Forward secure secret sharing-multisignature scheme
YU Zhao-ping · Computer Engineering and Applications Journal · 2008
A forward secure secret sharing-multisignature scheme using bilinear pairings based on the strong-RSA assumption is proposed.The security of this scheme is analyzed.In this scheme,the partial signature and the group signature are forward secure,valid group signatures can be easily produced only if all participants pool their secret shares.The validity of the partial signature and the group signature can be verified.
