Pardon me, but confirmed by who and to whom?

 

Did he tell just you that he’s still standing by his claim, and would he mind re-stating that statement on this list? 😉

There are two ways to design a system. One is to make is so simple there are obviously no deficiencies.

The other is to make it so complex there are no obvious deficiencies.

It was confirmed by multiple sources that Schnörr was indeed the author of the paper.

 

It also appeared that he had uploaded the wrong version of it, and is still standing by his claim.

I say that ePrint upload is a fake.

    Claus Schorr mistakenly uploaded the wrong file, an outdated draft.

 

    He just uploaded the newest file:

    https://eprint.iacr.org/eprint-bin/getfile.pl?entry=2021/232&version=20210303:182120&file=232.pdf

 

    It will surely undergo extreme scrutiny, as it does claim:
