I would like to know "ST25TA02K-P" TAG IC will support any encryption/cryptographic modes to secure the data??Or any other TAG from ST support that feature. Basically i want to secure the TAG data.
To this day, the ST25TA02K IC does not provide a data encryption mode.
To better help and find an IC matching your need, can you please clarify
which of the two following use cases is the closest to yours :
1) data encryption during RF transaction
2) read/write access protection through a crypted authentication protocol
For our application (identifying passive TAG using NFC Reader), this would be the nearest - read/write access protection through a crypted authentication protocol on TAG. Requirement: TO secure the data inside the passive TAG
Among the products available as of today, we identified the ST23 and ST31 as potential candidates to implement your use case.
Thanks for suggesting few new parts. But my application is not EMVco and the mentioned IC's are MCU "ST23 & ST31" .
I would like to know NFC TAG IC's which support some cryptograph protocol.I would like to design my system in secure mode, no one can understand what data is transfering (unknown format using some cipher key). Communication from TAG IC (from ST) to NFC READER IC (ST25R3914)
No passive NFC Tag IC supporting cryptographic tools is currently available in ST25 family ( pure tag portfolio)
Despite ST23 and ST31 being EMVCO products, I forgot to mention that our suggestion is to use them in card emulation mode to implement your use case.
Sorry for the misunderstanding.
>>Basically i want to secure the TAG data.
Crypt and sign the data so it doesn't exist in plain-text within the tag, in-flight, etc.
Retrieving data ...
