It claims to be the only asymmetric cryptography tag for sign and verify operations in the market certified as a Type 4 Tag by the NFC Forum.
OPTIGA Authenticate NBT enables data exchange even with large data volumes. It enables contactless NFC communication between IoT devices and contactless readers such as smartphones.
It can be used 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 prior to installation, and data logging on patient health monitors.
OPTIGA Authenticate NBT offerd security with Infineon’s Integrity Guard 32 security architecture, and the EAL6+ certification for both the hardware and the crypto libraries.
The tag supports both symmetric and asymmetric cryptographic authentication as well as pass-through and asynchronous data transfer modes.
The device uses TEGRION hardware and enables a contactless interface speed of up to 848 Kbit/s and an I2C interface that supports up to 1 Mbits/s.
The NFC I2C bridge tag offers 8 KB of memory to store customer and application-specific configuration information.
In addition, the high on-chip capacitance enables smaller antenna designs, optimizing both BOM costs and space requirements.
