F\u00f6retagen Google, AMD, NVIDIA och Microsoft har tillsammans utvecklat en \u00f6ppen designblock f\u00f6r kretsar (IP-block) inom ramen f\u00f6r projektet Caliptra, avsett f\u00f6r integrering i chip som skapar p\u00e5litliga h\u00e5rdvarukomponenter (RoT, Root of Trust). Caliptra \u00e4r en separat h\u00e5rdvarublock med egen minnes- och processenhet samt implementering av kryptografiska primitiva, som s\u00e4kerst\u00e4ller verifiering av startprocessen, de anv\u00e4nda fastvaror och konfigurationen som lagras i icke-flyktigt minne. <\/p>\n

Caliptra kan anv\u00e4ndas f\u00f6r att integrera i olika chip av oberoende h\u00e5rdvarublock som verifierar integritet och garanterar anv\u00e4ndningen av verifierade och av tillverkaren auktoriserade fastvaror i enheten. Caliptra kan avsev\u00e4rt f\u00f6renkla och standardisera integreringen av inbyggda h\u00e5rdvarumekanismer f\u00f6r kryptografisk verifiering i CPU, GPU, SoC, ASIC, n\u00e4tverksadapter, SSD-enheter och annan utrustning. <\/p>\n

De kryptografiska verifieringsverktyg som tillhandah\u00e5lls av plattformen kommer att skydda h\u00e5rdvarukomponenter fr\u00e5n infogande av skadliga f\u00f6r\u00e4ndringar i fastvaror och s\u00e4kra startprocessen och lagringen av konfigurationen f\u00f6r att f\u00f6rhindra kompromettering av det prim\u00e4ra systemet som en f\u00f6ljd av attacker mot h\u00e5rdvarukomponenterna eller inmatning av skadliga f\u00f6r\u00e4ndringar i chipets leveranskedjor. I Caliptra finns ocks\u00e5 m\u00f6jligheten att verifiera \u00e4ktheten av fastvaruuppdateringar och relaterade plattformsdata (RTU, Root of Trust for Update), uppt\u00e4ckten av skadade fastvaror och kritiska data (RTD, Root of Trust for Detection), samt \u00e5terst\u00e4llning av skadade fastvaror och data (RTRec, Root of Trust for Recovery). <\/p>\n

Utvecklingen av Caliptra genomf\u00f6rs inom ramen f\u00f6r det gemensamma projektet Open Compute, som syftar till att fr\u00e4mja \u00f6ppna specifikationer f\u00f6r utrustning av datacenter. Specifikationerna kopplade till Caliptra sprids under Open Web Foundation Agreement (OWFa), som har utvecklats f\u00f6r att sprida \u00f6ppna standarder (liknande en \u00f6ppen programvarulicens f\u00f6r specifikationer). Genom att anv\u00e4nda OWFa m\u00f6jligg\u00f6rs skapande av egna produkter och avledningar baserade p\u00e5 specifikationen utan royaltyavgifter och till\u00e5ter alla organisationer att delta i utvecklingen av specifikationen. <\/p>\n

Den grundl\u00e4ggande implementationen av IP-blocket \u00e4r baserad p\u00e5 den \u00f6ppna RISC-V-processorn SWeRV EL2 och \u00e4r utrustad med 384KB RAM (128KB DCCM, 128KB ICCM0 och 128KB SRAM) och 32KB ROM. Bland de st\u00f6dja kryptografiska algoritmerna finns SHA256, SHA384, SHA512, ECC Secp384r1, HMAC-DRBG, HMAC SHA384, AES256-ECB, AES256-CBC och AES256-GCM.
