Google, AMD, NVIDIA ja Microsoft arendavad koost\u00f6\u00f6projekti Caliptra raames avatud mikroskeemide disainiblokki (IP-blokk), et integreerida usaldusv\u00e4\u00e4rsete riistvarakomponentide (RoT, Root of Trust) loomise t\u00f6\u00f6riistadesse. Caliptra on eraldi riistvarablokk oma m\u00e4lu, protsessori ja kr\u00fcptograafiliste primitivi rakendusega, mis tagab laadimisprotsessi, kasutatavate p\u00fcsivara ja energia s\u00f5ltumatus m\u00e4lus salvestatud seadme konfigureerimise kontrollimise. <\/p>\n

Caliptra saab kasutada erinevate s\u00f5ltumatute riistvarablokkide kiipidesse integreerimiseks, mis teostavad integriteedi kontrollimist ja tagavad seadmes tootja poolt kontrollitud ja volitatud p\u00fcsivara kasutamise. Caliptra v\u00f5ib oluliselt lihtsustada ja \u00fchtlustada kr\u00fcptograafilise autentimise mehhanismide integreerimist CPUdesse, GPUdesse, SoCidesse, ASICdesse, v\u00f5rgukaartidesse, SSD-diskidesse ja muusse seadmesse. <\/p>\n

Platvormi pakutavad kr\u00fcptograafilise autentimise ja t\u00f5elisuse kontrollimise t\u00f6\u00f6riistad aitavad kaitsta riistvarakomponente pahatahtlike muudatuste sissetungi eest p\u00fcsivara ning tagada laadimisprotsessi ja konfiguratsiooni salvestamise turvalisuse, et v\u00e4ltida s\u00fcsteemi p\u00f5hielementide kompromiteerimist r\u00fcnnakute t\u00f5ttu riistvarakomponentidele v\u00f5i pahatahtlike muudatuste sisestamist kiipide tarnimise ahelatesse. Caliptras on ka v\u00f5imalus p\u00fcsivara ja seotud platvormi andmete (RTU, Root of Trust for Update) autentsuse kontrollimiseks, p\u00fcsivara ja kriitiliste andmete kahjustuste (RTD, Root of Trust for Detection) tuvastamiseks, kahjustatud p\u00fcsivara ja andmete taastamiseks (RTRec, Root of Trust for Recovery). <\/p>\n

Caliptra v\u00e4ljat\u00f6\u00f6tamine toimub avatud arvutite projekti koost\u00f6\u00f6pindadel, mille eesm\u00e4rk on avatud riistvarastandardite arendamine andmekeskuste varustamiseks. Caliptraga seotud spetsifikatsioonid levitatakse Open Web Foundation Agreement (OWFa) alusel, mis on loodud avatud standardite levitamiseks (sarnaneb avatud allikate litsentsiga spetsifikatsioonide jaoks). OWFa kasutamine v\u00f5imaldab luua spetsifikatsioonide alusel oma tooteid ja derivatiivteoste, ilma et tuleks maksta litsentsitasusid, ning annab igasugustele organisatsioonidele v\u00f5imaluse osaleda spetsifikatsioonide arendamisel. <\/p>\n

Baasiline IP-bloki rakendamine p\u00f5hineb avatud RISC-V protsessoril SWeRV EL2 ja on varustatud 384 KB RAM-iga (128 KB DCCM, 128 KB ICCM0 ja 128 KB SRAM) ning 32 KB ROM-iga. Toetatud kr\u00fcptoalgoritmide hulka kuuluvad SHA256, SHA384, SHA512, ECC Secp384r1, HMAC-DRBG, HMAC SHA384, AES256-ECB, AES256-CBC ja AES256-GCM.
