Compania Google a prezentat<\/a><\/noindex> proiect nou deschis OpenTitan<\/a><\/noindex>, care reprezint\u0103 o platform\u0103 pentru crearea de componente hardware de \u00eencredere (RoT, Root of Trust). Tehnologiile deja utilizate \u00een token-uri USB criptografice stau la baza OpenTitan. Google Titan<\/a><\/noindex> \u0219i cipuri TPM<\/a><\/noindex> pentru asigurarea unei \u00eenc\u0103rc\u0103ri verificate, instalate pe serverele din infrastructura Google, precum \u0219i pe dispozitivele Chromebook \u0219i Pixel. Codul \u0219i specifica\u021biile hardware asociate proiectului sunt publicate<\/a><\/noindex> sunt disponibile pe GitHub sub licen\u021ba Apache 2.0.<\/p>\n

Spre deosebire de implement\u0103rile existente ale Root of Trust, noul proiect se dezvolt\u0103 conform conceptului \u201esecuritate prin transparen\u021b\u0103\u201d, care presupune un proces de dezvoltare complet deschis \u0219i accesibilitate la coduri \u0219i scheme. OpenTitan poate fi utilizat ca o structur\u0103 gata, verificat\u0103 \u0219i de \u00eencredere, care permite cre\u0219terea \u00eencrederii \u00een solu\u021biile create \u0219i reducerea costurilor \u00een dezvoltarea chipseturilor specializate pentru asigurarea securit\u0103\u021bii. OpenTitan se va dezvolta pe o platform\u0103 independent\u0103 ca un proiect colaborativ, f\u0103r\u0103 a fi legat de furnizori sau produc\u0103tori specifici de cipuri. <\/p>\n

Dezvoltarea OpenTitan va fi coordonat\u0103 de o organiza\u021bie non-profit lowRISC<\/a><\/noindex>, care dezvolta un microprocesor liber bazat pe arhitectura RISC-V. La colaborarea pentru OpenTitan s-au al\u0103turat deja companiile G+D Mobile Security, Nuvoton Technology \u0219i Western Digital, precum \u0219i Politehnica din Zurich \u0219i Universitatea din Cambridge, al c\u0103rei cercet\u0103tor dezvolt\u0103 arhitectura procesorului securizat CHERI<\/a><\/noindex> (Capability Hardware Enhanced RISC Instructions) \u0219i recent au primit<\/a><\/noindex> a ob\u021binut un grant de 190 milioane de euro pentru adaptarea tehnologiilor asociate pentru microprocesoarele ARM \u0219i crearea unui prototip pentru o nou\u0103 platform\u0103 hardware Morello.<\/p>\n

Proiectul OpenTitan acoper\u0103 dezvoltarea diferitelor componente logice solicitate \u00een cipurile RoT, inclusiv un microprocesor deschis lowRISC Ibex<\/a><\/noindex> bazat pe arhitectura RISC-V, coprocessorii criptografici, generatorul hardware de numere aleatorii, ierarhia de stocare a cheilor \u0219i datelor \u00een memorie persistent\u0103 \u0219i operativ\u0103, mecanismele de protec\u021bie, blocurile de intrare\/ie\u0219ire, mijloacele de \u00eenc\u0103rcare securizat\u0103 etc. OpenTitan poate fi utilizat acolo unde este necesar\u0103 garan\u021bia integrit\u0103\u021bii sistemului hardware \u0219i software, asigur\u00e2ndu-se c\u0103 componentele esen\u021biale ale sistemului nu au fost \u00eenlocuite \u0219i se bazeaz\u0103 pe un cod aprobat \u0219i autorizat de produc\u0103tor. <\/p>\n

Chipurile bazate pe OpenTitan pot fi utilizate \u00een
\nplacile de baz\u0103 pentru servere, pl\u0103cile de re\u021bea, dispozitivele de consum, routere, dispozitivele IoT pentru verificarea firmware-ului (identificarea modific\u0103rilor f\u0103cute de malware), furnizarea unui identificator criptografic unic al sistemului (protec\u021bie \u00eempotriva \u00eenlocuirii echipamentului), protec\u021bia cheilor criptografice (izolarea cheilor \u00een cazul \u00een care un atacator ob\u021bine acces fizic la echipament), oferirea de servicii legate de securitate \u0219i men\u021binerea unui jurnal de audit izolat, care nu poate fi editat sau \u0219ters.<\/p>\n
