Security#

Silicon Labs offers a range of security features depending on the part you are using and your application and production needs. This section provides background on security and how to use the available security features.

• IoT Security Fundamentals: Introduces the security concepts that must be considered when implementing an Internet of Things (IoT) system. Using the ioXt Alliance's eight security principles as a structure, it clearly delineates the solutions Silicon Labs provides to support endpoint security and what you must do outside of the Silicon Labs framework.

• Series 2 and Series 3 Secure Debug: Explains the different debug lock and unlock features available in Series 2 and Series 3 devices and their capabilities.

• Production Programming of Series 2 and Series 3 Devices: Demonstrates how to properly program, provision, and configure Series 2 and Series 3 devices in a production environment.

• Anti-Tamper Protection Configuration and Use: Describes how to program, provision, and configure the Secure Engine anti-tamper module. The anti-tamper module is only available on Secure Vault High and Series 3 Secure Vault devices.

• Authenticating Silicon Labs Devices using Device Certificates: How to authenticate an EFR32 Series 2 device with Secure Vault, using secure device certificates and signatures.

• Secure Key Storage: Explains how to securely "wrap" keys in EFR32 Series 2 devices with Secure Vault, so they can be stored in non-volatile storage.

• Programming Series 2 Devices Using the Debug Challenge Interface (DCI) and Serial Wire Debug (SWD) (PDF): Describes how to provision and configure Series 2 devices through the DCI and SWD.

• Integrating Crypto Functionality Using PSA Crypto Compared to Mbed TLS (PDF): Describes how to integrate crypto functionality into applications using PSA Crypto compared to Mbed TLS.
