Google har efter seks \u00e5rs arbejde med projektet annonceret, at produktionen af en chip baseret p\u00e5 den \u00e5bne platform OpenTitan er begyndt. Chippen produceres af Nuvoton og er markeret som den f\u00f8rste implementering af OpenTitan, der er klar til brug i arbejdsprojekter. I \u00f8jeblikket er der blevet udgivet en testbatch til test, og masseproduktionen er planlagt til at starte i for\u00e5ret i \u00e5r. <\/p>\n

OpenTitan er en platform til udvikling af p\u00e5lidelige hardware-komponenter (RoT, Root of Trust), der anvendes der, hvor det er n\u00f8dvendigt at garantere integriteten af systemets hardware- og softwareelementer. For eksempel for at sikre, at systemets kritisk vigtige dele ikke er blevet \u00e6ndret og baseres p\u00e5 godkendt og verificeret kode fra producenten. Projektet tilbyder et klart, verificeret og p\u00e5lideligt rammev\u00e6rk, der g\u00f8r det muligt at \u00f8ge tilliden til de udviklede l\u00f8sninger og reducere omkostningerne ved udvikling af specialiserede chips til sikkerhed. <\/p>\n

Chips baseret p\u00e5 OpenTitan kan anvendes i serverbundkort, netv\u00e6rkskort, forbrugerudstyr, routere og Internet of Things-enheder til verifikation af firmware og indl\u00e6ste komponenter, til at generere kryptografisk unikke systemidentifieringer (beskyttelse mod udskiftning af hardware), til at tilbyde sikkerhedsrelaterede tjenester, til at beskytte kryptografiske n\u00f8gler (isolation af n\u00f8gler i tilf\u00e6lde af, at en angriber f\u00e5r fysisk adgang til udstyret) og til at f\u00f8re en isoleret revisionslog, som 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.

Projektet blev grundlagt af Google, men blev overdraget til den ideelle 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 for hardwarekomponenterne relateret til projektet er offentliggjort under Apache 2.0-licensen. L\u00f8sningerne, der anvendes i OpenTitan, er baseret p\u00e5 teknologier, der allerede anvendes i Googles Titan kryptografiske USB-tokens og TPM-chips til verificeret boot, der installeres 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.
