Nekomercijalna organizacija lowRISC, koja koordinira razvoj slobodnog mikroprocesora temeljenog na RISC-V arhitekturi, najavila je dostupnost prvog \u010dipa spremnog za komercijalnu proizvodnju, temeljenog na otvorenoj platformi OpenTitan, koja se razvija kao neovisni zajedni\u010dki projekt. Projekt je izvorno osnovao Google, no nakon prijenosa organizaciji lowRISC, pridru\u017eile su mu se tvrtke poput Western Digitala, Seagatea, Nuvoton Technology, Winbonda, Rivosa, zeroRISC-a i G+D Mobile Security. S povezanim projektom, kod i specifikacije hardverskih komponenti objavljeni su pod Apache 2.0 licencom. <\/p>\n

Za razliku od postoje\u0107ih implementacija Root of Trust, OpenTitan se razvija u skladu s konceptom \u201esigurnost kroz transparentnost\u201c, koji podrazumijeva dostupnost koda i shema, kao i potpuno otvoren proces razvoja, koji nije vezan za specifi\u010dne dobavlja\u010de i proizvo\u0111a\u010de \u010dipova. U sr\u017ei rje\u0161enja koja se primjenjuju u OpenTitan le\u017ee tehnologije ve\u0107 kori\u0161tene u kriptografskim USB tokenima Google Titan i TPM \u010dipovima za osiguranje verifikovane boot sekvence. poslu\u017eiteljima<\/a> infrastrukturi Googlea, kao i na ure\u0111ajima Chromebook i Pixel. <\/p>\n

OpenTitan predstavlja platformu za izradu povjerljivih hardverskih komponenti (RoT, Root of Trust), koja se mo\u017ee primijeniti tamo gdje je potrebno jam\u010diti cjelovitost hardverskih i softverskih elemenata sustava, osiguravaju\u0107i da kriti\u010dne dijelove sustava nisu izmijenjene i temelje se na provjerenom i od strane proizvo\u0111a\u010da autoriziranom kodu. Projekt pru\u017ea gotovu, testiranu i pouzdanu strukturu koja omogu\u0107uje pove\u0107anje povjerenja u razvijena rje\u0161enja i smanjenje tro\u0161kova pri razvoju specijaliziranih \u010dipova za osiguranje sigurnosti. <\/p>\n

OpenTitan \u010dipovi mogu se koristiti u mati\u010dnim plo\u010dama servera, mre\u017enim karticama, potro\u0161a\u010dkim ure\u0111ajima, usmjeriva\u010dima i ure\u0111ajima interneta stvari za verifikaciju firmware-a i u\u010ditavanih komponenti, kao i za generiranje kriptografski jedinstvenih identifikatora sustava (za\u0161tita od zamjene hardvera), za\u0161titu kriptografskih klju\u010deva (izolacija klju\u010deva u slu\u010daju fizi\u010dkog pristupa napada\u010da na opremu), pru\u017eanje povezanih sigurnosnih usluga te vo\u0111enje izoliranog audit loga koji se ne mo\u017ee ure\u0111ivati ili brisati. <\/p>\n

OpenTitan uklju\u010duje razli\u010dite logi\u010dke blokove, tra\u017eene u RoT \u010dipovima, kao \u0161to su otvoreni mikroprocesor temeljen na RISC-V arhitekturi (RV32IMCB Ibex), kriptografski koprocesori, hardverski generator slu\u010dajnih brojeva, menad\u017eer klju\u010deva s podr\u0161kom za DICE, mehanizam za za\u0161titu podataka pohranjenih u trajnoj i radnoj memoriji, tehnologije za\u0161tite, ulazno\/izlazne ure\u0111aje, sredstva za sigurnu podizanje sustava, itd. Ure\u0111aj tako\u0111er pru\u017ea blokove s implementacijom standardnih kriptografskih algoritama, kao \u0161to su AES i HMAC-SHA256, te ubrziva\u010d matemati\u010dkih operacija koji se primjenjuju u algoritmima za rad sa digitalnim potpisima temeljenim na javnim klju\u010devima, poput RSA i algoritama temeljenih na elipti\u010dnim krivuljama.
