CSI-2® – i-interface yeqiniso yezithombe zezimoto nezokuxhumana kwe-IoT.
Indlela Esisebenza Ngayo:
• Ukuqinisekisa Okufakiwe Kwe-Hardware: I-MIPI CSE™ (Izandiso Zesevisi Zekhamera) v2.0 ihlanganisa ukuvikelwa kwe-AES-256 ngqo kwi-physical layer yesensori, iqinisekisa ukuthi idatha ye-pixel ivikelwe emthonjeni ngaphambi kokudluliswa. Lokhu kuvimba ukuhlaselwa komuntu ophakathi okusebenzisa idatha engavikelwanga ngesikhathi sokudluliswa.
• Ukuqinisekiswa Kwezehlakalo: Ngokuqhuba ama-Message Authentication Codes (MAC), le framework iqinisekisa ubuqiniso bedatha kuzo zonke izinyathelo. Ngokwehlukile kumaphuzu e-CRC ayisisekelo athola kuphela amaphutha okungafanele, ama-MAC avimbela ukuhlinzwa okubi – kubalulekile ezinhlelweni ezibalulekile zokuphepha ezifana ne-ADAS (Izinhlelo Zokwesekwa Kokuqhuba Okuthuthukisiwe).
• Ukuvikeleka KweMiyalo: MIPI CCISE™ (Izandiso Zesevisi Yokulawula Nokulawula) ivikela izimpawu zokulawula ezisekelwe ku-I2C, ivimbela abahlaseli ekuphenduleni izinzwa ukuze zikhishwe idatha eyinqaba (isb., ukuguqula ukufundwa kokukude ezimotweni ezizimele).
Umthelela Wangempela: Umkhiqizi ophambili wezimoto wehlise izigameko zokuphepha ezihlobene ne-ADAS ngama-92% ngemuva kokwamukela uhlaka lwe-MIPI, njengoba kubikwe kwiMiphumela yeMpi ye-MIPI ye-2024. Ngokufaka ukufihla kokubili idatha yezithombe nemiyalo yokulawula, uhlelo lwaluvimba imizamo yokuphazamisa ama-algorithms wokuthola imigqa.
2. Ukuqinisekiswa Kwezithako: Ukuqinisa Uhlelo Lokuhlinzeka
Amamojula ekhamera angama- counterfeit abeka ingozi ephindwe kabili: ahluleka ukusebenza futhi adala izindlela ezisemva zokuhlaselwa kwe-cyber. Uhlelo lokuqinisekisa lwe-MIPI olwakhiwe ngamasu luphendula lokhu ngokuhlola ubuqiniso bezingxenye kuwo wonke amazinga wesikhwama sokuhlinzeka.
Inqubo Yokuhlola Eyizigaba Ezintathu:
Izinga Lokuphepha | Umsebenzi | Ukusetshenziswa |
Izinga C (Ukuhlinzekwa Okuphephile) | Faka iziqu ezihlukile (izitifiketi/PSK) kumasensori ngesikhathi sokukhiqiza | Qinisekisa ukuthi kuphela izingxenye ezivunyelwe zingena emgqeni wokuhlinzeka |
Izinga B (Ukusungulwa KweSeshini Evikelekile) | Isebenzisa i-DMTF SPDM protocol yokuxhumana okuvikelekile phakathi kwezinsiza nezinsiza ze-ECU. | Ivimbela amadivayisi angagunyaziwe ukuthi axhume kuhlelo. |
Izinga A (Ukuqinisekiswa Kwe-Runtime) | Ukuqhubeka kuqinisekisa ubunikazi bezingxenye ngesikhathi sokusebenza | Ithola ama-modules aguquliwe noma ashintshiwe ngesikhathi sangempela |
Le ndlela ibalulekile ikakhulukazi emikhakheni efana nezimoto nezempilo, lapho ama-sensor ama-fake angaholela eziphethweni ezibulalayo. Isibonelo, ukuqinisekiswa kwe-MIPI kuvinjezele isenzakalo sika-2023 lapho ama-cameras e-ADAS ama-fake ayefakwa ezimotweni zokuhweba - isakhiwo sathola iziqu ezingahambelani ngaphambi kokuthi izimoto ziqale ukusebenza.
3. Ukulawula Ukuvikeleka Okunembile: Ukulinganisa Ukuvikelwa Nokusebenza
Enye yezinselelo ezinkulu ekuphepheni kwemakhamera ukuhlela ukuvikelwa okuqinile nokusebenza kwesikhathi sangempela. I-MIPI ixazulula lokhu ngezilungiselelo zokuphepha eziguquguqukayo, ezithile zokusebenza ezigwema "ukuhlinzeka okukodwa okuhambelana nazo zonke" okukhathazayo kwezixazululo zendabuko.
Izici Eziyinhloko Zokuguquguquka:
• Izinguquko Zokuphepha (SV-1 kuya ku-SV-5): Ivumela abaklami bezinhlelo ukukhetha ukuhlanganiswa kokufihla nokuvikeleka kokwethembeka ngokususelwa ekutheni idatha ibucayi kangakanani. Isibonelo:
◦ SV-1 (Ukuqina Kuphela): Ikhono elihle lokubuka izithombe zokuhlola ezingabalulekile ukuze kugcinwe ibhendi.
