Romu USB Development Board (RP2354A) · avance · Utilisez les capacités de sécurité du RP2354A pour créer une authentification sans mot de passe robuste.
Hardware: Romu board, Linux/macOS environment with libfido2, FIDO2-compatible PC. 2. Environment: Clone 'tinyusb' and RP2354-compatible 'FIDO2' stack. Configure RISC-V toolchain if needed for secondary cores. 3. Security: Enable TrustZone in linker config to isolate private keys in secure zone. Use integrated encrypted storage peripherals. 4. Code: Implement CTAP2 commands (Client to Authenticator Protocol). Handle user interaction via Romu's single button to confirm sensitive actions. 5. RGB LED: Configure LED for status (solid blue: ready, blinking blue: waiting for interaction, red: error). 6. Compile: Compile firmware with security flags enabled. 7. Flashing: Flash via BOOTSEL as before. 8. Verification: Use 'fido2-token' tool to list devices and perform web authentication test. 9. Deepening: Integrate side-channel attack countermeasures by randomizing wait times.
