The True You.
Many IoT Devices have unique identities (UID's) but the UID is public and can be copied. Copies are a problem for account and product authenticity which can threaten a business model and the security of a user account. Silicon Labs products have unique device certificates generated during IC production. The device certificate includes a public key which is signed by a Silicon Labs private key which is a secret that never leaves the secure key storage on the chip.
The secure element uses an attestation command that allows it to prove itself to a cloud by validation against the Silicon Labs certificate chain. Developers of Silicon Labs products can create their own device certificates during their production.
Our Product Security Incident Response Team (PSIRT) is responsible for ensuring the vulnerabilities discovered in our products are mitigated and communicated responsibly. If you detect a security threat, let us know.
