Google, AMD, NVIDIA ja Microsoft on v\u00e4lja t\u00f6\u00f6tanud avatud mikroskeemide projekteerimisse (IP-bloki) s\u00fcsteemi, et integreerida usaldusv\u00e4\u00e4rsete riistvarakomponentide (RoT, Root of Trust) loomise tehnoloogiaid. Caliptra on iseseisev riistvarablokk, millel on oma m\u00e4lu, protsessor ja kr\u00fcptograafiliste primitivate rakendused, tagades k\u00e4ivitamisprotsessi, kasutatavate p\u00fcsivormide ja energiavarustuses m\u00e4lu konfigureerimise kontrollimise. <\/p>\n

Caliptra saab rakendada erinevates mitte s\u00f5ltuvates riistvarablokkides, mis teostavad terviklikkuse kontrolli ja garanteerivad seadmes tootja poolt kontrollitud ja volitatud p\u00fcsivormide kasutamise. Caliptra v\u00f5ib m\u00e4rkimisv\u00e4\u00e4rselt lihtsustada ja \u00fchtlustada kr\u00fcptograafilise autentimise integreerimist CPU-desse, GPU-desse, SoC-desse, ASIC-desse, v\u00f5rgukaartidesse, SSD-kettadesse ja muusse varustusse. <\/p>\n

Platvormi pakutavad kr\u00fcptograafilise kontrollimise vahendid tagavad riistvarakomponentide kaitse pahatahtlike muudatuste eest, kaitstes s\u00fcsteemi \u00fcleslaadimist ja konfiguratsiooni salvestamist ning v\u00e4ltides p\u00f5hiraami kompromiteerimist r\u00fcnnakute v\u00f5i pahatahtlike muudatuste t\u00f5ttu kiibide tarnimisahelates. Caliptras on samuti ette n\u00e4htud v\u00f5imalus kontrollida p\u00fcsivara ja platvormiga seotud andmete (RTU, Root of Trust for Update) autentsust, tuvastada p\u00fcsivara ja kriitiliste andmete (RTD, Root of Trust for Detection) kahjustusi ning taastada kahjustatud p\u00fcsivara ja andmeid (RTRec, Root of Trust for Recovery). <\/p>\n

Caliptra arendus toimub Open Compute koost\u00f6\u00f6projekti raames, mille eesm\u00e4rk on arendada avatud riistvarastandardite spetsifikatsioone andmekeskuste varustamiseks. Caliptra spetsifikatsioonid levitatakse Open Web Foundation Agreement (OWFa) lepingu alusel, mis on v\u00e4lja t\u00f6\u00f6tatud avatud standardite levitamiseks (sarnane avatud tarkvara litsentsile spetsifikatsioonide jaoks). OWFa rakendamine v\u00f5imaldab luua oma tooteid ja tuletatud teostusi spetsifikatsiooni alusel ilma autoritasude maksmata ja v\u00f5imaldab igasugustel organisatsioonidel osaleda spetsifikatsiooni arendamises. <\/p>\n

IP-ploki p\u00f5hiimplementatsioon p\u00f5hineb avatud RISC-V protsessoril SWeRV EL2 ja sellel on 384 KB RAM (128 KB DCCM, 128 KB ICCM0 ja 128 KB SRAM) ning 32 KB ROM. Toetatud kr\u00fcptoalgoritmid h\u00f5lmavad SHA256, SHA384, SHA512, ECC Secp384r1, HMAC-DRBG, HMAC SHA384, AES256-ECB, AES256-CBC ja AES256-GCM.
