Providing Security Robustness with PSA Certified Level 3

The First Silicon Certified to Protect Devices from Complex Hardware and Software Attacks

Leading silicon, software, and solutions company, Silicon Labs, is strengthening its approach to security to protect its customers from the increasingly sophisticated attacks on Internet of Things (IoT) devices. It has become the first company in the world to be awarded PSA Certified Level 3 status, which it received for its implementation of Secure Vault™ technology. Silicon Labs say that their award-winning suite of state-of-the-art security features helps to protect connected products against remote scalable software attacks and attempts to compromise the hardware. In turn, that reduces the risk to the device makers, consumers, organizations, and industries that are relying on its technology.

The continued growth of the IoT depends on trusting that devices are authentic and secure when they join ecosystems. Security certifications like PSA Certified Level 3 give IoT device makers and end users the assurances they need to know their IoT applications are protecting their secret identities used for authentication and prevent counterfeit or rogue devices from entering their supply chain, which can cause irreparable harm to brands and revenue.

At the heart of Silicon Labs’ approach is an immutable hardware Root of Trust (RoT), which provides a foundation of security that device makers can build on. That means you do not have to be a security expert to build robust security into your device.

What is a Root of Trust?

A Root of Trust (RoT) is the part of a processor where all secure operations are performed, it has hardware protection and is separate from the non-secure processing environment which can be accessed more widely. Examples of secure operations in the RoT could include secure key storage, cryptography and attestation. A RoT is crucial to ensuring a device’s integrity and crucial to ensuring the integrity and security state of that device can be determined by any other device or service it connects to.
