The $k$-out-of-$n$ signature is a signature scheme where $k$ real signers
among $n$ signers corporate in signature generation.
Verifiers can check that $k$ real signers have generated the signature,
while they can certify the anonimity of $k$ signers, that is, it is
hidden who have generated the signature.
%Therefore, $k$-out-of-$n$ signature have the property of anonimity to
the signers.
Multi-ring signature is one of the $k$-out-of-$n$ signature constructions.
In this paper, we show that several multi-ring signature schemes do not
satisfy the unforgeability by giving a concrete attack procedure.
Moreover, we point out any adversary of the forgery of the signature
could implement in two types of behavior,
and we propose a multi-ring signature which can be proven secure against
adversary of two types.
The proposed scheme can be shown to be secure for each type of adversary,
by substituting the instance of DLP in the proper parameter which is
introduce in our scheme depending on the signed message and the value of
rings,
corresponding to each type of adversary. |
