Google har annonceret, at de vil begynde at bruge chips bygget p\u00e5 den \u00e5bne platform OpenTitan i Chromebook-enheder. Chromebook er blevet de f\u00f8rste kommercielt tilg\u00e6ngelige enheder, der er udstyret med OpenTitan. I \u00e5r planl\u00e6gger Google at implementere server systemer med OpenTitan i deres datacentre. Masseproduktion af chipsene er organiseret af Nuvoton. Det er ogs\u00e5 blevet bem\u00e6rket, at arbejdet med en ny version af chippen er begyndt, som vil muligg\u00f8re brugen af post-kvantum algoritmerne ML-DSA og ML-KEM til sikker opstart og validering, der implementerer kryptografiske metoder baseret p\u00e5 l\u00f8sning af gitterteoretiske problemer.

OpenTitan-projektet tilbyder en platform til udvikling af betroede hardwarekomponenter (RoT, Root of Trust), der anvendes der, hvor der er behov for at garantere den integrerede tilstand af hardware- og softwareelementer i systemet. OpenTitan blev grundlagt af Google i 2018, men blev i 2019 overf\u00f8rt til den non-profit organisation lowRISC, hvorefter virksomheder som Western Digital, Seagate, Nuvoton Technology, Winbond, Rivos, zeroRISC og G+D Mobile Security sluttede sig til udviklingen. Koden og specifikationerne til hardwarekomponenterne relateret til projektet er blevet offentliggjort under Apache 2.0 licensen. De l\u00f8sninger, der anvendes i OpenTitan, bygger p\u00e5 teknologier, der allerede anvendes i Googles Titan kryptografiske USB-tokens og TPM-chips til at sikre valideret opstart, installeret p\u00e5 servere<\/a> infrastrukturen i Google, samt p\u00e5 Chromebook- og Pixel-enheder. <\/p>\n

I mods\u00e6tning til eksisterende implementeringer af Root of Trust udvikler OpenTitan sig i overensstemmelse med konceptet \u00bbsikkerhed gennem gennemsigtighed\u00ab, hvilket indeb\u00e6rer tilg\u00e6ngelighed af kode og skemaer samt anvendelse af en helt \u00e5ben udviklingsproces, der ikke er knyttet til specifikke leverand\u00f8rer og chipproducenter. OpenTitan er blevet den f\u00f8rste \u00e5bne implementering af Root of Trust, der er lanceret p\u00e5 markedet, og som har st\u00f8tte til en post-kvantemekanisme for sikker opstart, baseret p\u00e5 brugen af SLH-DSA (Sphincs+) digital signaturalgoritmen, der er modstandsdygtig over for kvantecomputerangreb. <\/p>\n

OpenTitan-baserede chips kan anvendes i serverbundkort, netv\u00e6rkskort, forbrugerudstyr, routere og IoT-enheder til verifikation af firmware og indl\u00e6ste komponenter (beskyttelse mod \u00e6ndring af kritiske systemdele), til at generere kryptografisk unikke systemidentifikatorer (beskyttelse mod udskiftning af hardware), til at tilbyde sikkerhedsrelaterede tjenester, til at beskytte kryptografiske n\u00f8gler (isolering af n\u00f8gler i tilf\u00e6lde af at en angriber f\u00e5r fysisk adgang til udstyret) samt til at f\u00f8re en isoleret revisionslog, der ikke kan redigeres eller slettes. <\/p>\n

OpenTitan omfatter logiske blokke, der er eftertragtede i RoT-chips, s\u00e5som en \u00e5ben mikroprocessor baseret p\u00e5 RISC-V-arkitekturen (RV32IMCB Ibex), kryptografiske co-processorer, en hardware-random number generator, en n\u00f8gleadministrator med DICE-support, en mekanisme til sikker datalagring i permanent og RAM, beskyttelsesteknologier, input\/output-enheder og komponenter til sikker opstart. Enheden tilbyder ogs\u00e5 blokke med implementering af standardiserede krypteringsalgoritmer som AES og HMAC-SHA256 samt en accelerator til matematiske operationer, der anvendes i algoritmer til arbejde med digitale signaturer baseret p\u00e5 offentlige n\u00f8gler. <\/p>\n
