A Paillier Based Threshold Signature Scheme
Chuan Chen, Kewei Lv, Yixin Zhu · 2009
Based on Paillier public key cryptosystem, a new threshold signature scheme is presented, which under RSA(N,N) assumption, is unforgeable and robust in random oracle model. The scheme enjoys the following properties: signature share gen- eration and verification are non-interactive; and the size of an in- dividual signature share is bounded by a constant times the size of the modulus N 2 .
