Google pr\u00e6senterede<\/a><\/noindex> et nyt \u00e5bent projekt OpenTitan<\/a><\/noindex>, der fungerer som en platform til at skabe betroede hardwarekomponenter (RoT, Root of Trust). OpenTitan bygger p\u00e5 teknologier, der allerede anvendes i kryptografiske USB-token Google Titan<\/a><\/noindex> og TPM-chips<\/a><\/noindex> for at sikre verficeret opstart, der installeres p\u00e5 servere i Googles infrastruktur samt p\u00e5 Chromebook- og Pixel-enheder. Relateret kode og specifikationer for hardwarekomponenter er offentliggjort<\/a><\/noindex> er tilg\u00e6ngelige p\u00e5 GitHub under Apache 2.0 licensen.<\/p>\n

I mods\u00e6tning til eksisterende implementationer af Root of Trust udvikles det nye projekt i overensstemmelse med konceptet \"sikkerhed gennem gennemsigtighed\", som indeb\u00e6rer en helt \u00e5ben udviklingsproces samt tilg\u00e6ngelighed af kode og diagrammer. OpenTitan kan anvendes som en f\u00e6rdig, testet og p\u00e5lidelig ramme, der g\u00f8r det muligt at \u00f8ge tilliden til de l\u00f8sninger, der udvikles, og at reducere omkostningerne ved udviklingen af specialiserede chips til sikkerhed. OpenTitan vil udvikle sig p\u00e5 en uafh\u00e6ngig platform som et samarbejdsprojekt, der ikke er knyttet til specifikke leverand\u00f8rer og chipproducenter. <\/p>\n

Udviklingen af OpenTitan vil blive styret af en nonprofitorganisation lowRISC<\/a><\/noindex>, der udvikler en fri mikroprocessor baseret p\u00e5 RISC-V-arkitekturen. Virksomheder som G+D Mobile Security, Nuvoton Technology og Western Digital samt Det Tekniske Universitet i Z\u00fcrich og Cambridge University, hvis forskere udvikler en sikker processorarkitektur, er allerede involveret i det f\u00e6lles arbejde med OpenTitan. CHERI<\/a><\/noindex> (Capability Hardware Enhanced RISC Instructions) og for nylig har f\u00e5et<\/a><\/noindex> har f\u00e5et et tilskud p\u00e5 190 millioner euro til tilpasning af relaterede teknologier til ARM-processorer og skabelsen af en prototype af den nye hardwareplatform Morello.<\/p>\n

OpenTitan-projektet d\u00e6kker udviklingen af forskellige logiske komponenter, der er efterspurgt i RoT-chips, herunder den \u00e5bne mikroprocessor lowRISC Ibex<\/a><\/noindex> baseret p\u00e5 RISC-V-arkitektur, kryptografiske co-processorer, hardware tilf\u00e6ldige talgeneratorer, hierarkier til opbevaring af n\u00f8gler og data i ikke-flygtig og flygtig hukommelse, beskyttelsesmetoder, ind- og udgange, sikre opstartsmidler osv. OpenTitan kan bruges der, hvor det er n\u00f8dvendigt at garantere integriteten af hardware- og softwarekomponenterne i systemet, og sikre at kritiske systemkomponenter ikke er blevet \u00e6ndret og bygger p\u00e5 verificeret og autoriseret producentkode. <\/p>\n

Chips baseret p\u00e5 OpenTitan kan bruges i
\nservermoderkort, netv\u00e6rkskort, forbrugerenheder, routere, enheder til internet of things til verifikation af firmware (opdagelse af firmwaremodifikationer af ondsindet software), levering af kryptografisk unikke systemidentifikatorer (beskyttelse mod hardware\u00e6ndringer), beskyttelse af kryptografiske n\u00f8gler (isolation af n\u00f8gler ved fysisk adgang fra en angriber til udstyret), levering af sikkerhedsrelaterede tjenester og opretholdelse af en isoleret revisionslog, der ikke kan redigeres eller slettes.<\/p>\n
