I'm new to RFID technology and cryptography. So, I'm trying to apply light weight cryptography in RFID tags as a part of my project.
I'm already able to read and write information in some passive RFID tags. But I'm looking for a programmable RFID tag similar to a smart card. Basically I want to send some data to the tag and the tag itself encrypts the data and stores it in its memory. When I want to read the data, it decrypts it and sends it to the reader.
I've searched all over the internet and it isn't helping much. Can someone give any suggestions on where can I find such card and how can I program it?
