Title:
Threshold Ring Signatures Efficient for Large Sets of Signers

Authors: K. Maneva-Jakimoska, G. Jakimoski, M. Burmester

Abstract:

The anonymity provided by the threshold ring signature scheme
proposed by Bresson et al (Crypto’02) is perfect. However, its
complexity is prohibitively large even for relatively small sets
of signers. We propose use of threshold schemes based on covering
designs that are efficient for large groups of signers. The cost we pay is non-perfect anonymity.
