Identity-based ring signature scheme under standard model
Yumin Wang · Journal of Communications · 2008
An identity based ring signature scheme using the method of Waters for constructing private key was presented. This scheme is secure in the standard model under the computational Diffie-Hellman assumption. For l members of a ring,the signature consists of l+1 group elements and requires l+1 pairings to verify. It has shorter public parameter size and more efficiency compared with current signature scheme.
