Tvrtke Google, AMD, NVIDIA i Microsoft razvile su, u sklopu zajedni\u010dkog projekta Caliptra, otvoreni blok dizajna \u010dipova (IP-blok) za integraciju u \u010dipove sredstava za stvaranje pouzdanih hardverskih komponenti (RoT, Root of Trust). Caliptra predstavlja zasebni hardverski blok sa svojom memorijom, procesorom i implementacijom kriptografskih primitava, osiguravaju\u0107i verifikaciju procesa pokretanja, kori\u0161tenih firmware-a i konfiguracije ure\u0111aja pohranjene u nepromjenjivoj memoriji. <\/p>\n

Caliptra se mo\u017ee primijeniti za integraciju u razli\u010dite \u010dipove neovisnog hardverskog bloka koji provodi provjeru cjelovitosti i osigurava kori\u0161tenje u ure\u0111aju provjerenih i ovla\u0161tenih firmware-a od strane proizvo\u0111a\u010da. Caliptra mo\u017ee zna\u010dajno pojednostaviti i unificirati integraciju ugra\u0111enih hardverskih mehanizama kriptografske verifikacije u CPU, GPU, SoC, ASIC, mre\u017ene adaptere, SSD-ove i drugo opreme. <\/p>\n

Alati za kriptografsku verifikaciju cjelovitosti i autenti\u010dnosti koje pru\u017ea platforma omogu\u0107it \u0107e za\u0161titu hardverskih komponenti od zlonamjernih promjena u firmware-u i osigurati proces pokretanja i pohranu konfiguracije, kako bi se sprije\u010dila kompromitacija osnovnog sustava uslijed napada na hardverske komponente ili umetanja zlonamjernih promjena u lance opskrbe \u010dipova. U Caliptri je tako\u0111er osigurana mogu\u0107nost provjere autenti\u010dnosti a\u017euriranja firmware-a i povezanih podataka s platformom (RTU, Root of Trust for Update), otkrivanja o\u0161te\u0107enja firmware-a i kriti\u010dnih podataka (RTD, Root of Trust for Detection), a tako\u0111er i obnavljanja o\u0161te\u0107enih firmware-a i podataka (RTRec, Root of Trust for Recovery). <\/p>\n

Razvoj Caliptre odvija se na platformi zajedni\u010dkog projekta Open Compute, koji je usmjeren na razvoj otvorenih specifikacija opreme za opremanje data centara. Specifikacije povezane s Caliptra distribuiraju se kori\u0161tenjem Open Web Foundation Agreement (OWFa), koji je razvijen za distribuciju otvorenih standarda (sli\u010dno licencama otvorenog koda za specifikacije). Primjena OWFa omogu\u0107ava kreiranje proizvoda i izvedenica temeljenih na specifikaciji bez pla\u0107anja tantijema i omogu\u0107ava svim organizacijama sudjelovanje u razvoju specifikacije. <\/p>\n

Osnovna implementacija IP-bloka temelji se na otvorenom RISC-V procesoru SWeRV EL2 i opremljena je s 384KB RAM-a (128KB DCCM, 128KB ICCM0 i 128KB SRAM) i 32KB ROM-a. Me\u0111u podr\u017eanim kriptalgoritmima navedeni su SHA256, SHA384, SHA512, ECC Secp384r1, HMAC-DRBG, HMAC SHA384, AES256-ECB, AES256-CBC i AES256-GCM.
