| Threat | How PS300B Defends | |--------|-------------------| | (probing, side‑channel) | Secure element is FIPS‑140‑2 L3 certified; active tamper sensors zeroize keys on breach. | | Replay Attack | All challenges are nonce‑based ; timestamps embedded; signatures include a device‑specific counter. | | Brute‑Force Password | Password hashing uses Argon2id with high memory cost; rate‑limiting enforced at hardware level. | | Man‑in‑the‑Middle | All traffic encrypted with TLS 1.3; mutual authentication prevents rogue servers. | | Firmware Tampering | Signed firmware updates (ECDSA‑P‑256) verified by the SE; any mismatch aborts boot. | | Supply‑Chain Compromise | Manufacturer provides attestation certificates ; customers can verify the device’s provenance via a public CRL. | ps300b key id password exclusive
