Secure Threshold Order-Specified Multi-signature Scheme in MANET
Yang Muxiang, Hong Mei Fan, Jun Li, Li Su · 2006
Threshold signature schemes are useful in MANET because of the mobility and weak connectivity. Meanwhile, order-specified multi-signature schemes are valuable in some multi-level security systems. To meet such kind of requirements, we proposed a secure threshold order-specified multi-signature scheme based on RSA in this paper. The scheme is designed based on a modified threshold RSA signature scheme and an order-specified. It has a certain extent exact security. Proof is given in the random oracle model and the computational and spatial complexity are presented at the end.
