To strengthen security in USB tokens and other authentication devices, Infineon has announced a new USB-based security controller, ID Key S USB. It’s the newest addition to the ID Key family, a line of secure hardware devices. It’s a mix of two controllers in a single package: a security controller (Infineon SLC38) for cryptographic operations and a USB controller for device communication. This system-in-package means fewer parts and simpler product design.
The device supports both USB-only and USB/NFC tokens. This is useful for a range of hardware authenticators like dongles and security keys. It targets the security needs of modern times, offering a login and identity verification system that is more secure and convenient. ID Key S USB is compatible with certificate-based authentication, FIDO (Fast Identity Online), device-bound passkeys, digital signatures, encryption, access control, and hardware wallets. It has a 32-bit CPU based on Arm SecureCore SC300, running at 100 MHz. The RAM is 24 KB, and it has an 800 KB non-volatile memory (SOLID FLASH) to store permanent data like encryption keys and software.
ID Key S USB is compact with dimensions of 4 x 4 x 0.85 mm. It makes a good fit for integration into space-limited token devices like USB dongles. It holds the CC EAL 6+ certification and is compliant with the FIPS 140-3 hardware standard. Cryptographic hardware supports: RSA (up to 4096-bit), ECC (Elliptic Curve Cryptography up to 521-bit), AES (up to 256-bit), Random Number Generator, DES, and 3DES. It comes in a compact PG-VQFN-28 package, suitable for high-volume production and automated assembly. The ID Key S USB is currently available to early access customers through Infineon’s official channels.
