Secure Key Management
Silicon Labs provides a mechanism to store your products keys in a secure manner.
Your secret keys must remain secret to maintain the security architecture - having plenty of secure key storage is critical.
Attackers use invasive attacks on a device to extract Flash content and when an attacker learns how to extract keys or content from a device, they use the same attack vector to attack other devices. A Physically Unclonable Function creates a secret, random, and unique key, from individual device imperfections. The PUF-key encrypts all keys in the secure key storage and applications can handle the keys whilst they remain confidential. The PUF Key is generated at startup and is not stored in flash.
