In today's highly digital society, security controllers have become the core force for securing personal data and digital identity. They are widely embedded in critical devices such as e-passports, ID cards, payment cards, and smartphones, protecting the privacy and security of billions of people around the world. As a technology pioneer in this field, Infineon Technologies AG has shipped more than 10 billion security controllers based on the Integrity Guard security architecture, an important milestone that underlines the worldwide recognition and impact of its architecture.
Fifteen years ago, Infineon pioneered the Integrity Guard architecture in the first 16-bit security controller in its SLE78 family and made it the core of its security portfolio. The architecture is known for its high security, with a dual-CPU design and hardware-level error detection to protect against increasingly sophisticated security threats. In response to the growing security challenges and compliance requirements, Infineon is introducing a new generation of security controllers, the TEGRION SLC27G, which integrates the upgraded Integrity Guard 32 architecture and provides enhanced security in the areas of identification, payment and authentication.

"The cumulative shipment of the Integrity Guard architecture exceeds the global population, which is a testament not only to our technological leadership, but also to the importance of security controllers in today's world." "The TEGRION SLC27G is our response to the growing need for high-level security solutions in the context of a sharp increase in cyberattacks, accelerated digitalization and tightening regulations such as the European Union's Cyber Resilience Act (CRA)," said Maurizio Skerlj, Senior Vice President, Identity & Authentication, Infineon's Connected Security Systems Division.”
With a design that supports dual interfaces and contactless applications, the TEGRION SLC27G is built for long-term security and will meet the challenges of identification, authentication and payment in the future. At its core, it is based on an enhanced Arm® v8-M 32-bit instruction set, optimized for security, energy efficiency, computing performance and easy integration.
The next-generation Integrity Guard 32 architecture features efficient error detection and a self-checking, dual-core CPU system. The architecture supports flexible upgrades to adapt to evolving security requirements in the future and helps accelerate the security certification process for products. Its superior performance and high reliability make it ideal for products that comply with high regulatory standards such as the CRA, while also being proactive against quantum computing security threats.
At present, TEGRION SLC27G is receiving authoritative certification from the German Federal Information Security Agency (BSI), with the goal of achieving Common Criteria EAL6+ certification. This process reaffirms Infineon's continuous investment and commitment to advancing information security around the world.
