Infineon Launches SECORA ID Key S USB, a new Security Solution Supporting FIDO2 and PKI for Secured Logical Access

­Infineon Technologies AG is launching the SECORA™ ID Key S USB, a Java Card™-based solution with USB and NFC connectivity for secured authentication and digital signatures. As the first FIDO-certified Level 3+ solution and compliant with CTAP 2.1, the authenticator enables phishing-resistant, passwordless authentication as well as protection against remote software and local hardware attacks. It includes preloaded applets for FIDO authentication, qualified digital signature creation, and PKI functions, while offering comprehensive customization options. Built on Infineon’s innovative system-in-package ID Key S USB hardware platform combined with an open Java Card environment, the end-to-end solution provides maximum flexibility, allowing customers to develop, migrate, and deploy proprietary applets. This supports additional use cases such as physical access, crypto wallets, and software rights management, addressing the needs of enterprises, financial institutions, and government applications.

“The demand for strong, passwordless authentication has never been higher. With SECORA ID Key S USB, we are giving organizations a proven, certified solution that addresses today’s security challenges while being simple enough to deploy at scale across any environment – from enterprise workplaces to government applications and financial institutions,” says Maurizio Skerlj, Senior Vice President and Product Line Manager for Authentication and Identity Solutions at Infineon.

SECORA ID Key S USB is built on Infineon's SLC38 crypto controller and runs a Java Card operating system compliant with Java Card 3.1 and GlobalPlatform v2.3.1. The platform provides 250 kB of user non-volatile memory (NVM), with an additional 64 kB available if the ISO file system applet is removed, as well as 7,392 bytes of free user RAM. It fully supports cryptographic operations, including secured key management and certificate processing for encrypted communication and digital signatures. Based on Infineon's security technology, the solution combines the Infineon ID Key S USB hardware with an open Java Card-based platform, enabling flexibility and scalability for advanced passwordless authentication and identity use cases. The solution is compatible with environments without integrated smart card readers and simplifies deployment within existing IT systems. It also combines hardware-level security with application diversity, meeting the requirements of both businesses and users for scalable, secured authentication.

SECORA ID Key S USB is offered in a specific System-in-Package (SiP) solution, combining the security controller with a USB bridge controller. This streamlined single package with its small form factor size (4 x 4x 0.85mm) enables seamless integration and a compact footprint. This helps reduce the bill of materials and simplifies logistics and inventory management for OEMs alike. To facilitate the integration of the SECORA ID Key S USB, Infineon provides comprehensive development tools, including Java Card development environment and the Infineon Configurator for developing custom applets and personalizing the on-board Java Card OS. In addition, various services are offered, including technical support, training, and consulting, to help customers get the most out of the SECORA ID Key S USB. Infineon is working with several ecosystem partners to develop new use cases and applications for the authentication solution, further expanding its functionality and interoperability.
