Silicon Labs’ Secure Vault IoT Security Solution First to Earn Global PSA Level 3 Certification

Beijing, China – March 18, 2021 – Silicon Labs (also known as Silicon Labs, NASDAQ: SLAB), a leading supplier of chips, software and solutions dedicated to building a smarter, more connected world, officially became the world’s first Silicon innovator certified by PSA for high-level Internet of Things (IoT) software and hardware security protection. PSA Certification, co-founded by Arm, a highly regarded IoT hardware, software and device security program, awarded PSA Level 3 certification for Silicon Labs’ EFR32MG21 wireless SoC with Secure Vault.

This milestone achievement solidifies Silicon Labs’ leadership in protecting the Internet of Things from bad actors. Secure Vault complies with stringent security software and Physical Unclonable Function (PUF) hardware requirements as defined by PSA Level 3 certification, significantly reducing the risk of IoT ecosystem security breaches and mitigating intellectual property damage or counterfeiting Loss of revenue from the product. Specifically, Secure Vault technology has the following features:

· Protection against scalable local and remote software attacks;

Protection against local hardware attacks, which, although historically fewer than software attacks, are on the rise due to the proliferation of inexpensive and easily accessible tools;

· Tested by an independent third-party laboratory, it can effectively prevent attempts to use sophisticated equipment to violate the safety function within a certain period of time.

“As attacks on IoT applications continue to increase and become more sophisticated, it is critical to provide chip-level protection for devices,” said Andy Rose, chief system architect and researcher at Arm. “Silicon Labs is the first to achieve PSA Level 3 certification. is a silicon chip supplier that can provide a proven PSA root of trust and robust protection solutions against a variety of sophisticated hardware and software attacks.”

Matt Johnson, senior vice president of IoT at Silicon Labs, said: “The continued growth of the Internet of Things depends on devices having trusted authenticity and security as they join the ecosystem. PSA Level 3 certification provides IoT device manufacturers and end users The assurance they need to know that their IoT applications effectively protect private information used for authentication and prevent counterfeit or rogue devices from entering their supply chain, thereby avoiding irreparable damage to brands and revenue. Silicon Labs Committed to innovation in chips, software and solutions to ensure the safe and secure growth of the IoT consumers, businesses and industries we serve. We have made strategic investments to become the leading provider of secure IoT wireless solutions and Becoming the first chip innovator in the world to receive PSA’s highest level of security certification is a testament to our success.”

Launched in 2020, Secure Vault is an award-winning suite of advanced features designed to help connected device manufacturers address the ever-evolving and evolving IoT security threats and regulatory pressures. Secure Vault includes its own security kernel, as well as ROM, RAM, and Flash, which contain the core encryption algorithm and True Random Number Generator (TRNG) functionality, secure key management and storage, and physical tamper protection, as well as a , a secure identity protected by the Silicon Labs root certificate chain. In 2020, Secure Vault achieved PSA Level 2 certification and won a Gold Award in the 2020 LEAP Connectivity category. Secure Vault has also received SmartCert certification from the ioXt Alliance for its robust IoT security protection. In October 2020, the ioXt Alliance selected PSA certification as the underlying root-of-trust scheme in its certification program.

The PSA certification program was co-founded by Arm in 2017 to provide a clear framework for securing connected devices, from analysis to security assessment and certification. The framework provides standardized resources to address the growing fragmentation of IoT requirements and removes security barriers in product development. PSA certification provides 3 levels of security assurance, of which PSA Level 3 certification demonstrates a significant commitment to equipment security. Under the PSA Level 3 certification standard, chip vendors need to meet complex protection configuration requirements, which cover robust protection against a range of sophisticated software and physical IoT attack methods.