◦ SV-5 (Ukufihla Okugcwele + Ukuqina): Kubalulekile kwedatha ethinta ubumfihlo efana nokuhlonza ubuso
• Ukusekela Izivumelwano Ezimbili: Khetha phakathi kwe-SEP (Iphakheji Yokwandisa Isevisi) kanye ne-FSED (Idatha Yokwandisa Isevisi Esisekelwe Kufreyimu). I-SEP ifaka umthwalo omncane kumasistimu endala, kuyilapho i-FSED ithuthukisa ukudluliswa kwevidiyo ephezulu ye-4K/8K.
• Ukulungiswa Okusheshayo: Ama-sensor angashintsha amazinga okuphepha ngesikhathi sangempela – isibonelo, ikhamera ye-drone ingase ivule ukuvikelwa okuphelele uma ithatha izindawo ezivinjelwe futhi yehlise ukuze izindawo zomphakathi.
Le granularity iyashintsha umdlalo kumadivayisi e-IoT, lapho amandla ne-bandwidth kuncishisiwe. Uhlelo lwe-MIPI lunciphisa isikhathi sokulinda esihlobene nokuphepha ngaphezu kuka-40% uma kuqhathaniswa nezixazululo ezijwayelekile zokufihla, ngokwezimfanelo ezivela ku-MIPI Alliance.
4. Ukuhlanganiswa KwezeMisebenzi Zokuphepha Nokuphepha KwezeMidlalo
Ezinhlelweni ezibalulekile zokuphepha, ukuphepha kokusebenza (ukuvimbela ukuwohloka okungafunwa) kanye nokuphepha kwe-cyber (ukuvimbela ukuhlaselwa okubi) kuvame ukuthathwa njengokukhathazeka okuhlukile. I-MIPI ihlanganisa lokhu ngokuhlanganisa izici zokuphepha kokusebenza ezihambisana ne-ISO 26262 nezinyathelo eziqinile zokuphepha kwe-cyber.
Ukuvikelwa Okubambisanayo:
• Cyclic Redundancy Check (CRC) + MAC: I-CRC ibona amaphutha okudluliswa okungafanele (ukuphepha kokusebenza), kanti i-MAC ivimba ukungenelela okwenziwayo (ukuphepha kwe-cyber)
• Ukubheka Isikhathi Sokuphumula: Kuvikela ukuwa kwesistimu ngokwazisa ama-ECU ngama-packet edatha alahlekile – kubalulekile kumasistimu e-ADAS adinga idatha yemvelo yesikhathi sangempela
• Ukuhambisana ne-ASIL: I-MIPI CSE isekela amazinga okuphepha kusuka ku-ASIL B kuya ku-ASIL D, okwenza ifanele konke kusuka kumakhamera e-infotainment kuya ezimotweni ezizimele ngokuphelele.
Le ndawo yokuhlangana iyona ebangela ukuthi abahlinzeki abahamba phambili be-tier-1 bezimoto njenge-Continental ne-Bosch bamukele ama-modules e-MIPI ezinkundleni zabo ze-ADAS zesizukulwane esilandelayo. Ngokubhekana nezingozi eziphawulekayo nezimbi, i-MIPI inciphisa ubunzima besistimu nezindleko zokuhambisana.
5. Ukuqina Kwendawo Yomzimba: Ngaphezu Kwezokuphepha Kwedijithali
Ngenkathi ingxoxo evamile yokuphepha igxile ezinsongweni ze-cyber, izingozi zomphakathi (ukuthambisa, uthuli, izinga lokushisa eliphakeme) zingavala amamojula wekhamera - kudala ubungozi bokuphepha obungaqondile. Amamojula e-MIPI aqhubeka ehlanganisa izici zokuvikela zomzimba ezihambisana nophepha lwawo lwezidijithali.
Izici Zokuphepha Komzimba Ezintsha:
• Ukufakwa Okuphakanyisiwe: Imiklamo epatentiwe efana ne-Senyun Intelligent’s dustproof/waterproof mechanism ivikela izingxenye ze-PCBA ekonakaleni kwemvelo. Lokhu kuqinisekisa ukusebenza okuqhubekayo ezindaweni zezimboni noma ezinhlelweni ze-IoT zangaphandle.
• Izindlu Ezivikelayo: Amamojula ahambisana ne-MIPI ngokuvamile afaka izikhwama ezibonakalayo zokuphula ezivula izaziso zokuphepha uma idivayisi ifinyelelwa ngokomzimba – kubalulekile kumakhamera okuhlola ezindaweni ezisemathubeni aphezulu.
Ngokuhlanganisa ukuphepha kwedijithali nokuphepha komzimba, ama-modules e-MIPI ahlinzeka "ngokuvikela okujulile" okungafani nezithombe ezijwayelekile. Isibonelo, ikhamera yesixeko esihlakaniphile enetekhnoloji ye-MIPI ngeke igcine kuphela imifanekiso ibhalwe, kodwa futhi izokwazi ukumelana nokuphulwa noma nezimo zezulu ezinzima, iqinisekisa ukuvikeleka okungaphazamiseki.
