I have an information security class this semester, and I need to write a paper evaluating how secure NFC and RFID technology is.
A lot of questions previously asked here are at least 3 years old, and I'm sure computing power within NFC and RFID tags have increased since then, so I'd like to hear about more recent developments in this area.
I'm aware there are solutions out there for symmetric and asymmetric encryption, but the only problem is, I can't find any good explanations on how they work. Especially the asymmetric solutions.
I would also appreciate it if you could point me to any potential weaknesses within NFC and RFID systems that I could research.
