If I understand your question correctly then you are asking about the advantages of using this stand alone PUF project vs. something like a microcontroller with integrated PUF such as...

> @myndcryme Apart from these, are there any advantages related to performance and all ? I don't have hands on experience with other puf products/implementations so I can't really answer...

I have also had failures reconstructing the key but succeed reconstructing the key in the past. IIRC, reconstruction only succeeded when the micro sdcard was formatted with the "official" sd...

Seems like you have done everything correctly so there must be an issue with the code. I have a guess of why it is failing so I'll take a look.

@jafeelv - Reconstruction is working for me, however I am having an issue with the PUF-encrypt step (I'll discuss another time). Are you seeing "error" in your output when performing...

16GB formats FAT32 so that is not the problem. Just to be clear, no PUF key is displayed in the terminal, correct?

@jafeelv Bear with me, I am still working on identifying the cause but made good progress today.

@jafeelv I figure once your sd card is initialized you get nothing more because the SD.open() call is failing. This has been happening to me not in reconstruction, but in...
