Hsinchu, October 31st, 2025<\/em><\/strong> \u2013<\/em>\u2013 PUFsecurity, an eMemory subsidiary and global leader in PUF-based security solutions, today announced that its PUF-based Root-of-Trust IP (PUFrt) has been successfully integrated into Silicon Labs\u2019 latest Series 3 Secure Vault\u2122 wireless SoCs, which have achieved the industry\u2019s first PSA Certified Level 4 accreditation. This successful integration sets a new benchmark for secure wireless connectivity, positioning PUFsecurity and Silicon Labs as leaders in establishing Level 4 as the new standard for trusted connected devices.<\/p>\n\n\n\n

PSA Certified Level 4: Raises the Bar for Chip Security by Design<\/strong><\/p>\n\n\n\n

PSA Certified Level 4<\/a> is the most rigorous level of the global PSA framework, requiring resilience against invasive physical attacks, side-channel leakage, and fault injection. Achieving this certification involves months of destructive lab testing, ensuring the silicon itself resists nation-state-class adversaries. Only a handful of products worldwide have attempted to reach this threshold. By embedding PUFrt, Silicon Labs\u2019 Series 3 Secure Vault\u2122 wireless SoCs are anchored with a strong hardware-based trust foundation that meets these stringent requirements.<\/p>\n\n\n\n

PUFrt<\/a> brings together essential security primitives including Physical Unclonable Function (PUF), secure OTP, and advanced anti-tamper protection. With these elements built directly into silicon, PUFrt enables silicon providers to accelerate their path to certification at the highest levels while ensuring robust device protection throughout the product lifecycle.<\/p>\n\n\n\n
