I am new to the security field, i hope you can help me with this issue,
I am designing an access control system based on RFID 13.56 Mhz, and i am using Mifare RC522 IC, which is compatible with the mifare mini, 1k, 4k, ultralight, desfire Ev1 and Mifare Plus passive tags.
Does the selection of the tag type will affect the security of the communication, if i want to rate the compatible tags ascending?
How can such system be attacked, and how to prevent such attacks? and i want to test my system, is there any tools that i can develop to perform such attacks?
How to protect the communication between reader and tag in addition to ISO 14443 ?
how to protect the data on the tag, and the data on the micro-controller that is driving the reader?
Thanks in advance,
