Infineon Technologies AG has launched the OPTIGA Authenticate NBT, a high-performance NFC I2C bridge tag for single-tap authentication and secured configuration of IoT devices. It is the only asymmetric cryptography tag for sign and verify operations in the market certified as a Type 4 Tag by the NFC Forum. The solution facilitates ultra-fast and seamless data exchange even with large data volumes. It allows contactless NFC communication between IoT devices and contactless readers such as smartphones. It can be employed for various applications, such as secured configuration of electronic devices without a display, activation of shared mobility vehicles, passive commissioning of unpowered smart light bulbs before installation, and data logging on patient health monitors.
The device supplies superior security with the company's Integrity Guard 32 security architecture and the EAL6+ certification for the hardware and the crypto libraries. The tag supports symmetric and asymmetric cryptographic authentication and pass-through and asynchronous data transfer modes.
The device employs TEGRION hardware and provides a contactless interface speed of up to 848Kbit/s and an I2C interface that supports up to 1Mbits/s, which results in the best performance values, which is especially important for demanding applications. The NFC I2C bridge tag offers 8KB of generous memory to store customer and application-specific configuration information. Also, the high on-chip capacitance enables smaller antenna designs, optimising BOM costs and space requirements.
Samples of OPTIGA Authenticate NBT are available now.
