Google'i ettev\u00f5te esitles<\/a><\/noindex> uus avatud projekt OpenTitan<\/a><\/noindex>, mis on platvorm usaldusv\u00e4\u00e4rsete riistvara komponentide (RoT, Trust Root) loomiseks. OpenTitani aluseks on tehnoloogiad, mida on juba rakendatud kr\u00fcptograafilistes USB-tokenites Google Titan<\/a><\/noindex> ja TPM-kiipides<\/a><\/noindex> , et tagada kinnitatud k\u00e4ivitamine, mis on paigaldatud Google'i infrastruktuuri serveritesse ning Chromebooki ja Pixel seadmetesse. Projektiga seotud kood ja riistvara komponentide spetsifikatsioonid avaldatud<\/a><\/noindex> on saadaval GitHubis Apache 2.0 litsentsi all.<\/p>\n

Erinevalt olemasolevatest Realisatsioonidest Root of Trust, uus projekt areneb vastavalt kontseptsioonile \u201eturvalisus l\u00e4bi l\u00e4bipaistvuse\u201c, mis t\u00e4hendab t\u00e4ielikult avatud arendusprotsessi ning koodi ja skeemide k\u00e4ttesaadavust. OpenTitanit saab kasutada kui valmis, kontrollitud ja usaldusv\u00e4\u00e4rset raamistiku, mis suurendab usaldust loodud lahenduste vastu ning v\u00e4hendab spetsialiseeritud turvakiipide arendamise kulusid. OpenTitan areneb iseseisval platvormil kui koost\u00f6\u00f6projekt, mis ei ole seotud konkreetsete tarnijate ja kiibitootjatega. <\/p>\n

OpenTitani arendust juhib mittetulundus\u00fching lowRISC<\/a><\/noindex>, mis arendab avatud mikroprotsessorit RISC-V arhitektuuri alusel. OpenTitaniga on juba liitunud ettev\u00f5tted G+D Mobile Security, Nuvoton Technology ja Western Digital, samuti Z\u00fcrichi F\u00f6deraalne Tehnika\u00fclikool ja Cambridge'i \u00dclikool, mille teadlased arendavad turvalist protsessori arhitektuuri CHERI<\/a><\/noindex> (Capability Hardware Enhanced RISC Instructions) ja hiljuti sai<\/a><\/noindex> saadud 190 miljoni euro suurune toetus, et kohandada sellega seotud tehnoloogiaid ARM-protsessoritele ja luua uue riistvaraplatformi protot\u00fc\u00fcp Morello.<\/p>\n

OpenTitan h\u00f5lmab erinevate loogikakomponentide arendamist, mida vajatakse RoT-kiipides, sealhulgas avatud mikroprotsessor lowRISC Ibex<\/a><\/noindex> RISC-V arhitektuuril p\u00f5hinevad kr\u00fcptograafilised coprotsessorid, riistvaraline juhuslike numbrite generaator, v\u00f5tmete ja andmete hoidmise hierarhia p\u00fcsivalt ja j\u00e4rgnevalt m\u00e4lu, kaitsemehhanismid, sisendi\/v\u00e4ljundi moodulid, turvalise k\u00e4ivitamise vahendid jne. OpenTitanit saab rakendada seal, kus on vajalik tagada s\u00fcsteemi riistvarakomponentide ja tarkvara puutumatuse seisund, kinnitades, et kriitiliselt olulised s\u00fcsteemikomponendid ei ole olnud asendatud ja p\u00f5hinevad tootja poolt kinnitatud ja autoriseeritud koodil. <\/p>\n

OpenTitani p\u00f5hjal valmistatud kiipe saab kasutada
\nserveri emaplaatidel, v\u00f5rgu kaartides, tarbimise seadmetes, marsruuterites, asjade interneti seadmetes, et kontrollida tarkvarav\u00e4rskendusi (kahjurprogrammi poolt tarkvara modifitseerimise tuvastamine), pakkuda unikaalset kr\u00fcptograafilist s\u00fcsteemi identifikaatorit (seadmestiku asendamise kaitse), kaitsta kr\u00fcptograafilisi v\u00f5tmeid (v\u00f5tmete eraldamine, kui r\u00fcndajal omandatakse f\u00fc\u00fcsiline juurdep\u00e4\u00e4s seadmele), pakkuda turvalisuse teenuseid ja s\u00e4ilitada isoleeritud auditi logi, mida ei saa redigeerida v\u00f5i kustutada.<\/p>\n
