Google har efter sex \u00e5rs arbete med projektet meddelat att produktionen av en chip som \u00e4r baserad p\u00e5 den \u00f6ppna plattformen OpenTitan har inletts. Chipet tillverkas av Nuvoton och marknadsf\u00f6rs som den f\u00f6rsta implementationen av OpenTitan, redo f\u00f6r anv\u00e4ndning i arbetsprojekt. F\u00f6r n\u00e4rvarande har en provbatch sl\u00e4ppts f\u00f6r testning, och starten av massproduktionen \u00e4r planerad till v\u00e5ren i \u00e5r. <\/p>\n

OpenTitan \u00e4r en plattform f\u00f6r att skapa betrodda h\u00e5rdvarukomponenter (RoT, Root of Trust), som anv\u00e4nds d\u00e4r det \u00e4r n\u00f6dv\u00e4ndigt att s\u00e4kerst\u00e4lla det of\u00f6r\u00e4ndrade tillst\u00e5ndet hos systemets h\u00e5rdvaru- och mjukvarukomponenter. Till exempel f\u00f6r att verifiera att kritiska delar av systemet inte har blivit manipulerade och baseras p\u00e5 verifierad och godk\u00e4nd kod fr\u00e5n tillverkaren. Projektet erbjuder en f\u00e4rdig, verifierad och p\u00e5litlig ram som m\u00f6jligg\u00f6r att \u00f6ka f\u00f6rtroendet f\u00f6r de l\u00f6sningar som utvecklas och minska kostnaderna f\u00f6r utveckling av specialiserade chip f\u00f6r s\u00e4kerhets\u00e4ndam\u00e5l. <\/p>\n

Chips baserade p\u00e5 OpenTitan kan anv\u00e4ndas i servermoderkort, n\u00e4tverkskort, konsumentenheter, routrar och IoT-enheter f\u00f6r verifiering av firmware och nedladdade komponenter, f\u00f6r att generera kryptografiskt unika systemidentifierare (skydd mot h\u00e5rdvarumanipulation), f\u00f6r att tillhandah\u00e5lla s\u00e4kerhetsrelaterade tj\u00e4nster, f\u00f6r att skydda kryptografiska nycklar (isolering av nycklar vid fysisk \u00e5tkomst till utrustningen av en angripare) och f\u00f6r att skapa en isolerad revisionslogg som inte kan redigeras eller raderas. <\/p>\n

OpenTitan inkluderar logiska block som efterfr\u00e5gas i RoT-chips, s\u00e5som en \u00f6ppen mikroprocessor baserad p\u00e5 RISC-V-arkitekturen (RV32IMCB Ibex), kryptografiska coprocessorer, en h\u00e5rdvarugenerator f\u00f6r slumpm\u00e4ssiga tal, en nyckelhanterare med DICE-st\u00f6d, en mekanism f\u00f6r s\u00e4ker lagring av data i icke-flyktigt och flyktigt minne, skyddsteknologier, I\/O-block och komponenter f\u00f6r s\u00e4ker uppstart. Enheten tillhandah\u00e5ller ocks\u00e5 block med implementation av standardiserade krypteringsalgoritmer, s\u00e5som AES och HMAC-SHA256, samt en accelerator f\u00f6r matematiska operationer som till\u00e4mpas i algoritmer f\u00f6r digitala signaturer baserade p\u00e5 \u00f6ppna nycklar.

Projektet grundades av Google, men \u00f6verl\u00e4mnades till den ideella organisationen lowRISC, efter vilket f\u00f6retag som Western Digital, Seagate, Nuvoton Technology, Winbond, Rivos, zeroRISC och G+D Mobile Security ansl\u00f6t sig till dess utveckling. Den relaterade koden och specifikationerna f\u00f6r h\u00e5rdvarukomponenterna publicerades under Apache 2.0-licensen. De l\u00f6sningar som anv\u00e4nds i OpenTitan bygger p\u00e5 teknologier som redan anv\u00e4nds i Googles Titan-kryptografiska USB-token och TPM-chips f\u00f6r att s\u00e4kerst\u00e4lla verifierad uppstart. servrar<\/a> Google-infrastrukturen s\u00e5v\u00e4l som p\u00e5 Chromebook- och Pixel-enheter. <\/p>\n

Till skillnad fr\u00e5n befintliga implementeringar av Root of Trust utvecklas OpenTitan utifr\u00e5n konceptet \"s\u00e4kerhet genom transparens\", vilket innefattar tillg\u00e5ng till k\u00e4llkod och scheman samt anv\u00e4ndning av en helt \u00f6ppen utvecklingsprocess som inte \u00e4r kopplad till specifika leverant\u00f6rer och chipstillverkare. OpenTitan blev den f\u00f6rsta \u00f6ppna implementeringen av Root of Trust som sl\u00e4ppts p\u00e5 marknaden, som har st\u00f6d f\u00f6r en post-kvant s\u00e4ker boot-mekanism baserad p\u00e5 anv\u00e4ndningen av algoritmen f\u00f6r digitala signaturer SLH-DSA (Sphincs+), vilket \u00e4r motst\u00e5ndskraftigt mot kvantdatorattacker.
