I would like to know how are achieved PUFs (Physicaly Unclonable Functions) and if there is a way reverse these hardware electronic components ?

Recent papers such as "Invasive PUF Analysis" present techniques to extract information from PUFs but, I would like to better understand the basic principles of PUFs and what are the problems when trying to clone it.

    Check Dmitry Nedospasov's website and presentations. – Ange Nov 15 '13 at 11:13
  • Yes, this is exactly this kind of input I was looking for (and I still want somebody to explain me how PUF is working! :)). Thanks Ange ! – perror Nov 15 '13 at 12:25

If you are looking to better understand the basic principles of PUFs, I would warmly recommend the lecture notes of Boris Skoric. Chapter 5 is all about PUFs: history, examples, applications and entropy. Some of the things presented there are also formalized, which requires a decent level of information theory knowledge.
