The ST25DV-I2C BLE out-of-band pairing demonstration firmware shows how NFC can be used to improve the security of BLE connections.
NFC provides an additional communication channel between a Bluetooth® device and an Android™ phone. This extra communication channel is used to exchange data (called out-of-band data) used during the Bluetooth pairing, preventing MITM attacks.
This firmware (STSW-ST25DV004), an Android application and its source code (respectively, STSW-ST25005 and STSW-ST25006), and user manual UM2710 are available on www.st.com.
An STM32WB55 microcontroller (on the MB1355C board) and an X-NUCLEO-NFC04A1 board are required to run the demonstration software.
- Bluetooth® Low Energy (BLE) pairing with OOB (out-of-band) information exchanged through NFC using ST25DV-I2C series Dynamic NFC Tags
- Secure BLE connection
- Secure simple pairing
- Protection against MITM (man-in-the-middle) attacks
