  • I-OpenTitan iphrojekthi ye-silicon yomthombo ovulekile esebenza njengempande yokuthembela.
  • Ihlinzeka ngokuvikeleka nokungafihli ku-hardware yamaseva, i-IoT nezinhlelo zokusebenza zezimboni.
  • Idizayini yayo evulekile ivumela ukucwaningwa kwamabhuku nokuzivumelanisa nezimo ngaphandle kwemikhawulo yamalayisensi okuphathelene.
  • Inikwa amandla i-Google, i-lowRISC nabanye ozakwethu ukuqinisa ukuphepha kwekhompyutha.

I-Silicon ye-OpenTitan

I-OpenTitan iphrojekthi yokuqala ye-silicon evulekile eyenzelwe ukusebenza njenge- Umsuka Wokuthenjwa (RoT) kuwo wonke amadivaysi anhlobonhlobo, kusuka kumaseva kuya kumadivayisi we-IoT. Umgomo wayo ukuhlinzeka ngesisekelo se-hardware esivikelekile nesihloliwe, okwandisa obala y ukuphepha ye-ecosystem yezobuchwepheshe.

Le phrojekthi entsha iye yathuthukiswa ngokubambisana nezinhlangano ezifana -Google, lowRISC kanye namanyuvesi amaningana, ngenhloso yokunciphisa ukuncika ezixazululweni zokuphathelene nokunikeza okwengeziwe nakanjani ezindaweni ezibucayi.

Iyini i-OpenTitan futhi isetshenziselwa ini?

I-OpenTitan Kuyinto a iphrojekthi yehadiwe yomthombo ovulekile okunikeza isethi yamathuluzi kanye nokucaciswa kokuklama ama-chips okuvikela asebenza njengempande yokuthembana. Umsebenzi wawo oyinhloko ukuqinisekisa ukuthi isistimu iqala futhi isebenza kahle. nakanjani, eqinisekisa ubuqotho be- isofthiwe futhi i hardware kusukela ekuqaleni.

Izimpande zokwethembana zibalulekile ekuvikelekeni kwe-inthanethi njengoba zivimbela ukuhlaselwa okufana nokuphazanyiswa kwe-firmware ngokuqinisekisa ukuthi isofthiwe eqinisekisiwe kuphela ekwazi ukufinyelela emisebenzini yesistimu ebalulekile. I-OpenTitan ifuna ukunweba leli zinga lokuvikeleka kumapulatifomu ahlukahlukene ngenxa yokufinyeleleka kwayo nokungafihli lutho.

Izici ezibalulekile ze-OpenTitan

Ngokungafani nempande yendabuko yezixazululo zokuthembela, i-OpenTitan isuselwe kulezi zimiso ezibalulekile ezilandelayo:

  • Ukukhanyela okuphelele: Njengomthombo ovulekile, noma yimuphi umuntu noma inkampani ingakwazi hlola, cwaninga futhi uthuthukise ukwakheka kwayo.
  • Ikhwalithi ephezulu: Ukuthuthuka kwayo kulandela izinqubo ezinzima ze ukuqinisekiswa kanye nezivivinyo zokuqinisekisa ukuphepha kanye nokwethembeka.
  • Ukuvumelana nezimo: Kungenziwa ingashintshwa ukuze ezisekelweni ezahlukene kanye nezidingo ngaphandle kokuba kunqunyelwe kumphakeli oyedwa.
  Ukuhambisana kwe-cache kuma-CPU amaningi: ukuthi igcinwa kanjani nokuthi ubani oyilawulayo

Umlando nokuthuthukiswa kwe-OpenTitan

Iphrojekthi ye-OpenTitan yaqala ngo-2018 njengesinyathelo se-Google ne-lowRISC, kanye nabanye abahlanganyeli abavela kwezemfundo nezimboni. Umgomo wabo kwakuwukwenza a Isixazululo esithembekile sehadiwe ezingase zisetshenziswe engqalasizinda yezobuchwepheshe yezinkampani ezinkulu nezikhungo zedatha.

Ngo-2019, iphrojekthi yethulwa ngokusemthethweni ngokusekelwa yi-ETH Zürich, Nuvoton Technology, G+D Mobile Security, Western Digital nabanye ozakwethu. Kusukela lapho, i-OpenTitan ithole ukukhula okuqhubekayo, ukwandisa umphakathi wayo kanye nokucwenga umklamo wayo ukuze uzuze amazinga ekhwalithi yezohwebo.

Muva nje, kumenyezelwe ukuthi ukukhiqizwa kweyokuqala ama-chips okukhiqiza isiqalile, okumaka ingqophamlando ebalulekile ekuhlanganiseni i-OpenTitan njengesixazululo esisebenzayo emakethe.

Izinzuzo ze-OpenTitan ngaphezu kwezixazululo zokuphathelene

Izixazululo zokuphepha zehadiwe zobunikazi zinikeza ukusebenza okuhle, kodwa ngokuvamile zinemikhawulo ethile, njengokuthi ukungabi sobala kanye nokuncika kumphakeli oyedwa. I-OpenTitan ixazulula lezi zinkinga ngokunikeza:

  • Ukubonakala okukhulu: Njengomthombo ovulekile, noma ubani angabheka ikhodi futhi aphakamise ukuthuthukiswa.
  • Izindleko eziphansi nokutholwa okukhulu: Ukufinyeleleka kwayo kuvumela izimboni eziningi ukuthi ziyihlanganise ngaphandle kwemikhawulo yamalayisensi.
  • Ukuvikeleka Okuthuthukisiwe: Ivumela ukucwaningwa kwamabhuku okuqhubekayo komphakathi, kunciphisa ubungozi.

I-OpenTitan Sebenzisa Amacala Nezicelo

I-OpenTitan yakhelwe ukuthi isetshenziswe ku-a anhlobonhlobo amasistimu, kufaka phakathi:

  • Amaseva nezikhungo zedatha: Ukuthuthukisa ukuphepha kwingqalasizinda yokugcina amafu.
  • I-IoT namadivayisi ashumekiwe: Ukuqinisekisa ukuthi amadivayisi omthengi aqala isofthiwe enokwethenjelwa.
  • Amasistimu wezimboni: Ukuvikelwa ekuhlaselweni ngokomzimba noma ukuxhashazwa kwehadiwe.
  • Amakhompyutha namafoni: Ukuhlanganiswa ezinkundleni zabathengi ukuze a ukuphepha iqine kakhudlwana.

Ukwengeza, idizayini yayo eguquguqukayo ivumela izinkampani ukuthi zenze ngokwezifiso ukuqaliswa ukuze kuhambisane nezidingo zabo ezithile.

Intuthuko ye-OpenTitan embonini ye-cybersecurity imele isinyathelo esibalulekile sokwethenjwa okukhulu nokusobala kuhadiwe. Imvelo yayo yomthombo ovulekile iyenza ibe inketho ekhangayo kumabhizinisi afuna umsuka wokwethembana ongaxhumene nezixazululo zobunikazi. Ngokutholwa kwayo okukhulayo nokusekelwa kwabadlali ababalulekile bemboni, i-OpenTitan ithembisa ukuguqula isimo sokuphepha se-silicon.
