A Forward Secure Multisignature Scheme
Wang Xiao · Chinese Journal of Computers · 2004
A forward secure multisignature scheme is proposed combining the concept of forward security with multisignature. This means that an adversary cannot forge multisignature pertaining to the past even if has gotten the current all signers' keys, that is, previous generated multisignature remains valid. The forward security of the scheme relies on the strong-RSA assumption. Furthermore, the scheme has the shorter time of generating signature since the scheme is constructed based on Schnorr signature.
