Google yakaratidza chirongwa chakavhurika sosi "OpenTitan", kugadzira machipisi akachengeteka uye akavimbika

Mamwe mazuva apfuura Google yakaratidza chirongwa chitsva chakavhurwa, rine zita "OpenTitan " uye izvo zvinotsanangura kuti sei chikuva chekugadzira zvakavimbika zvigadzirwa zvehardware (RoT, Mudzi weTrust). OpenTitan inovaka pamatekinoroji akato shandiswa muGoogle Titan crypto USB tokeni uye TPM machipisi ekupa kudzoreredzwa kurodha pasi kunoiswa pamaseva pane zvivakwa zveGoogle, pamwe neChannelbook nePixel zvishandiso.

G + D Nhare Dziviriro, Nuvoton Technology neWestern Digital vakatopinda mubatanidzwa weOpenTitanuyewo mukati iyo Zurich Yakakwira Tekinoroji Chikoro uye iyo Yunivhesiti yeCambridge, iyo vaongorori vari kuvandudza zvivakwa yakachengeteka processorCHERI (Inogonesa Hardware Inowedzeredzwa RISC Mirayiridzo) uye munguva pfupi yapfuura akagamuchira rubatsiro rwemamirioni zana nemamiriyoni euros ekugadzirisa matekinoroji ane chekuita nemaARM mapurosesa uye kugadzira prototypes yeiyo nyowani Morello Hardware chikuva.

Chinangwa chemubatanidzwa mutsva kugadzira zvakavimbika chip dhizaini yekushandisa munzvimbo dzekuchengetedza, kuchengetedza uye komputa zvigadzirwa, izvo zvakavhurika uye zvakajeka, zvichibvumira chero munhu kuti aongorore Hardware yekuchengetedzeka kwekuchengetedza uye kumashure.

Nezve OpenTitan

Kusiyana nepo iriko Midzi yeTrust inoitwa, chirongwa chitsva iri kuvandudzwa zvinoenderana nepfungwa yekuti 'chengetedzo kubudikidza pachena', izvo zvinoreva kuti yakavhurika yakavandudzwa nzira yekuvandudza uye kuwanikwa kwekodhi uye schematics.

OpenTitan inogona kushandiswa senzira yakagadzirira, yakaedzwa uye yakavimbika izvo zvinokutendera iwe kuti uwedzere kuvimba mune mhinduro dzakagadzirwa uye kudzikisa mutengo nekugadzira yakasarudzika machipisi ekuchengetedza. OpenTitan se ichavandudza papuratifomu yakazvimirira seyakabatanidzwa chirongwa, isina kusungirirwa kune chaiyo chip vatengesi uye vagadziri.

"Google payakatanga kuona indasitiri ichida dhizaini yakavhurika, taiziva kuti zvaizoda maneja wechitatu-bato senge lowRISC kukurudzira chirongwa chakavhurika munharaunda," akadaro Dominic Rizzo, mutungamiri weGoogle OpenTitan.

OpenTitan ichave inotarisirwa neasina-purofiti sangano rakadzikaRISC, iyo iri kugadzira yemahara microprocessor yakavakirwa pane RISC-V yekuvakisa.

Iyo OpenTitan chirongwa chinofukidza kuvandudzwa kwemhando dzakasiyana dzepfungwa inodaidzwa muRTT machipisi, kusanganisira yakadereraRISC Ibex yakavhurika microprocessor yakavakirwa paRISC-V mapurani, cryptographic macrocessors, Hardware isina nhamba manhamba jenareta, yenguva dzose uye yakasarudzika yekuwana memory data uye yakakosha yekuchengetedza hutongi, nzira dzekuchengetedza, I / O mabheji ekuisa, akachengeteka midhiya midhiya, nezvimwe.

OpenTitan inogona kushandiswa pazvinodikanwa kuve nechokwadi chekuvimbika kwe Hardware uye software zvikamu zvehurongwa, kuona kuti yakakosha system system haina kutsiviwa uye yakavakirwa pane kodhi yakasimbiswa uye yakapihwa mvumo nemugadziri.

Chips zvichibva pa OpenTitan inogona kushandiswa mu server mamaboards, makadhi enetiweki, zvishandiso zvevatengi, mairaira, Internet yezvinhu zvishandiso kuti uone firmware (tsvaga firmware kugadziridzwa nemarware), ipa cryptographically yakasarudzika system identifier (Hardware yekunyepedzera dziviriro), uye chengetedza Cryptographic makiyi (kiyi yekuzviparadzanisa mune chiitiko icho anorwisa anowana mukana wemuviri kumakomputa), inopa masevhisi ane chekuita nekuchengetedza, uye inochengetedza nzira yakasarudzika yekuongorora isingagadziriswe kana kudzimwa.

OpenTitan mainjiniya parizvino ari kuvaka iyo logic dhizaini yesilicon RoT. Parizvino izvo zvinosanganisira yakavhurwa sosi microprocessor (lowRISC Ibex, dhizaini yakavakirwa paRISC-V), cryptographic macrocessors, Hardware yakasarudzika manhamba jenareta, yakasarudzika kiyi hutungamiriri, ndangariro nhanho dzekuchengetera uye kusingachinjiki kuchengetedza, maitiro ekudzivirira, eIPI yekupararira , chengetedza bhuti uye nezvimwe.

Unogona tarisa kufambira mberi paGitHub seye kodhi-inoenderana nekodhi kodhi uye zvigadzirwa zvehardware zvakatsikiswa paGitHub pasi peiyo Apache 2.0 rezinesi.
