Infineon Expands Its Secure Authentication Portfolio with New ID Key S USB Token

Jul 10,2025

Infineon Technologies AG has unveiled its latest addition to its USB-based hardware authentication portfolio — the Infineon ID Key S USB. This new solution further strengthens the company’s lineup of USB tokens, security dongles, cryptographic keys, and hardware-based identity authenticators.

Designed to address a broad range of USB and USB/NFC authentication applications, the ID Key S USB combines the robust security, performance, and reliability of Infineon’s SLC38 security controller with a highly integrated USB bridge controller. This system-in-package (SiP) solution delivers enhanced flexibility for developers while simplifying implementation and reducing the bill of materials and associated costs.

In an era of increasing cyber threats and the rising need for secure online interactions, demand for reliable hardware-based authentication continues to surge. “As the market shifts toward stronger and more user-friendly authentication methods, we’re seeing rapid adoption of advanced security technologies,” said Maurizio Skerlj, Senior Vice President of Infineon’s Connected Secure Systems Division and Head of the Authentication and Identity Solutions product line. “With ID Key S USB, Infineon is well-positioned to meet this growing demand and deliver a powerful solution that fits a variety of customer needs.”

Designed for Versatile Security Use Cases
The ID Key S USB is engineered to support a wide array of authentication scenarios, including:

• Certificate-based identity verification

• Fast online authentication with device-bound keys (FIDO)

• Secure digital signatures

• Data encryption

• Access control

• Software protection

• Cryptocurrency hardware wallets

At the core of the device lies a 100 MHz 32-bit CPU and 24 kB RAM, enabling rapid and secure execution of embedded applications. With up to 800 kB of non-volatile memory, the device can securely store large amounts of sensitive data, cryptographic keys, software packages, and multiple applications — all while maintaining high operational performance across use cases.

Security is paramount: the ID Key S USB is Common Criteria (CC) EAL 6+ certified, the highest assurance level for commercial security products. It also complies with FIPS 140-3 hardware requirements, allowing customers to pursue FIPS 140-3 certification for their end solutions.

Despite its advanced capabilities, the ID Key S USB maintains a compact 4 x 4 x 0.85 mm footprint, making it ideal for space-constrained hardware tokens and secure mobile form factors.
