Secure Vault™ is an industry-leading suite of state-of-the-art security features that address escalating Internet of Things (IoT) threats, greatly reducing the risk of IoT ecosystem security breaches and the compromise of intellectual property or revenue loss from counterfeiting. Specifically, Secure Vault technology:
A Physically Unclonable Function (PUF) to generate a unique digital fingerprint value every time the chip is booted.
The Secure Boot has the capability to prevent roll-back attacks where cyber criminals try to force the MCU to a previous version with a known vulnerability.
Tamper Protection is a very effective way to prevent a hacker from performing sophisticated local attacks. In addition to tamper based on external switches, we offer tamper based on frequency, temperature, voltage and EMF.
Devices have been able to lock debug ports for some time, resulting in a manufacturer being unable to troubleshoot the device if it ever fails. With Secure Debug, we’ve fixed that problem.
Our communication products are often connected on a PCB via a serial interface to a host MCU. Secure Link provides a means of encrypting this interface with a key exchange per session with new keys on each power cycle.
The Root of Trust Secure Loader, a multi-stage bootloader with authentication, checks at each stage with our Immutable Hardware Root of Trust, a separate Secure Engine security subsystem with its own ROM, Flash and RAM.
One of the greatest benefits of Secure Vault is that it can provide a “Secure Identity,” and with that identity, you can perform a Secure Attestation at any time during the life of the product.
DPA is a black box attack called side-channel attacks, a way to mathematically study stray emissions from the chip and derive the secret keys used during cryptography.
Secure Vault TRNGs meet the most stringent security requirements, including NIST SP 800-90A/B and newer C requirements.
As attacks on IoT applications continue to rise and grow in complexity, the importance of securing devices at the chip level remains crucial. Silicon Labs is the first silicon provider to achieve PSA Certified Level 3 status, demonstrating a proven PSA Root of Trust and a solution that offers substantial protection against an extensive range of sophisticated software and hardware attacks.Andy Rose | Chief System Architect and Fellow | Arm
