Google har presenterat<\/a><\/noindex> ett nytt \u00f6ppet projekt OpenTitan<\/a><\/noindex>, vilket \u00e4r en plattform f\u00f6r att skapa betrodda h\u00e5rdvarukomponenter (RoT, Root of Trust). OpenTitan bygger p\u00e5 teknik som redan anv\u00e4nds i kryptografiska USB-token Google Titan<\/a><\/noindex> och TPM-chip<\/a><\/noindex> f\u00f6r att s\u00e4kerst\u00e4lla verifierad uppstart, installerad p\u00e5 servrar inom Googles infrastruktur, samt p\u00e5 Chromebook- och Pixel-enheter. Koden och specifikationerna kopplade till projektet som offentlig dom\u00e4n (<\/a><\/noindex> finns p\u00e5 GitHub under Apache 2.0-licensen.<\/p>\n

Till skillnad fr\u00e5n befintliga implementationer av Root of Trust, utvecklas det nya projektet enligt konceptet \"s\u00e4kerhet genom transparens\", vilket inneb\u00e4r en helt \u00f6ppen utvecklingsprocess och tillg\u00e5ng till kod och scheman. OpenTitan kan anv\u00e4ndas som en f\u00e4rdig, bepr\u00f6vad och p\u00e5litlig ram som m\u00f6jligg\u00f6r \u00f6kad tillit till de l\u00f6sningar som skapas och minskar kostnaderna vid utvecklingen av specialiserade chip f\u00f6r s\u00e4kerhet. OpenTitan kommer att utvecklas p\u00e5 en oberoende plattform som ett samarbetsprojekt, oberoende av specifika leverant\u00f6rer och chipstillverkare. <\/p>\n

Utvecklingen av OpenTitan kommer att \u00f6vervakas av en ideell organisation lowRISC<\/a><\/noindex>, som utvecklar en \u00f6ppen mikroprocessor baserad p\u00e5 RISC-V-arkitekturen. F\u00f6retagen G+D Mobile Security, Nuvoton Technology och Western Digital har redan anslutit sig till det gemensamma arbetet med OpenTitan, liksom ETH Z\u00fcrich och University of Cambridge, vars forskare utvecklar en s\u00e4ker processorarkitektur CHERI<\/a><\/noindex> (Capability Hardware Enhanced RISC Instructions) och nyligen har f\u00e5tt<\/a><\/noindex> ett bidrag p\u00e5 190 miljoner euro f\u00f6r anpassning av relaterad teknik f\u00f6r ARM-processorer och skapandet av en prototyp av den nya h\u00e5rdvaruplattformen Morello.<\/p>\n

OpenTitan-projektet omfattar utvecklingen av olika logiska komponenter som efterfr\u00e5gas i RoT-chip, inklusive en \u00f6ppen mikroprocessor lowRISC Ibex<\/a><\/noindex> baserat p\u00e5 RISC-V-arkitektur, kryptografiska koprocessorer, h\u00e5rdvarugenerator f\u00f6r slumpm\u00e4ssiga tal, hierarkier f\u00f6r lagring av nycklar och data i permanent och tempor\u00e4rt minne, skyddsmekanismer, in- och utmatningsenheter, s\u00e4kra startfunktioner, och s\u00e5 vidare. OpenTitan kan anv\u00e4ndas d\u00e4r det \u00e4r viktigt att s\u00e4kerst\u00e4lla att systemets h\u00e5rdvaru- och programkomponenter befinner sig i ett intakt tillst\u00e5nd, vilket bekr\u00e4ftar att kritiska systemkomponenter inte har blivit manipulerade och baseras p\u00e5 verifierad och tillverkaren auktoriserad kod. <\/p>\n

Chips baserade p\u00e5 OpenTitan kan anv\u00e4ndas i
\nservermoderkort, n\u00e4tverkskort, konsumentenheter, routrar, IoT-enheter f\u00f6r verifiering av firmware (identifiering av firmwaremodifieringar av skadlig programvara), tillhandah\u00e5llande av en kryptografiskt unik systemidentifierare (skydd mot manipulation av h\u00e5rdvara), skydd av kryptografiska nycklar (isolering av nycklar om en angripare f\u00e5r fysisk tillg\u00e5ng till utrustningen), tillhandah\u00e5llande av s\u00e4kerhetsrelaterade tj\u00e4nster och underh\u00e5ll av en isolerad revisionslogg som inte kan redigeras eller raderas.<\/p>\n
