Practical Threshold RSA Signatures Without a Trusted Dealer
Ivan B. Damgård
November 2000 |
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
