I recently read some articles on EMV and the various ways in which it has been improved over the years. I then read this which shows that it has been possible for some time to exploit EMV via a man in the middle attack. In reading up on how that attack worked (and watching the YouTube video), I heard that it's not possible to copy an EMV chip.
Now I'm not an engineer by any stretch of the imagination, but I really don't understand how someone can be so sure that it's not possible to copy a chip? I mean it's a chip, it's there on my card for all of the world to see... I'm not debating the merits of doing this at all, my interest was peaked at the fact that people claim that a little bit of metal cannot be copied...
If you answer this by saying, it can/can't be copied please provide some references, as I'm looking to further my understanding of how this 'miracle' of modern day security really works! :)
Also, I have Googled my ass off trying to find more information, I even read the EMV 4.2 specification, but there is nothing which explains WHY it is truly secure.
I've tried to tag this question as best as possible, but I don't know enough about the topic to find all of the right tags... Anyway, please provide me with any insight you might have :-)
