A Fully Distributed Proactively Secure Threshold-Multisignature Scheme Abstract: Threshold-multisignature schemes combine the properties of threshold group-oriented signature schemes and multisignature schemes to yield a signature scheme that allows a threshold t or more group members to collaboratively sign an arbitrary message.

In contrast to threshold group signatures, the individual signers do not remain anonymous, but are publicly identifiable from the information contained in the valid threshold-multisignature. The main objective of this paper is to propose such a secure and efficient threshold-multisignature scheme.

The paper uniquely defines the fundamental properties of threshold-multisignature schemes and shows that the proposed scheme satisfies these properties and eliminates the latest attacks to which other similar schemes are subject.

The efficiency of the proposed scheme is analyzed and shown to be superior to its counterparts. Article :. Date of Publication: 05 March DOI: Need Help?

My Account Careers Downloads Blog. Project Enquiry. Threshold-multisignature schemes mix the properties of threshold cluster-oriented signature schemes and multisignature schemes to yield a signature scheme that allows a threshold t or a lot of group members to collaboratively sign an arbitrary message. In distinction to threshold cluster signatures, the individual signers do not stay anonymous, but are publicly identifiable from the data contained within the valid threshold-multisignature. The main objective of this paper is to propose such a secure and efficient threshold-multisignature theme. The paper uniquely defines the fundamental properties of threshold-multisignature schemes and shows that the proposed theme satisfies these properties and eliminates the latest attacks to that different similar schemes are subject. The efficiency of the proposed theme is analyzed and shown to be superior to its counterparts.

Threshold Signature

Threshold signatures are digital signatures where signers can establish groups such that only certain subsets of the group can produce signatures on behalf of the group. The collection of subsets that are authorized to produce signatures is called the access structure of a threshold scheme. More particularly, a t,n -threshold signature scheme is a digital signature scheme where any t or more signers of a group of n signers can produce signatures on behalf of the group. In general, a threshold signature does not reveal the actual group members that have cooperated to produce it. Multisignatures are threshold signatures with the additional feature that they reveal the identities of the group members who produced them [ 2 , 12 ].
