Mittekommertslik organisatsioon lowRISC, mis juhib RISC-V arhitektuuril p\u00f5hineva avatud mikroprotsessori arendust, teatas, et esimene kaubanduseks valmis kiip, mis p\u00f5hineb avatud platvormil OpenTitan, on n\u00fc\u00fcd saadaval ja valmis tootmiseks. Alguses loodi projekt Google'i poolt, kuid p\u00e4rast \u00fclekannet organisatsioonile lowRISC liitusid selle arendusega sellised ettev\u00f5tted nagu Western Digital, Seagate, Nuvoton Technology, Winbond, Rivos, zeroRISC ja G+D Mobile Security. Projekti seotud kood ja riistvara spetsifikatsioonid on avaldatud Apache 2.0 litsentsi alusel. <\/p>\n

Erinevalt olemasolevatest Root of Trust'i rakendustest areneb OpenTitan vastavalt kontseptsioonile \"turvalisus l\u00e4bi l\u00e4bipaistvuse\", mis t\u00e4hendab koodi ja skeemide k\u00e4ttesaadavust ning t\u00e4iesti avatud arendusprotsessi, mis ei ole seotud konkreetsete tarnijate ja kiibitootjatega. OpenTitani lahenduste aluseks on tehnoloogiad, mida juba kasutatakse Google Titan kr\u00fcptograafilistes USB-tokenites ja TPM-kiipides, et tagada kontrollitud k\u00e4ivitamine, mida installitakse serverites<\/a> Google'i infrastruktuuris ning ka Chromebooki ja Pixel seadmetes. <\/p>\n

OpenTitan on platvorm usaldusv\u00e4\u00e4rsete riistvarakomponentide (RoT, Root of Trust) loomiseks, mida saab rakendada seal, kus on vajalik tagada s\u00fcsteemi riist- ja tarkvara elementide terviklik seisund, kinnitades, et s\u00fcsteemi kriitilised osad ei ole olnud muudetud ja p\u00f5hinevad tootja poolt kinnitatud ja sertifitseeritud koodil. Projekt pakub valmisolekut, testitud ja usaldusv\u00e4\u00e4rset raamistiku, mis aitab suurendada usaldusv\u00e4\u00e4rsust loodud lahendustes ning v\u00e4hendada kulusid spetsialiseeritud turvalisuse kiippide arendamisel. <\/p>\n

OpenTitani p\u00f5hinevaid kiipe saab kasutada serverite emaplaatides, v\u00f5rgukaartides, tarbijaseadmetes, ruuterites ja asjade Interneti seadmetes, et kinnitada kindlaksm\u00e4\u00e4ratud p\u00fcsivara ja laaditavaid komponente, samuti genereerida kr\u00fcptograafiliselt unikaalseid s\u00fcsteemi identifikaatoreid (seadmestikuv\u00f5ltsimise kaitse), kaitsta kr\u00fcptov\u00f5tmeid (v\u00f5tmete isoleerimine f\u00fc\u00fcsilise juurdep\u00e4\u00e4su korral seadmetele) ning pakkuda turvalisuse teenuseid ja pidada eraldatud auditilogisid, mida ei saa redigeerida v\u00f5i kustutada. <\/p>\n

OpenTitan sisaldab erinevaid loogikablokke, mis on n\u00f5utud RoT-kiipides, nagu avatud RISC-V arhitektuuril p\u00f5hinev mikroprocessor (RV32IMCB Ibex), kr\u00fcptograafilised kooprotsessorid, riistvaraline juhuslike arvude generaator, v\u00f5tmehaldur DICE toe ja andmete turvalise salvestamise mehhanismiga p\u00fcsivaramus ja p\u00f5him\u00e4lu, kaitsetehnoloogiad, sisend-\/v\u00e4ljundplokid, turvalise k\u00e4ivitamise vahendid jne. Seade pakub ka plokke standardsete kr\u00fcpteerimisalgoritmide, nagu AES ja HMAC-SHA256, rakendamiseks ning matemaatiliste operatsioonide kiirendit, mida rakendatakse digiallkirjade t\u00f6\u00f6tlemiseks avatud v\u00f5tmep\u00f5histe algoritmide, nagu RSA ja elliptiliste k\u00f5verate alusel, puhul.
