Practical Threshold RSA Signatures Without a Trusted Dealer

Abstract

We propose a threshold RSA scheme which is as efficient as the fastest previous
threshold RSA scheme (by Shoup), but where two assumptions needed in Shoup's and in
previous schemes can be dropped, namely that the modulus must be a product of safe primes
and that a trusted dealer generates the keys.
