On the Black-Box impossibility of multi-designated verifiers signature schemes from ring signature schemes
From the work by Laguillaumie and Vergnaud in ICICS’04, it has been widely believed that multi-designated verifiers signature scheme (MDVS) can be constructed from ring signature schemes in general. However, in this article, somewhat surprisingly, we prove that it is impossible to construct an MDVS...
