Mittekasumlik organisatsioon lowRISC, mis kureerib avatud RISC-V arhitektuuri p\u00f5hjal arendatava vabak\u00e4itleva mikroprotsessori v\u00e4ljat\u00f6\u00f6tamist, kuulutas v\u00e4lja esimese kaubanduslikuks tootmiseks valmis kiibi, mis on rajatud avatud platvormile OpenTitan, mille arendamine toimub kui s\u00f5ltumatu koost\u00f6\u00f6projekt. Alguses asutas projekti Google, kuid hiljem liikus arengusse organisatsioon lowRISC, kuhu lisandusid sellised ettev\u00f5tted nagu Western Digital, Seagate, Nuvoton Technology, Winbond, Rivos, zeroRISC ja G+D Mobile Security. Projekti seotud kood ja riistvara komponentide spetsifikatsioonid on avaldatud Apache 2.0 litsentsi alusel. <\/p>\n

Erinevalt olemasolevatest usaldusrootori (Root of Trust) rakendustest areneb OpenTitan vastavalt kontseptsioonile \"turvalisus l\u00e4bi l\u00e4bipaistvuse\", mille alla kuuluvad koodi ja skeemide k\u00e4ttesaadavus ning t\u00e4ielikult avatud arendusprotsess, mis ei ole seotud konkreetsete tarnijate ja chipitootjatega. OpenTitani rakendusp\u00f5hised lahendused tuginevad tehnoloogiatele, mida juba kasutatakse Google Titan kr\u00fcptograafilistes USB-tokenites ja TPM-kiipides, et tagada kinnitatud boot, mis paigaldatakse serverites<\/a> Google\u2019i infrastruktuuri ning Chromebooki ja Pixel seadmetesse. <\/p>\n

OpenTitan on platvorm usaldusv\u00e4\u00e4rsete riistvara komponentide (RoT, Root of Trust) loomiseks, mida saab kasutada seal, kus on vajalik tagada s\u00fcsteemi riist- ja tarkvarakomponentide puutumatuse olek, t\u00f5endades, et s\u00fcsteemi kriitilised osad ei ole vahetatud ja tuginevad tootja poolt kontrollitud ja autoriseeritud koodile. Projekt pakub valmis, testitud ja usaldusv\u00e4\u00e4rset raamistikku, mis aitab suurendada usaldusv\u00e4\u00e4rsust toodetud lahendustes ning v\u00e4hendada kulusid spetsialiseeritud turvalisuse kiipide arendamisel. <\/p>\n

OpenTitani p\u00f5hinevaid kiipe saab kasutada serveri emaplaatides, v\u00f5rkaartides, tarbelistes seadmetes, marsruuterites ja asjade interneti seadmetes, et valideerida p\u00fcsivara ja laaditavaid komponente, samuti genereerida s\u00fcsteemi kr\u00fcptograafiliselt unikaalseid identifikaatoreid (seadmestiku petmise kaitse), kaitsta kr\u00fcptograafilisi v\u00f5tmeid (v\u00f5tmete isolatsioon juhuks, kui r\u00fcndaja p\u00e4\u00e4seb seadmele f\u00fc\u00fcsiliselt ligi), pakkuda turvalisuse teenuseid ja pidada eraldiseisvat auditi logi, mida ei saa redigeerida v\u00f5i kustutada. <\/p>\n

OpenTitan h\u00f5lmab erinevaid loogilisi plokke, mis on n\u00f5udlikud RoT-kiipides, nagu avatud mikroprotsessor RISC-V arhitektuuril (RV32IMCB Ibex), kr\u00fcptograafilised kaasprotsessorid, riistvaraline juhuslike arvude generaator, v\u00f5tmehaldur DICE toe ja kaitstud andmesalvestuse mehhanismidega p\u00fcsivalt ja t\u00f6\u00f6m\u00e4lus, kaitsetehnoloogiad, sisend-\/v\u00e4ljav\u00f5tu plokid, turvalise k\u00e4ivitamise vahendid jne. Seade pakub ka plokke, mis rakendavad t\u00fc\u00fcpilisi kr\u00fcpteerimisalgoritme, nagu AES ja HMAC-SHA256, ning matemaatikaoperatsioonide kiirendit, mida kasutatakse digitaalse allkirja algoritmides, mis p\u00f5hinevad avalikel v\u00f5titest, n\u00e4iteks RSA ja elliptiliste k\u00f5verate algoritmid.
