Virksomhederne Google, AMD, NVIDIA og Microsoft har i f\u00e6llesskab udviklet en \u00e5ben designblok til mikrochips (IP-blok) til integrering i chips til at skabe betroede hardwarekomponenter (RoT, Root of Trust) i rammerne af projektet Caliptra. Caliptra er en s\u00e6rskilt hardwareblok med sin egen hukommelse, processor og implementering af kryptografiske primitter, som sikrer verifikation af opstartprocessen, de brugte firmware og den konfiguration, der gemmes i non-volatile hukommelse. <\/p>\n

Caliptra kan anvendes til integration i forskellige chips af en uafh\u00e6ngig hardwareblok, der udf\u00f8rer integritetstjek og garanterer, at der i enheden anvendes godkendt og autoriseret firmware fra producenten. Caliptra kan betydeligt forenkle og standardisere integrationen af indbyggede hardwaremekanismer til kryptografisk verifikation i CPU'er, GPU'er, SoC'er, ASIC'er, netv\u00e6rksadaptere, SSD'er og andet udstyr. <\/p>\n

De kryptografiske verifikationsv\u00e6rkt\u00f8jer, der leveres af platformen, vil beskytte hardwarekomponenter mod indf\u00f8relse af skadelig \u00e6ndringer i firmware og sikre opstart og opbevaring af konfigurationen for at forhindre kompromittering af hovedsystemet som f\u00f8lge af angreb p\u00e5 hardwarekomponenterne eller inds\u00e6ttelse af skadelige \u00e6ndringer i forsyningsk\u00e6derne for chips. I Caliptra er der ogs\u00e5 mulighed for at verificere gyldigheden af firmwareopdateringer og relaterede platformdata (RTU, Root of Trust for Update), identificere skader p\u00e5 firmware og kritiske data (RTD, Root of Trust for Detection), samt genskabe skadede firmware og data (RTRec, Root of Trust for Recovery). <\/p>\n

Udviklingen af Caliptra foreg\u00e5r under rammerne af det f\u00e6lles Open Compute-projekt, der sigter mod at udvikle \u00e5bne specifikationer for udstyr til datacentre. Specifikationerne relateret til Caliptra distribueres under Open Web Foundation Agreement (OWFa), som er udviklet til at underst\u00f8tte distributionen af \u00e5bne standarder (lignende en FOSS-licens for specifikationer). Anvendelsen af OWFa giver mulighed for at skabe egne produkter og afledte implementeringer baseret p\u00e5 specifikationen uden betaling af royalties og tillader enhver organisation at deltage i udviklingen af specifikationen. <\/p>\n

Den grundl\u00e6ggende implementering af IP-blokken er bygget p\u00e5 den \u00e5bne RISC-V processor SWeRV EL2 og er udstyret med 384 KB RAM (128 KB DCCM, 128 KB ICCM0 og 128 KB SRAM) samt 32 KB ROM. Blandt de underst\u00f8ttede kryptografiske algoritmer n\u00e6vnes SHA256, SHA384, SHA512, ECC Secp384r1, HMAC-DRBG, HMAC SHA384, AES256-ECB, AES256-CBC og AES256-GCM.
