\textrm{Slightly more formally, we define blind signatures as a quadruple
of algorithms:}
\begin{itemize}
\item $ KeyGen(1^\lambda)$: Generates a verification/signing key pair
$(K^{\pub}, K^{\priv})$.
- \item $Blind(m, b, K_x^{\pub})$: Takes a message $m$, blinding factor
$b$, and verification key $K_x^{\pub}$ of the signer $X$ and computes the
blinded message $\overline{m}$.
- \item $BlindSign(K_x^{\priv}, \overline{m})$: Takes secret signing key
$K_x^{\priv}$ and blinded message $\overline{m}$ and computes the blind
signature $\overline{\sigma}$.
- \item $Unblind(\overline{\sigma}, b, K_x^{\pub})$: Takes blind signature
$\overline{\sigma}$, blinding factor $b$ and verification key $K_x^{\pub}$ of
the signer $X$, and returns the unblinded signature $\sigma$ (or $\bot$).
+ \item $Blind(m, b, K^{\pub})$: Takes a message $m$, blinding factor $b$,
and verification key $K^{\pub}$ of the signer and computes the blinded message
$\overline{m}$.
+ \item $BlindSign(K^{\priv}, \overline{m})$: Takes secret signing key
$K^{\priv}$ and blinded message $\overline{m}$ and computes the blind signature
$\overline{\sigma}$.
+ \item $Unblind(\overline{\sigma}, b, K^{\pub})$: Takes blind signature
$\overline{\sigma}$, blinding factor $b$ and verification key $K^{\pub}$ of the
signer, and returns the unblinded signature $\sigma$ on message $m$ (or $\bot$).
