Individual skill
security-updates
Secure boot and firmware update workflows for Zephyr RTOS. Covers MCUboot integration, production image signing, DFU protocols (MCUmgr), fail-safe rollback mechanisms, and mbedTLS crypto basics. Trigger when implementing over-the-air (OTA) updates, securing the boot process, or managing cryptographic keys.

# Zephyr Security & Updates
Build production-ready, secure embedded systems using Zephyr's modular security stack and MCUboot bootloader.
## Core Workflows
### 1. MCUboot Integration
Set up the secure bootloader and define fail-safe flash partitions.
- **Reference**: **[mcuboot_integration.md](references/mcuboot_integration.md)**
- **Key Tools**: `CONFIG_BOOTLOADER_MCUBOOT`, `fixed-partitions`, Devicetree.
### 2. Image Signing
Ensure firmware integrity with production-grade digital signatures.
- **Reference**: **[image_signing.md](references/image_signing.md)**
