In Ch 4:

In order to enhance readability:

Variables (Keys, Numbers, ..) should be visibly different than
Functions ( Encrypt, Decrypt, Sign, Blind, Unblind, Hash, DH-Keygen, ..)
It would be nice to the reader, to list all your functions in one place.

Don't write E_x(..) for encryption with key x and blinding with blinding factor x.
One Function, one Symbol.

Currently you require Taler to use Elliptic Curves.
Does the crypto concept really enforce this,
or is it just a detail from the current implementation?
Afaiu its just a detail.

Dear all,

I've just concluded another major round of edits to the Taler paper
which details the cryptography and key concepts behind Taler.

The current plan is to submit it to an academic conference with a
15-page limit (excluding references and appendices) soon. I'd really
appreciate any feedback you may have (including questions / comments
about things that are simply insufficiently clear).

The paper's source is also in the mint Git. As the original e-mail
didn't go through the list like 3x with the attachment, I've now
also uploaded the PDF to http://grothoff.org/christian/taler-draft.pdf
(FYI: Richard was responding on-list to the e-mail with the same file
attached).


Happy hacking!

Christian
