Abstract:

   This document describes Sigma Protocols for proving knowledge of
   preimages of linear maps in prime-order elliptic curve groups.  These
   are sometimes also called _Maurer Proofs_, or _proofs of knowledge of
   a preimage of a group homomorphism_.

   Examples include zero-knowledge proofs for discrete logarithm
   relations, ElGamal encryptions, Pedersen commitments, and range
   proofs.
