Organiza\u021bia non-profit lowRISC, care coordoneaz\u0103 dezvoltarea microprocesorului deschis bazat pe arhitectura RISC-V, a anun\u021bat disponibilitatea primului cip gata pentru produc\u021bia comercial\u0103, construit pe baza platformei deschise OpenTitan, dezvoltat\u0103 ca un proiect colaborativ independent. Proiectul a fost ini\u021bial fondat de Google, dar dup\u0103 transferul c\u0103tre organiza\u021bia lowRISC, companii precum Western Digital, Seagate, Nuvoton Technology, Winbond, Rivos, zeroRISC \u0219i G+D Mobile Security s-au al\u0103turat dezvolt\u0103rii sale. Codul \u0219i specifica\u021biile componentelor hardware asociate proiectului sunt publicate sub licen\u021ba Apache 2.0. <\/p>\n

Spre deosebire de implement\u0103rile existente ale Root of Trust, OpenTitan se dezvolt\u0103 conform concep\u021biei \"securitate prin transparen\u021b\u0103\", ceea ce implic\u0103 disponibilitatea codului \u0219i schemelor, precum \u0219i un proces de dezvoltare complet deschis, ne\u00eengr\u0103dit de furnizori \u0219i produc\u0103tori specifici de cipuri. La baza solu\u021biilor utilizate \u00een OpenTitan stau tehnologii deja utilizate \u00een token-urile USB criptografice Google Titan \u0219i cipurile TPM pentru a asigura un boot verificat, instalate pe servere<\/a> infrastructura Google, precum \u0219i pe dispozitivele Chromebook \u0219i Pixel. <\/p>\n

OpenTitan este o platform\u0103 pentru crearea de componente hardware de \u00eencredere (RoT, Root of Trust), care poate fi utilizat\u0103 acolo unde trebuie garantat\u0103 integritatea hardware-ului \u0219i software-ului sistemului, asigur\u00e2ndu-se c\u0103 p\u0103r\u021bile critice ale sistemului nu au fost compromise \u0219i se bazeaz\u0103 pe cod verificat \u0219i autorizat de produc\u0103tor. Proiectul ofer\u0103 un cadru gata, verificat \u0219i de \u00eencredere, permi\u021b\u00e2nd cre\u0219terea \u00eencrederii \u00een solu\u021biile create \u0219i reducerea costurilor la dezvoltarea chipurilor specializate pentru asigurarea securit\u0103\u021bii. <\/p>\n

Chipurile bazate pe OpenTitan pot fi utilizate \u00een pl\u0103ci de baz\u0103 pentru servere, pl\u0103ci de re\u021bea, dispozitive de consum, routere, dispozitive IoT pentru verificarea firmware-urilor \u0219i componentelor desc\u0103rcabile, precum \u0219i pentru generarea de identificatori unici criptografic pentru sistem (protec\u021bie \u00eempotriva \u00eenlocuirii hardware-ului), protejarea cheilor criptografice (izolarea cheilor \u00een caz de acces fizic al unui atacator la echipament), furnizarea de servicii legate de securitate \u0219i p\u0103strarea unui jurnal de audit izolat, care nu poate fi editat sau \u0219ters. <\/p>\n

OpenTitan include diverse blocuri logice folosite \u00een cipurile RoT, cum ar fi un microprocesor deschis bazat pe arhitectura RISC-V (RV32IMCB Ibex), coprocesoare criptografice, un generator hardware de numere aleatoare, un manager de chei cu suport DICE, un mecanism de stocare securizat\u0103 a datelor \u00een memorie permanent\u0103 \u0219i RAM, tehnologii de protec\u021bie, blocuri de intrare\/ie\u0219ire, instrumente pentru \u00eenc\u0103rcare sigur\u0103 etc. Dispozitivul ofer\u0103, de asemenea, blocuri ce implementeaz\u0103 algoritmi de criptare standard, cum ar fi AES \u0219i HMAC-SHA256, \u0219i un accelerator de opera\u021bii matematice utilizate \u00een algoritmii de lucru cu semn\u0103turi digitale bazate pe chei publice, cum ar fi RSA \u0219i algoritmii pe baza curbelor eliptice.
