Google, AMD, NVIDIA thiab Microsoft, uas yog ib feem ntawm Caliptra project, tau tsim ib qho qhib nti tsim thaiv (IP thaiv) rau embedding cov cuab yeej los tsim cov cuab yeej kho vajtse uas muaj kev ntseeg siab (RoT, Hauv paus ntawm Kev Ntseeg) rau hauv cov chips. Caliptra yog ib chav tsev kho vajtse cais nrog nws tus kheej lub cim xeeb, processor thiab kev siv ntawm cryptographic primitives, uas muab kev pov thawj ntawm cov txheej txheem khau raj, cov firmware siv thiab cov cuab yeej teeb tsa khaws cia hauv lub cim xeeb tsis hloov pauv.
Caliptra tuaj yeem siv los sib koom ua ke ib qho kev ywj pheej kho vajtse rau hauv ntau lub chips, uas kuaj xyuas kev ncaj ncees thiab lav kev siv firmware txheeb xyuas thiab tso cai los ntawm cov chaw tsim khoom hauv lub cuab yeej. Caliptra tuaj yeem ua kom yooj yim thiab sib koom ua ke ntawm kev sib koom ua ke ntawm cov khoom siv kho vajtse cryptographic txheeb xyuas cov txheej txheem rau hauv CPUs, GPUs, SoCs, ASICs, network adapters, SSD drives thiab lwm yam khoom siv.
Cov cuab yeej cryptographic kev ncaj ncees thiab kev lees paub tseeb uas muab los ntawm lub platform yuav tiv thaiv cov khoom siv kho vajtse los ntawm kev qhia txog kev hloov pauv tsis zoo rau lub firmware thiab ruaj ntseg cov txheej txheem ntawm kev thauj khoom thiab khaws cov kev teeb tsa los tiv thaiv lub ntsiab system los ntawm kev cuam tshuam los ntawm kev tawm tsam ntawm cov khoom siv kho vajtse lossis kev hloov ntawm kev hloov siab phem nyob rau hauv cov khoom siv chips. Caliptra tseem muab lub peev xwm los txheeb xyuas qhov tseeb ntawm firmware hloov tshiab thiab cov ntaub ntawv ntsig txog lub platform (RTU, Hauv paus ntawm Kev Ntseeg rau Kev Hloov Kho), kuaj xyuas cov firmware puas thiab cov ntaub ntawv tseem ceeb (RTD, Lub hauv paus ntawm Kev Ntseeg rau Kev Tshawb Fawb), rov qab kho cov firmware puas thiab cov ntaub ntawv (RTRec , Lub hauv paus ntseeg rau kev rov qab).
Caliptra tab tom tsim nyob rau ntawm qhov chaw ntawm Open Compute kev sib koom ua haujlwm, tsom rau kev tsim kho cov khoom siv qhib rau cov chaw khaws ntaub ntawv. Cov kev qhia tshwj xeeb ntsig txog Caliptra raug faib los ntawm Kev Pom Zoo Qhib Web Foundation (OWFa), tsim los rau kev faib cov qauv qhib (zoo ib yam li daim ntawv tso cai qhib rau cov lus qhia tshwj xeeb). Kev siv OWFa ua rau nws muaj peev xwm tsim lawv tus kheej cov khoom lag luam thiab kev siv derivative raws li qhov tshwj xeeb yam tsis tau them cov nuj nqis thiab tso cai rau txhua lub koom haum koom nrog hauv kev txhim kho cov lus qhia tshwj xeeb.
Kev siv yooj yim ntawm IP thaiv yog tsim los ntawm qhib RISC-V processor SWeRV EL2 thiab yog nruab nrog 384KB ntawm RAM (128KB DCCM, 128KB ICCM0 thiab 128KB SRAM) thiab 32KB ROM. Txhawb cryptographic algorithms suav nrog SHA256, SHA384, SHA512 ECC Secp384r1, HMAC-DRBG, HMAC SHA384, AES256-ECB, AES256-CBC thiab AES256-GCM.
