ST25DV-I2C NFC dual interface tag cryptography demonstration

[BHamm]

Hi,

There is a [YouTube video provided by STMicroelectronics](https://www.youtube.com/watch?v=e4Jji8fZU8E) titled "ST25DV-I2C NFC dual interface tag cryptography demonstration".

It vaguely references an Android app and ST eval board firmware, but doesn't say exactly what they're called. I don't see any mention of a crypto example listed in any of the software packages found under "tools and software", nor in any of the source code when I download all of the available packages. When I download the ST Tag app for my phone, I don't see any option of actually communicating with an eval board in the Android app, it appears entirely focused on communicating with the ST25DV.

Could someone point me to the crypto example? I'm ultimately looking for an example of the ST25DV Fast Transfer Mode (Mailbox), and establishing a secure connection.

Thanks.

Dear BHamm,

The ST25DV-I2C Cryptography Demonstration webpage is under creation and should be available shortly on st.com, in early 2020.

Eagerly awaiting

Is it possible to give an update on when this may be released? In a week, a month, 6 months, no longer planned?

The webpage for this demo is available here: https://www.st.com/content/st_com/en/campaigns/st25dv-i2c-dual-interface-nfc-tag-cryptography-demonstration.html

The demonstration board is not yet available on st.com, but samples can be delivered through your local ST sales (https://www.st.com/content/st_com/en/contact-us.html).

The same demonstration will soon be available for the STM32L476RG-NUCLEO plus the X-NUCLEO-NFC04A1 NFC shield (the firmware for this platform will be online in a couple of weeks).

Alternatively, one can reproduce the setup from the video by using parts available on st.com:

• the Motherboard from the ST25R3916-DISCO kit: https://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/st25-nfc-rfid-eval-tools/st25-nfc-rfid-eval-boards/st25r3916-disco.html
• The Daughter board from the ST25DV-DISCOVERY kit: https://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/st25-nfc-rfid-eval-tools/st25-nfc-rfid-eval-boards/st25dv-discovery.html

Sorry for the inconvenience.

I will update this topic once the STM32 NUCLEO firmware for this demo is available on the web.
