New Digital Multisignature Scheme with Distinguished Signing Responsibilities
Luu Hong Dung, Nguyễn Hiếu Minh, Hoang Quoc Viet, Việt Nam · 2010
A multisignature scheme is a digital signature scheme that allows multiple signers to generate a single signature in a collaborative and simultaneous manner. In this paper we first review of the digital multisignature schemes using elliptic curvers and elliptic curve version of the multisignature scheme with distinguished signing responsibilities. Then, we propose a new multisignature scheme with distinguished signing responsibilities. In this scheme, each group member has distinguished signing responsibility and partial contents of the message can be verified without revealing the whole message. Our proposed scheme is more efficient than the scheme reviewed and capable of application in practice.
