Infineon introduces NFC I2C bridging tags for contactless verification and secure configuration of iot devices

     The number of iot devices is rapidly increasing and being applied to a wide range of industries. As the number of smart devices increases, so does the user's demand for ease of device configuration and pairing. To this end, Infineon Technologies AG has introduced the OPTIGA Authenticate NBT product. This is a high-performance NFC I2C bridging tag product for the implementation of functions such as single point verification and security configuration of iot devices. It is the only label product on the market that uses asymmetric encryption for signature and verification and is NFC Forum Type 4 certified.

     The OPTIGA Authenticate NBT uses NFC (Near Field Communication) technology to facilitate communication between iot devices and smart devices that support contactless card reading, such as smartphones, to achieve the solution required for seamless and high-speed data transfer of large amounts of data in this scenario. OPTIGA™ Authenticate NBT can be used for a variety of applications, such as security configuration of displayless electronic devices, activation of shared vehicles, passive commissioning of smart devices (such as smart light bulbs) prior to installation, and automated sign data logging for portable medical devices (such as health monitors).

     OPTIGA Authenticate NBT uses Infineon's Integrity Guard 32 security architecture with CC EAL6+ certified hardware and library for outstanding security. The label product supports symmetric and asymmetric cryptographic authentication, as well as pass-through and asynchronous data transfer modes.

     Based on TEGRION hardware, OPTIGA Authenticate NBT supports a transfer rate of 848 Kbit/s in non-connected scenarios, and its I2C interface supports a transfer rate of 1 Mbits/s, providing important support for applications requiring high-performance data transmission. The NFC I2C bridge tag provides 8 KB of large memory capacity to efficiently store multiple configuration information for customers and specific applications. In addition, due to the design of high on-chip capacitance, this product can effectively support the realization of small antenna design, and provide assistance for customers in material cost reduction and product space planning requirements.
