Compania Google a prezentat<\/a><\/noindex> platforma OpenSK, care permite crearea de firmware pentru tokenuri criptografice, complet conforme cu standardele FIDO U2F<\/a><\/noindex> \u0219i FIDO2<\/a><\/noindex>. Tokenurile preg\u0103tite folosind OpenSK pot fi utilizate ca autentificatori pentru autentificarea ini\u021bial\u0103 \u0219i cu dou\u0103 factori, precum \u0219i pentru confirmarea prezen\u021bei fizice a utilizatorului.

OpenSK ofer\u0103 posibilitatea de a crea un token personalizat pentru autentificarea cu dou\u0103 factori pe site-uri, care, spre deosebire de solu\u021biile gata f\u0103cute, produse de companii precum Yubico, Feitian, Thetis \u0219i Kensington, este construit pe un firmware complet deschis, disponibil pentru extensii \u0219i audit. OpenSK este pozi\u021bionat ca o platform\u0103 de cercetare pe care produc\u0103torii de tokenuri \u0219i entuzia\u0219tii o pot folosi pentru a dezvolta noi func\u021bionalit\u0103\u021bi \u0219i a promova tokenurile \u00een mase. Ini\u021bial, codul OpenSK a fost dezvoltat ca o aplica\u021bie pentru Tock OS<\/a><\/noindex> \u0219i testat pe pl\u0103cile Nordic nRF52840-DK \u0219i Nordic nRF52840-dongle. <\/p>\n

Pe l\u00e2ng\u0103 software, proiectul ofer\u0103<\/a><\/noindex> modele pentru imprimarea 3D a carcasei USB a cheii bazate pe chipul popular Nordic nRF52840<\/a><\/noindex>, care include un microcontroler ARM Cortex-M4 \u0219i un cryptoaccelerator
\n ARM TrustZone Cryptocell 310. Nordic nRF52840 este prima platform\u0103 de referin\u021b\u0103 pentru OpenSK. OpenSK asigur\u0103 suportul pentru cryptoacceleratorul ARM CryptoCell \u0219i toate tipurile de transport disponibile pe chip, inclusiv USB, NFC \u0219i Bluetooth Low Energy. Pe l\u00e2ng\u0103 utilizarea cryptoacceleratorului, \u00een OpenSK au fost preg\u0103tite, de asemenea, implement\u0103ri separate ale algoritmilor ECDSA, ECC secp256r1, HMAC-SHA256 \u0219i AES256, scrise \u00een Rust.<\/p>\n

Merit\u0103 men\u021bionat c\u0103 OpenSK nu este prima implementare deschis\u0103 a firmware-ului pentru tokenuri cu suport pentru FIDO2 \u0219i U2F, firmware-uri similare dezvolt\u00e2nd proiecte deschise Solo<\/a><\/noindex> \u0219i Somu<\/a><\/noindex>. Spre deosebire de proiectele men\u021bionate, OpenSK este scris nu \u00een C, ci \u00een limbajul Rust, permi\u021b\u00e2nd evitarea multor vulnerabilit\u0103\u021bi care apar din cauza lucrului pe niveluri joase cu memoria, cum ar fi accesarea zonelor de memorie dup\u0103 eliberarea acestora, dereferirea pointerilor nuli \u0219i dep\u0103\u0219irea limitelor bufferului. <\/p>\n

Firmware-ul propus pentru instalare se bazeaz\u0103 pe TockOS<\/a><\/noindex>,
\nun sistem de operare pentru microcontrolere bazate pe Cortex-M \u0219i RISC-V, care asigur\u0103 izolarea sandbox a nucleului, driverelor \u0219i aplica\u021biilor. OpenSK este conceput ca un applet pentru TockOS. Pe l\u00e2ng\u0103 OpenSK, Google a preg\u0103tit \u0219i pentru TockOS o versiune optimizat\u0103 pentru memorie Flash (NVMC) stocare<\/a><\/noindex> \u0219i un set de patch-uri<\/a><\/noindex>. Nucleul \u0219i driverele din TockOS, la fel ca OpenSK, sunt scrise \u00een limbajul Rust.<\/p>\n
