We propose a secure threshold signature scheme without trusted dealer. Our construction is based on the recently proposed signature scheme of Waters in EUROCRYPT’05. The new thre...

We present the first aggregate signature, the first multisignature, and the first verifiably encrypted signature provably secure without random oracles. Our constructions derive f...
