Infineon Technologies AG is expanding its portfolio of USB tokens, dongles, security keys, and other hardware authenticators with the introduction of the new Infineon ID Key family. The latest member, the ID Key S USB, is a highly secured and versatile product developed for a wide range of USB- and USB/NFC-token devices and applications. It combines the security, performance, and reliability of the company's SLC38 security controller with a USB bridge controller in one single package. It is a unique system-in-package solution that allows high flexibility and simplifies complex application deployments while lowering the BoM and related costs. Certified to the highest security levels, it supports a range of use cases, including certificate-based authentication, Fast Identity Online (FIDO) authentication with device-bound passkeys, digital signatures, encryption, access control, software protection, and cryptocurrency hardware wallets.
The increasing necessity for secured online transactions and the growing threat of cyberattacks have created a surge in demand for secured and hardware-backed authentication solutions. "As the market shifts towards more secured and convenient authentication methods, we see a growing trend towards the adoption of advanced security solutions," said Maurizio Skerlj, senior vice president and product line head Authentication and Identity Solutions at Infineon's Connected Secure Systems Division. "With the ID Key S USB, we are well-positioned to address this trend and provide our customers with a robust solution that meets their needs."
The ID Key S USB provides a range of key features that support its secured and versatile design and supplies a comprehensive array of features. A 32-bit CPU drives its high-performance capabilities clocked at 100MHz and a large 24kB RAM, enabling ultra-fast and secured execution of applications and delivering exceptional operating system performance for a wide range of use cases. The device also provides sufficient memory, with non-volatile memory sizes of up to 800kB providing ample storage for large amounts of data, cryptographic keys, software, and multiple applications. Furthermore, the ID Key S USB has achieved the highest security levels, with certification to CC EAL 6+ (high) and compliance with FIPS 140-3 hardware needs, allowing customers to apply for FIPS 140-3 certification for their product. The ID Key S USB features a compact footprint of 4mm x 4mm x 0.85mm, making it excellent for integration into space-critical token devices.
