Compania Google a anun\u021bat \u00eenceputul utiliz\u0103rii chipset-urilor bazate pe platforma deschis\u0103 OpenTitan \u00een dispozitivele Chromebook. Chromebook-urile au devenit primele dispozitive comerciale disponibile, echipate cu OpenTitan. De asemenea, \u00een acest an, Google inten\u021bioneaz\u0103 s\u0103 implementeze sisteme server \u00een centrele sale de date folosind OpenTitan. Produc\u021bia \u00een mas\u0103 a chipset-urilor este organizat\u0103 de compania Nuvoton. De asemenea, s-a men\u021bionat \u00eenceperea lucrului la a doua versiune a chipset-ului, care va permite utilizarea algoritmilor de criptare post-quantic\u0103 ML-DSA \u0219i ML-KEM pentru o \u00eenc\u0103rcare \u0219i o acreditare sigur\u0103, implement\u00e2nd metode de criptografie bazate pe solu\u021bionarea problemelor din teoria re\u021belelor.

\"\u00cen<\/center> <\/p>\n

Proiectul OpenTitan ofer\u0103 o platform\u0103 pentru crearea componentelor hardware de \u00eencredere (RoT, Root of Trust), utilizate acolo unde este necesar\u0103 asigurarea integrit\u0103\u021bii st\u0103rii componentelor hardware \u0219i software ale sistemului. OpenTitan a fost fondat de Google \u00een 2018, dar \u00een 2019 a fost transferat unei organiza\u021bii non-profit, lowRISC, dup\u0103 care au aderat la dezvoltarea sa companii precum Western Digital, Seagate, Nuvoton Technology, Winbond, Rivos, zeroRISC \u0219i G+D Mobile Security. Codul \u0219i specifica\u021biile componentelor hardware asociate cu proiectul au fost publicate sub licen\u021ba Apache 2.0. Solu\u021biile utilizate \u00een OpenTitan se bazeaz\u0103 pe tehnologii deja utilizate \u00een token-urile USB criptografice Google Titan \u0219i chipset-urile TPM pentru a asigura o \u00eenc\u0103rcare verificat\u0103, instalate pe servere<\/a> infrastructura Google, precum \u0219i pe dispozitivele Chromebook \u0219i Pixel. <\/p>\n

Spre deosebire de implement\u0103rile existente ale Root of Trust, OpenTitan se dezvolt\u0103 conform conceptului \u201esecuritate prin transparen\u021b\u0103\u201d, care implic\u0103 accesibilitatea codului \u0219i schemelor, precum \u0219i aplicarea unui proces de dezvoltare complet deschis, independent de furnizori \u0219i produc\u0103tori specifici de chipuri. OpenTitan a devenit prima implementare deschis\u0103 a Root of Trust disponibil\u0103 pe pia\u021b\u0103, av\u00e2nd suport pentru un mecanism de \u00eenc\u0103rcare sigur post-cuantic, bazat pe utilizarea algoritmului de generare a semn\u0103turilor digitale SLH-DSA (Sphincs+), rezistent la atacurile efectuate cu computere cuantice. <\/p>\n

Chipurile bazate pe OpenTitan pot fi utilizate \u00een pl\u0103cile de baz\u0103 ale serverelor, pl\u0103cile de re\u021bea, dispozitivele de consum, routere \u0219i dispozitivele Internet of Things pentru a verifica firmware-ul \u0219i componentele \u00eenc\u0103rcate (protec\u021bie \u00eempotriva modific\u0103rii p\u0103r\u021bilor critice ale sistemului), pentru generarea identificatorilor unici criptografic pentru sistem (protec\u021bie \u00eempotriva \u00eenlocuirii echipamentului), pentru furnizarea de servicii legate de securitate, pentru protec\u021bia cheilor criptografice (izolarea cheilor \u00een cazul \u00een care un atacator ob\u021bine acces fizic la echipament) \u0219i pentru p\u0103strarea unui jurnal de audit izolat, care nu poate fi modificat sau \u0219ters. <\/p>\n

OpenTitan include blocuri logice solicitate \u00een cipurile RoT, cum ar fi un microprocesor deschis bazat pe arhitectura RISC-V (RV32IMCB Ibex), coprocesoare criptografice, un generator hardware de numere aleatorii, un manager de chei cu suport DICE, un mecanism de stocare sigur\u0103 a datelor \u00een memorie permanent\u0103 \u0219i RAM, tehnologii de protec\u021bie, blocuri de intrare\/ie\u0219ire \u0219i componente pentru bootare sigur\u0103. Dispozitivul de asemenea furnizeaz\u0103 blocuri cu implementarea algoritmilor standard de criptare, cum ar fi AES \u0219i HMAC-SHA256, \u0219i un accelerator pentru opera\u021biuni matematice utilizate \u00een algoritmi pentru lucrul cu semn\u0103turi digitale bazate pe chei publice. <\/p>\n
