Google teatas, et Chromebook'i seadmetes hakatakse kasutama avatud platvormi OpenTitan alusel valmistatud kiipe. Chromebook'id on esimesed kaubanduslikult saadaval olevad seadmed, milles on olemas OpenTitan. Sel aastal plaanib Google alustada andmekeskustes serveris\u00fcsteemide juurutamist OpenTitan'iga. Kiipide masstootmine on korraldatud ettev\u00f5tte Nuvoton poolt. Lisainfo kohaselt on alanud t\u00f6\u00f6tamine teise versiooni kiibi kallal, mis v\u00f5imaldab turvalise k\u00e4ivitamise ja t\u00f5estamise jaoks kasutada postkvantkryptograafia algoritme ML-DSA ja ML-KEM, mis rakendavad kr\u00fcptograafiametodeid, mis p\u00f5hinevad ristl\u00f5ikeskeemide teooria probleemide lahendamisel.

\"Chromebookidesse<\/center> <\/p>\n

OpenTitan projekt pakub usaldusv\u00e4\u00e4rsete riistvarakomponentide (RoT, Root of Trust) loomise platvormi, mida rakendatakse seal, kus on vajalik s\u00fcsteemi riist- ja tarkvaraelementide terviklikkuse tagamine. OpenTitan asutati Google'i poolt 2018. aastal, kuid 2019. aastal anti see \u00fcle mittetulundus\u00fchingule lowRISC, millele j\u00e4rgnesid sellised ettev\u00f5tted nagu Western Digital, Seagate, Nuvoton Technology, Winbond, Rivos, zeroRISC ja G+D Mobile Security. Projekti kood ja riistvarakomponentide spetsifikatsioonid on avaldatud Apache 2.0 litsentsi alusel. OpenTitan'is rakendatavad lahendused p\u00f5hinevad tehnoloogiatel, mida juba kasutatakse Google'i Titan'i kr\u00fcptograafilistes USB-tokenites ja TPM-kiipides, et tagada kinnitatud k\u00e4ivitamine. serverites<\/a> Google\u2019i infrastruktuuri ning Chromebooki ja Pixel seadmetesse. <\/p>\n

Erinevalt olemasolevatest Root of Trust'i rakendustest areneb OpenTitan kontseptsiooni j\u00e4rgi \"turvalisus l\u00e4bi l\u00e4bipaistvuse\", mis h\u00f5lmab koodi ja skeemide k\u00e4ttesaadavust ning t\u00e4iesti avatud arendusprotsessi, mis ei ole seotud konkreetsete tarnijate ja kiibitootjatega. OpenTitan on esimene turule toodud avatud rakendus Root of Trust'ist, mis toetab post-kvantmehanismi turvaliseks k\u00e4ivitamiseks, kasutades SLH-DSA (Sphincs+) digitaalsete allkirjade genereerimise algoritmi, mis on kvantarvutite purunemiskindel. <\/p>\n

OpenTitan'i alusel valmistatud kiipe saab kasutada serveri emaplaatidel, v\u00f5rgukaartidel, tarbeelektroonikas, ruuterites ja asjade interneti seadmetes, et t\u00f5estada p\u00fcsiprogramme ja laaditavaid komponente (t\u00e4htsate s\u00fcsteemiosade muutmise kaitseks), genereerida kr\u00fcptograafiliselt unikaalseid s\u00fcsteemide identifikaatoreid (riistvara asendamise kaitseks), pakkuda turvalisuse teenuseid, kaitsta kr\u00fcptograafilisi v\u00f5tmeid (v\u00f5tmete isoleerimine juhul, kui r\u00fcndaja saab f\u00fc\u00fcsilise juurdep\u00e4\u00e4su seadmetele) ja pidada isoleeritud auditilogisid, mida ei ole v\u00f5imalik redigeerida ega kustutada. <\/p>\n

OpenTitan sisaldab RoT-kiipides n\u00f5utavaid loogikablokke, nagu avatud mikroprotsessor RISC-V (RV32IMCB Ibex) arhitektuuril, kr\u00fcptograafilised kooprotsessorid, riistvaraline juhuslike numbrite generaator, v\u00f5tmehaldur DICE toega, mehhanism kaitstud andmete salvestamiseks p\u00fcsivasse ja operatiivm\u00e4lu, kaitsetehnoloogiad, sisend-\/v\u00e4ljundbloke ja turvalise k\u00e4ivitamise komponendid. Seade pakub ka plokke standardsete \u0161ifreerimisalgoritmide, nagu AES ja HMAC-SHA256, rakendustega ning matemaatiliste tehete kiirendajat, mis on vajalik avatud v\u00f5tmete digitaalsete allkirjadega t\u00f6\u00f6tamiseks. <\/p>\n
