Secure Boot: Secure Right From the Start

This white paper explains how Secure Boot protects embedded systems from manipulation by establishing a cryptographically secured chain of trust from power on to application startup, ensuring that only authenticated firmware and software can run on the device.

What's Inside

• Understand why Secure Boot is a critical foundation for embedded system security
• Learn how a chain of trust protects the system from read-only memory (ROM) loader through bootloader, kernel and root file system
• Discover how public key cryptography and code signing prevent unauthorized firmware execution
• See how neural processing unit (NPU) acceleration and software optimization enable near real time vision processing
• Compare mechanisms such as device mapper (dm) verity and dm crypt for file system integrity and protection
• See how Secure Boot is implemented on NXP i.MX platforms and supported by TQ embedded modules
