摘要：Threshold Multisignature schemes combine the properties of threshold group-oriented signature schemes and Multisignature schemes to yield a signature scheme that allows more group members to collaboratively sign an arbitrary message. The main objective of this paper is to propose such a secure and efficient Multisignature scheme. This paper shows that the proposed scheme eliminates the latest attacks to which other similar schemes are subject. In many applications, a group of members are required generate digital signature. Individual signers remain anonymous, due to the fact that it is computationally hard to derive the individual identities from the group signature. The computational cost for Signature generation and verification is high. Individual signers do not remain anonymous, they are traceable. This ensures accountability, i.e., a participant holds responsible for his contribution in the multisignature. The computational cost is reduced when compared to other schemes. We will use the multisignature in a simple application for sending group messages.
