The proliferation of IoT devices is accelerating, making them integral to every industry. However, the increasing number of smart devices demands a simpler user experience for device configuration and pairing. To address this, Infineon Technologies has introduced the OPTIGA Authenticate NBT, a high-performance NFC I2C bridge tag designed for single-tap authentication and secure configuration of IoT devices. According to Infineon, it is unique in the market as the only asymmetric cryptography tag for sign and verify operations certified as a Type 4 Tag by the NFC Forum.
OPTIGA Authenticate NBT facilitates ultra-fast and seamless data exchange, even with large data volumes, enabling contactless NFC communication between IoT devices and contactless readers like smartphones. It is suitable for various applications, including the secure configuration of electronic devices without displays, activation of shared mobility vehicles, passive commissioning of unpowered smart light bulbs prior to installation, and data logging on patient health monitors.
The tag provides enhanced security with Infineon’s Integrity Guard 32 security architecture and EAL6+ certification for both hardware and crypto libraries. It supports symmetric and asymmetric cryptographic authentication, as well as pass-through and asynchronous data transfer modes.
Using TEGRION hardware, the device offers a contactless interface speed of up to 848 Kbit/s and an I2C interface supporting up to 1 Mbits/s, ensuring optimal performance for demanding applications. The NFC I2C bridge tag includes 8 KB of memory to store customer and application-specific configuration information. Additionally, the high on-chip capacitance allows for smaller antenna designs, reducing both BOM costs and space requirements.
