Muva nje kwaqhamuka izindaba zokuthi iGoogle isebenzisane nezinkampani eziningana kwezobuchwepheshe ukuthuthukisa ama-chip womthombo ophephile futhi ovulekile. Inhloso yomfelandawonye omusha ukudala ukwakheka kwe-chip Iqinile ekusetshenzisweni ezikhungweni zedatha, kumaseva nemingcele efakwe ezindaweni ezibucayi.
Iphrojekthi ibizwa nge-OpenTitan, uhlelo lomthombo ovulekile olwakhiwe ukukhuthaza ukuthuthukiswa kobuchwepheshe obubizwa nge-Root of Trus (ROT). izikhungo zedatha namadivayisi wabathengi. Le nkampani ihlose ukuyisebenzisa kuma-smartphones ayo asuselwa ku-Android, kanye nakumadivayisi wezokuphepha wehadiwe ahlukile.
AbakwaGoogle bakusho lokho I-OpenTitan izophathwa ngumphakathi we-LowRisc. Ozakwethu bahlanganisa i-ETH Zurich, i-G + D Mobile Security, i-Nuvoton Technology, ne-Western Digital.
Ngesikhathi esifanayo, Ikhono lokuvumelanisa i-OpenTitan cishe kunoma iyiphi idivayisi noma isoftware lifunwa. Uma isistimu ichazwa njengene-ROT, kusho ukuthi kune-chip ekhethekile noma imojuli ebhekele ukuvimba imizamo yokugebenga.
Ocingweni olwedluleI-Google Pixel 4, isibonelo, i-Titan M microcontroller idlala leyo ndima. Yiprosesa encane eqinisekisa ubuqotho be-firmware ezingcingweni zabasebenzisi njalo lapho ivuliwe.
Okwamanje, ezikhungweni zedatha, I-ROT ivame ukwaziwa njengemojula yokuphepha yehadiwe, idivayisi ezinikele 'evikela' okhiye bokubethela lapho amaseva abhala ngemfihlo imininingwane eyimfihlo. Amamojula okuphepha we-Hardware ahlukanisiwe nayo yonke inethiwekhi futhi imvamisa iza ngecala eliphikisayo.
Nge-OpenTitan, i-Google inethemba lokuhlinzeka imboni ngamabhulokhi wokwakha ubuchwepheshe obufanayo ukuze idale imikhiqizo ye-Root of Trus.
Isikhondlakhondla sosesho okwamanje ithuthukisa idizayini chip eklanyelwe ngokukhethekile wephrojekthi usebenzisa ukwakheka kwe-RISC-V okudumile. Kunezinye izinto eziningi nasemisebenzini, kufaka phakathi i-firmware, ama-coprocessors alungiselelwe ukuphatha imisebenzi ye-cryptographic, kanye ne-generator yenombolo engahleliwe yokwakha okhiye bokubethela.
«Ama-chip womthombo ovulekile angathuthukisa ukwethembana nokuphepha ngokwakhiwa nokusebenza okusobala »
"Izinkinga zingasheshe zitholakale futhi nesidingo sokuthembana singaboni siyancipha." Bangeze ukuthi ukuhlanganyela ngokukhululekile ubuchwepheshe obuyisisekelo "kungavumela futhi kukhuthaze ukusungulwa okusha ngeminikelo yokuvula ukwakhiwa kwemithombo." Wabhala u-Royal Hansen, Isikhulu sezokuphepha kolwazi kwaGoogle kanye nomholi we-OpenTitan uDominic Rizzo eposini le-blog.
I-Google isebenza ngenkuthalo ukuheha i-ecosystem yabanikeli. Le nkampani idlulisele ukuphathwa kwe-OpenTitan kwaLowRisc, okuyinhlangano yezimboni ehlangene ne-University of CambridgEy iqasha abalingani bangaphandle ukuxhasa intuthuko.
UHansen noRizzo babhala lokho ubuchwepheshe obukhiqizwa nge-OpenTitan buzoba
"Isebenzisela abenzi be-chipmakers abaqaphela ukuphepha, abahlinzeka ngamapulatifomu, nezinhlangano zamabhizinisi ezifuna ukuthuthukisa ingqalasizinda yazo."
Noma ibuphi ubuchwepheshe lezo zinhlangano ezinikela ngazo ku-OpenTitan bungaba usizo ku-Google. Inkampani isebenzisa ama-chips e-Root of Trus kumafoni ayo e-Pixel, ithebhulethi ye-Pixel Slate futhi okubaluleke kakhulu, ezikhungweni zayo zedatha ukuvikela amaseva ekuhlaselweni.
Isithembiso sama-chip ezokuphepha asebenza kangcono singalinga ezinye izimbangi I-Google ijoyine i-OpenTitan.
I-Apple Inc. ngokwesibonelo inephrosesa yayo ye-Root of Trus ebizwa nge-T2 enamamodeli athile e-Mac, kuyilapho i-Amazon Web Services Inc. ihlinzeka ngemisebenzi yemojula yokuphepha yezingxenyekazi zekhompuyutha ngeplathifomu yayo yamafu.
Ngokwengxenye yayo, isebenzisa isikhundla sayo kwingqalasizinda yedatha nakubuchwepheshe bemithombo evulekile, I-Western Digital isebenza nabalingani be-ecosystem ukwenza ngcono uhlaka lwe-OpenTitan ukuhlangabezana nezidingo zokuphepha ezahlukahlukene zamacala wokusebenzisa wedatha wokugcina wedatha, kufaka phakathi izinhlelo zokusebenza zokufunda ngomshini, ama-Smartphones, kanye ne-Intanethi Yezinto (IoT) ezixhunyiwe.
Imininingwane engaphezulu ngayo, kulesi sixhumanisi.
Enye yezinhloso ezinkulu zeGoogle zale phrojekthi ukuthuthukisa ama-chip avimba "ngokomzimba" isoftware efakwe ocingweni noma ukuthi abantu bangafaka ama-firmwares abo noma ama-roms abo.
Ama-chips emithombo evulekile angumbono omuhle ongawusiza kakhulu umphakathi, kepha masingakhohliswa yi-giant nezinhloso zayo.
