 \begin{abstract}
 David Chaum's original RSA blind sgnatures provide information theoretic
 anonymity for customers' purchases.  In practice, there are many schemes
-that weaken this to provide properties.  We describe a refresh protocol
-for Taler that provides customers with post-quantum anonymity.
-It replaces an elliptic curve Diffe-Hellman operation with a unique
-hash-based encryption scheme for the proof-of-trust via key knoledge
-property that Taler requires to distinguish untaxable operations from
-taxable purchases.
