What level of Secure Vault protection is supported by the Lyra (22) and Lyra 24 series?

Answer

Secure Vault is Silicon Labs' security solution integrated into their 32-bit microcontrollers to protect devices from a wide range of security threats once deployed in the field. By assigning each device a unique digital fingerprint, Secure Vault ensures the secure management of cryptographic keys. It also prevents unauthorized firmware from running by verifying that only authenticated code is executed during the boot process. Additionally, Secure Vault offers protection against physical tampering, restricts access to debug ports, and defends against side-channel attacks, such as those targeting power consumption patterns … and much more!

By default, three different security levels are available: Base (SVB), Mid (SVM), and High (SVH), allowing you to choose the right level of protection that best suits your application and device needs. The Lyra (22) series is equipped with Secure Vault "Mid" for robust security, while the 24 series provides maximum protection with Secure Vault "High".
