Google esituse<\/a><\/noindex> uus avatud projekt OpenTitan<\/a><\/noindex>, mis esindab platvormi usaldusv\u00e4\u00e4rsete riistvarakomponentide (RoT, Root of Trust) loomiseks. OpenTitani aluseks on tehnoloogiad, mida juba kasutatakse kr\u00fcptograafilistes USB-tokenites Google Titan<\/a><\/noindex> ja TPM-kiipides<\/a><\/noindex> verifitseeritud k\u00e4ivitamise tagamiseks, mida installitakse Google'i infrastruktuuri serveritesse, samuti Chromebookide ja Pixel-seadmete peale. Seotud projektikood ja riistvarakomponentide spetsifikatsioonid avaldatud<\/a><\/noindex> GitHubis Apache 2.0 litsentsi all.<\/p>\n

Erinevalt olemasolevatest Root of Trust'i rakendustest areneb uus projekt vastavalt kontseptsioonile \u201eturvalisus l\u00e4bi l\u00e4bipaistvuse\u201c, mis t\u00e4hendab t\u00e4ielikult avatud arendusprotsessi ja juurdep\u00e4\u00e4su koodile ja skeemidele. OpenTitanit saab kasutada valmis, t\u00f5estatud ja usaldusv\u00e4\u00e4rse raamistikuna, mis aitab suurendada usaldusv\u00e4\u00e4rsust loodud lahenduste suhtes ning v\u00e4hendada kulusid spetsialiseeritud turvakiipide arendamisel. OpenTitan areneb s\u00f5ltumatul platvormil koost\u00f6\u00f6projektina, mis ei ole seotud konkreetsete tarnijate ja kiibitootjatega. <\/p>\n

OpenTitani arendust juhib mittetulundus\u00fching lowRISC<\/a><\/noindex>, mis arendab avatud mikroprotsessorit RISC-V arhitektuuril. Koost\u00f6\u00f6d OpenTitani nimel on juba alustanud ettev\u00f5tted G+D Mobile Security, Nuvoton Technology ja Western Digital, samuti Z\u00fcrichi Tehnika\u00fclikool ja Cambridge'i \u00dclikool, mille teadlased arendavad turvalist protsessori arhitektuuri CHERI<\/a><\/noindex> (Capability Hardware Enhanced RISC Instructions) ja hiljuti on saadud<\/a><\/noindex> 190 miljoni euro suuruse toetuse, et kohandada sellega seotud tehnoloogiaid ARM-protsessorite jaoks ja luua uue riistvaraplatvormi protot\u00fc\u00fcp nimega Morello.<\/p>\n

OpenTitani projekt h\u00f5lmab erinevate loogiliste komponentide arendamist, mida n\u00f5utakse RoT-kiipides, sealhulgas avatud mikroprotsessorit lowRISC Ibex<\/a><\/noindex> RISC-V arhitektuuril, kr\u00fcptograafilisi kooprotsessoreid, riistvaralist juhuslike numberite genereerijat, v\u00f5tme- ja andmehierarhiaid p\u00fcsivus- ja operatiivm\u00e4lus, kaitsemehhanisme, sisendi\/v\u00e4ljundi blokke, turvalise k\u00e4ivitamise vahendeid jne. OpenTitanit saab rakendada seal, kus on vajalik tagada s\u00fcsteemi riistvara ja tarkvara komponentide terviklik seisund, kinnitades, et kriitilised s\u00fcsteemi komponendid ei ole asendatud ning p\u00f5hinevad tootja poolt kinnitatud ja volitatud koodil. <\/p>\n

OpenTitani baasil valmistatud kiipe saab kasutada
\nserveri p\u00f5hikettadel, v\u00f5rgukaartidel, tarbeseadmetes, marsruuterites, asjade interneti seadmetes, et verifitseerida p\u00fcsivara (tuvastada pahavara n\u00e4ol esinevaid p\u00fcsivara muudatusi), anda s\u00fcsteemile kr\u00fcptograafiliselt ainulaadne identifikaator (seadmise kaitsmine), kaitsta kr\u00fcptograafilisi v\u00f5tmeid (v\u00f5tmete isolatsioon f\u00fc\u00fcsilise juurdep\u00e4\u00e4su korral seadmele) ja pakkuda seotud turvateenuseid ning pidada isoleeritud auditi logi, mida ei saa redigeerida ega kustutada.<\/p>\n
