What does hardware-rooted authentication mean?
Last reviewed 5 Sept 2026 · Review due 5 Mar 2027
Short answer
Hardware-rooted authentication means authentication proofs depend on credentials or operations protected by hardware security environments rather than software-only secrets. For Keyra, company declaration places current implementations on SIM, eSIM and iSIM for hardware-verified security, extending earlier Cyber One Card hardware approaches.
How it works
A relying party issues a challenge; a security application in a protected environment performs a cryptographic operation; the verifier checks the result against policy and trust configuration. Exact algorithms and key sizes are not asserted here without engineering confirmation.
Limitations & conditions
- Hardware rooting is not the same as proving legal identity.
- Not every phone or carrier exposes the same capabilities.
- Company declaration is not an independent security assessment.
