Den ideella organisationen lowRISC, som \u00f6vervakar utvecklingen av en \u00f6ppen mikrokprocessor baserad p\u00e5 RISC-V-arkitekturen, har meddelat att den f\u00f6rsta chippet som \u00e4r klart f\u00f6r kommersiell produktion, byggt p\u00e5 den \u00f6ppna plattformen OpenTitan, nu \u00e4r tillg\u00e4ngligt. Projektet initierades av Google, men efter att ha \u00f6verl\u00e5tits till lowRISC har f\u00f6retag som Western Digital, Seagate, Nuvoton Technology, Winbond, Rivos, zeroRISC och G+D Mobile Security anslutit sig till dess utveckling. Koden och specifikationerna f\u00f6r h\u00e5rdvarukomponenterna relaterade till projektet publicerades under Apache 2.0-licensen. <\/p>\n

Till skillnad fr\u00e5n befintliga implementeringar av Root of Trust utvecklas OpenTitan enligt konceptet \"s\u00e4kerhet genom transparens\", vilket inneb\u00e4r tillg\u00e5ng till koden och scheman, samt en helt \u00f6ppen utvecklingsprocess som inte \u00e4r knuten till specifika leverant\u00f6rer och chipstillverkare. Grunden f\u00f6r de l\u00f6sningar som anv\u00e4nds i OpenTitan \u00e4r teknologier som redan anv\u00e4nds i Googles Titan-kryptografiska USB-token och TPM-chip f\u00f6r att s\u00e4kerst\u00e4lla verifierad uppstart, som installeras p\u00e5 servrar<\/a> Google-infrastrukturen s\u00e5v\u00e4l som p\u00e5 Chromebook- och Pixel-enheter. <\/p>\n

OpenTitan \u00e4r en plattform f\u00f6r att skapa p\u00e5litliga h\u00e5rdvarukomponenter (RoT, Root of Trust) som kan anv\u00e4ndas d\u00e4r det \u00e4r n\u00f6dv\u00e4ndigt att garantera det of\u00f6r\u00e4ndrade tillst\u00e5ndet f\u00f6r systemets h\u00e5rdvara och programvara, vilket s\u00e4kerst\u00e4ller att kritiska delar av systemet inte har blivit ersatta och baseras p\u00e5 verifierad och tillverkarsanktionerad kod. Projektet erbjuder en f\u00e4rdig, testad och p\u00e5litlig ram, vilket \u00f6kar f\u00f6rtroendet f\u00f6r de l\u00f6sningar som skapas och s\u00e4nker kostnaderna vid utveckling av specialiserade chip f\u00f6r s\u00e4kerhet. <\/p>\n

Chips baserade p\u00e5 OpenTitan kan anv\u00e4ndas i servermoderkort, n\u00e4tverkskort, konsumentenheter, routrar och Internet of Things-enheter f\u00f6r att verifiera firmware och laddade komponenter, samt f\u00f6r att generera kryptografiskt unika systemidentifierare (skydd mot utrustningsmanipulation), skydda kryptografiska nycklar (isolering av nycklar om en angripare f\u00e5r fysisk \u00e5tkomst till utrustningen), tillhandah\u00e5lla s\u00e4kerhetsrelaterade tj\u00e4nster och h\u00e5lla en isolerad revisionslogg som inte kan redigeras eller raderas. <\/p>\n

OpenTitan inkluderar olika logiska block som efterfr\u00e5gas i RoT-chips, s\u00e5som en \u00f6ppen mikroprocessor byggd p\u00e5 RISC-V-arkitektur (RV32IMCB Ibex), kryptografiska koprocessorer, en h\u00e5rdvarugenerator f\u00f6r slumpm\u00e4ssiga tal, en nyckelhanterare med DICE-st\u00f6d, en mekanism f\u00f6r s\u00e4ker datalagring i icke-flygande och flygande minne, skyddstekniker, I\/O-block, s\u00e4kra startl\u00f6sningar osv. Enheten tillhandah\u00e5ller \u00e4ven block med implementationer av standardkrypteringsalgoritmer som AES och HMAC-SHA256 samt en accelerator f\u00f6r matematiska operationer som anv\u00e4nds i algoritmer f\u00f6r att arbeta med digitala signaturer baserade p\u00e5 offentlig nyckel, s\u00e5som RSA och algoritmer baserade p\u00e5 elliptiska kurvor.
