Firma Google przedstawi\u0142a<\/a><\/noindex> platforma OpenSK, umo\u017cliwiaj\u0105ca tworzenie oprogramowania uk\u0142adowego dla token\u00f3w kryptograficznych, w pe\u0142ni zgodnych z normami FIDO U2F<\/a><\/noindex> i FIDO2<\/a><\/noindex>. Tokeny przygotowane za pomoc\u0105 OpenSK mog\u0105 by\u0107 u\u017cywane jako uwierzytelniacze do jednolitych i dwuetapowych metod uwierzytelniania, a tak\u017ce do potwierdzania fizycznej obecno\u015bci u\u017cytkownika. Projekt zosta\u0142 napisany w j\u0119zyku Rust i rozpowszechniany<\/a><\/noindex> na licencji Apache 2.0.<\/p>\n

OpenSK umo\u017cliwia tworzenie w\u0142asnego tokena do dwuetapowego uwierzytelniania na stronach internetowych, kt\u00f3ry w przeciwie\u0144stwie do gotowych rozwi\u0105za\u0144 wydawanych przez producent\u00f3w takich jak Yubico, Feitian, Thetis czy Kensington, oparty jest na w pe\u0142ni otwartym oprogramowaniu uk\u0142adowym, dost\u0119pnym do rozbudowy i audytu. OpenSK pozycjonuje si\u0119 jako platforma badawcza, kt\u00f3r\u0105 producenci token\u00f3w i entuzja\u015bci mog\u0105 wykorzysta\u0107 do rozwijania nowych mo\u017cliwo\u015bci i popularyzacji token\u00f3w w\u015br\u00f3d szerszej publiczno\u015bci. Oryginalnie kod OpenSK zosta\u0142 opracowany jako aplikacja dla Tock OS<\/a><\/noindex> i przetestowany na p\u0142ytach Nordic nRF52840-DK oraz Nordic nRF52840-dongle. <\/p>\n

Opr\u00f3cz oprogramowania, projekt obejmuje s\u0105<\/a><\/noindex> modele do druku na drukarce 3D obudowy USB-klucza opartego na popularnym chipie Nordic nRF52840<\/a><\/noindex>, kt\u00f3ry zawiera mikrokontroler ARM Cortex-M4 oraz akcelerator kryptograficzny
\n ARM TrustZone Cryptocell 310. Nordic nRF52840 jest pierwsz\u0105 platform\u0105 referencyjn\u0105 dla OpenSK. W OpenSK zapewniona jest obs\u0142uga akceleratora kryptograficznego ARM CryptoCell oraz wszystkich dost\u0119pnych rodzaj\u00f3w transportu, w tym USB, NFC i Bluetooth Low Energy. Opr\u00f3cz wykorzystania akceleratora kryptograficznego, w OpenSK r\u00f3wnie\u017c przygotowano odr\u0119bne implementacje algorytm\u00f3w ECDSA, ECC secp256r1, HMAC-SHA256 oraz AES256, napisane w Rust.<\/p>\n

Nale\u017cy zauwa\u017cy\u0107, \u017ce OpenSK nie jest pierwsz\u0105 otwart\u0105 implementacj\u0105 oprogramowania uk\u0142adowego dla token\u00f3w z obs\u0142ug\u0105 FIDO2 oraz U2F, podobne oprogramowanie rozwijaj\u0105 otwarte projekty Solo<\/a><\/noindex> i Somu<\/a><\/noindex>. W por\u00f3wnaniu do wspomnianych projekt\u00f3w, OpenSK jest napisane nie w C, lecz w j\u0119zyku Rust, co pozwala unikn\u0105\u0107 wielu luk bezpiecze\u0144stwa, kt\u00f3re wyst\u0119puj\u0105 z powodu niskopoziomowej pracy z pami\u0119ci\u0105, takich jak dost\u0119p do obszaru pami\u0119ci po jego zwolnieniu, dereferencja wska\u017anik\u00f3w null oraz przekroczenie granic bufora. <\/p>\n

Oprogramowanie przeznaczone do instalacji opiera si\u0119 na TockOS<\/a><\/noindex>,
\nsystem operacyjny dla mikrokontroler\u00f3w opartych na Cortex-M i RISC-V, zapewniaj\u0105cy izolacj\u0119 sandboxow\u0105 dla rdzeni, sterownik\u00f3w i aplikacji. OpenSK jest przedstawiony jako aplet dla TockOS. Opr\u00f3cz OpenSK Google przygotowa\u0142 r\u00f3wnie\u017c wersj\u0119 TockOS zoptymalizowan\u0105 dla pami\u0119ci Flash (NVMC) przechowywanie<\/a><\/noindex> i zestaw poprawek<\/a><\/noindex>.
