PSA Certified: Making Secure Digital Transformation a Reality
The industry is at a turning point in security. The PSA Certified 2022 Security Report revealed business leaders have placed security at the top of the priority list and are committed to addressing the lag between the rate of digital transformation and the speed of securing the ecosystem.
As the ecosystem prepares to tackle underlying security concerns, research shows that there are some barriers to overcome. In particular, cost remains a barrier to implementation - physical costs, the cost of security experts, and the price of independent evaluation.
Arm first introduced the concept of a IoT security framework in 2017 and is a co-founder of PSA Certified – a framework and an independent third-party evaluation scheme to build-in the right level of device security.
PSA Certified has scaled to become one of the fastest growing, most valued security ecosystems, globally, and continues to break down the barriers to security. Arm remains an active co-founder of PSA Certified and is heavily involved in providing architecture specifications and security resources.
Access five actions that will reduce the cost of security and forge a more powerful connected future with advice from industry experts in the PSA Certified advisory paper.
PSA Certified Benefits
Accelerates the development of secure systems using a trusted approach designed by experts.
Increase access to global markets, thanks to alignment to industry and government standards, plus emerging IoT legislation.
PSA Certified offers an industry-standard measurement on security implementation, checked by independent labs and third parties.
Four Steps To Ease Security Design
The PSA Certified framework was created to help ensure security is designed into a device from the ground up. The four PSA Certified stages guide security implementation for each specific use case:
- Analyze: the evaluation of assets and assessment of threats to define specific security requirements.
- Architect: the security design based on identified security requirements.
- Implement: the process of bringing together hardware and firmware using open source firmware implementations.
- Certify: assurance that products adhere to security requirements and the 10 security goals outlined by PSA Certified.
Check out this white paper for an in-depth explanation of PSA Certified and an overview of the four stages.
Bridging the Gap
As the digital world continues to evolve, a key challenge will be securing the IoT driving the underlying technologies. The PSA Certified 2022 Security Report uncovers insights into IoT industry's perceptions and intentions surrounding security. This year's findings show that 2022 will be a turning point where security becomes a primary concern for business leaders and key barriers to security begin to be resolved.

The Arm Ecosystem: Security Made Simple
Arm puts security at the heart of every connected product. Originally spearheaded by Arm with support from CAICT, ProvenRun, Riscure, SGS Brightsight, TrustCB, and UL, PSA Certified provides a security-by-design scheme that starts with the root of trust and aligns to the cybersecurity requirements of USA, Europe, and China.
Arm is committed to making security easier to achieve using the Arm architecture. We continue to provide industry-leading security specifications and guides, paving the way for a more secure, connected world.
Delivering a seamless software experience across a secure Arm ecosystem, PSA Certified is one of three pillars in both Project Cassini and Project Centauri. PSA Certified plays a central role by uniting the ecosystem under a common security language.
Specifications and Guides
Arm provides security architecture specifications and guides to help architects and engineers develop the necessary hardware and firmware to build a Root of Trust and meet PSA Certified requirements.
PSA Certified APIs
The PSA Certified APIs provide programming interfaces within the device to underlying security services implemented into the silicon root of trust. They ensure application developers can leverage trusted functions while reducing time-to-market and security efforts. The PSA Certified APIs have been available from Arm for many years, and have now been moved into an open public GitHub repository to enable collaboration.
Trusted Firmware provides an open source reference implementation of the PSA Certified guidelines by complying to the platform security architecture specifications and providing reusable components to build in fundamental security functions for devices based on Cortex-M and Cortex-A. The software ensures easy porting to chips and platforms and creates a trusted environment. Delivered in a CMSIS pack, the stack can be easily configured and adapted to custom hardware in several IDEs, including Arm Keil MDK.
