Secure Boot Solutions for Embedded Systems

In today’s world, all the smart embedded devices are connected to internet for payment. connectivity, identification and other critical tasks. Therefore, securing your embedded devices from unauthorized access has become more important than ever. A single breach in security can put your thousands or millions devices worldwide at risk.

 At EPTeck, we implement robust hardware and software level security measures to establish a trusted boot chain for your devices. By verifying the authenticity and integrity of every software component loaded during startup, our Secure Boot solutions provide a powerful defense against tampering, unauthorized access, and potential security breaches.

Whether you’re building IoT devices, industrial systems, or other embedded solutions, our Secure Boot service ensures that your products remain secure and reliable from the moment they power on.

How Secure Boot Works?

The chain of trust in the embedded devices boot process ensures that each boot component verifies the integrity of the next boot component, preventing the system from booting any malicious or unauthorized firmware. If a verification fails at any step, the device halts, maintaining security throughout the startup. EPTecks Secure Boot Solution also complements secure store for securing digital keys and user critical data inside the system.

The Root of Trust starts from the vendor-provided ROM code that verifies and executes the signed bootloader. It uses a public key stored in secure memory, like OTP, ensuring the bootloader’s authenticity.

The bootloader, such as U-Boot or Barebox, checks the kernel’s signature with a verified public key before launching, confirming the kernel’s integrity.

The kernel ensures the root file system's integrity by hashing data blocks and verifying them with a root hash, securing the entire file system.

After the root file System is verified and mounted, the init process starts, finalizing the boot process and ensuring the system operates from secure, trusted filesystem.

Server Level Security

Securing the embedded systems using signed Firmware greatly reduces the attack surface. However, the attack on build server can put your signing keys at risk. The hackers can use these signing keys to generate firmware that can run on your embedded device. EPTeck takes care of the Security of build server by storing private keys in some Hardware Security Modules or PKI Infrastructure.

Professional, Solution-Oriented YOCTO BSP Experts

We commissoned epteck to support our inhouse custom STM32MP1 based hardware. They were mostly working on the YOCTO BSP layers, including building secure boot support, YOCTO release upgrades, device tree work. Khalil and his team have always been professional, responsive and knowledgable. I’ve been impressed with the depth of their understanding of YOCTO and BSPs. The conversations were always solution oriented and we achieved our goals in time. I hope to continue to collaborate with them and can only recommend them to other customers.
