Den non-profit organisation lowRISC, der koordinerer udviklingen af en fritst\u00e5ende mikroprocessor baseret p\u00e5 RISC-V arkitekturen, har annonceret tilg\u00e6ngeligheden af den f\u00f8rste chip klar til kommerciel produktion, bygget p\u00e5 den \u00e5bne platform OpenTitan, som udvikles som et uafh\u00e6ngigt samarbejdsprojekt. Projektet blev oprindeligt grundlagt af Google, men efter overdragelsen til lowRISC har virksomheder som Western Digital, Seagate, Nuvoton Technology, Winbond, Rivos, zeroRISC og G+D Mobile Security sluttet sig til udviklingen. Den relaterede kode og specifikationer for hardwarekomponenter er offentliggjort under Apache 2.0 licensen. <\/p>\n

I mods\u00e6tning til eksisterende implementeringer af Root of Trust udvikles OpenTitan i overensstemmelse med konceptet \"sikkerhed gennem gennemsigtighed\", hvilket indeb\u00e6rer tilg\u00e6ngelighed af kode og skemaer samt en fuldst\u00e6ndig \u00e5ben udviklingsproces, der ikke er knyttet til specifikke leverand\u00f8rer og chipproducenter. Grundlaget for de l\u00f8sninger, der anvendes i OpenTitan, bygger p\u00e5 teknologier, der allerede anvendes i Googles kryptografiske USB-tokens Titan og TPM-chips til at sikre verifikation af opstart, der installeres p\u00e5 servere<\/a> infrastrukturen i Google, samt p\u00e5 Chromebook- og Pixel-enheder. <\/p>\n

OpenTitan er en platform til opbygning af p\u00e5lidelige hardwarekomponenter (RoT, Root of Trust), der kan anvendes der, hvor det er n\u00f8dvendigt at sikre det korrekte tilstand af systemets hardware- og softwareelementer, og bekr\u00e6fte, at kritiske dele af systemet ikke er blevet manipuleret og baseres p\u00e5 verificeret og autoriseret kode fra producenten. Projektet leverer et klart, bevist og p\u00e5lideligt fundament, der g\u00f8r det muligt at \u00f8ge tilliden til de udviklede l\u00f8sninger og reducere omkostningerne ved udviklingen af specialiserede chips til sikkerhed. <\/p>\n

Chips baseret p\u00e5 OpenTitan kan anvendes i servermodermoduler, netv\u00e6rkskort, forbrugerprodukter, routere og Internet of Things-enheder til at verificere firmware og downloadede komponenter samt til at generere kryptografisk unikke systemidentifikatorer (beskyttelse mod hardwareforfalskning), beskytte kryptografiske n\u00f8gler (isolering af n\u00f8gler, hvis en angriber f\u00e5r fysisk adgang til udstyret), tilbyde sikkerhedsrelaterede tjenester og f\u00f8re en isoleret revisionslog, som ikke kan redigeres eller slettes. <\/p>\n

OpenTitan inkluderer forskellige logiske blokke, som er eftertragtede i RoT-chips, s\u00e5som en open-source mikroprocessor baseret p\u00e5 RISC-V-arkitektur (RV32IMCB Ibex), kryptografiske co-processorer, en hardware-random number generator, en n\u00f8glemanager med DICE-support, en mekanisme til sikker datalagring i non-volatile og volatile hukommelse, beskyttelsesteknologier, input\/output-enheder, v\u00e6rkt\u00f8jer til sikker opstart osv. Enheden tilbyder ogs\u00e5 blokke med implementering af standard krypteringsalgoritmer, s\u00e5som AES og HMAC-SHA256, samt en accelerator til matematiske operationer anvendt i algoritmer til digital signaturbehandling baseret p\u00e5 offentlige n\u00f8gler, s\u00e5som RSA og algoritmer baseret p\u00e5 elliptiske kurver.
