Issue
Fixes #411
Description
Changed the computation of the Chaum-Pederson proofs to more efficient versions saving two modular exponentiations per proof. Still computes the exact same proofs and verification stays the same.
(Note, there is a typo in the Word document that is attached to the issue: the alternative for the proof of an encryption of zero needs to compute
v1 = (v + c1*R) mod q.)Testing
Run Chaum-Pedersen tests.
