Silicon Labs' SiXG301 Achieves World's First PSA Level 4
Imagine your phone or smart devices have a super strong lock to keep bad guys out.
Silicon Labs made this super lock, called Secure Vault, for their devices.
It's like getting the highest grade in a security test, showing it can fight off tricky attacks.
This helps companies make devices that are safe from hackers.
The new standard is called PSA Level 4, and it means the lock is super tough.
The company worked with experts to prove how strong the lock is.
This is important because there are rules around the world to ensure our devices are secure.
Silicon Labs' SiXG301 SoC achieved the world's first PSA Level 4 certification for its Series 3 Secure Vault security subsystem.
This certification, the highest level by PSA Certified, validates Silicon Labs' leadership in IoT security.
PSA Level 4 validates resilience against advanced physical attacks on embedded devices.
Silicon Labs collaborated with Keysight Technologies to validate the security of the SiXG301.
The certification helps device makers align with global regulations, including the EU's RED and US Cyber Trust Mark.
