Democratic Group Signatures with Threshold Traceability
Dong Zheng, Xiangxue Li, Changshe Ma, Kefei Chen, and Jianhua Li
Abstract
Recently, democratic group signatures(DGSs) particularly catch our
attention
due to their great flexibilities, \emph{i.e}., \emph{no
group manager}, \emph{anonymity}, and \emph{individual
traceability}. In existing DGS schemes, individual traceability says
that any member in the group can reveal the actual signer's
identity from a given signature. In this paper, we formally describe
the definition of DGS, revisit its security notions by strengthening
the requirement for the property of traceability, and present a
concrete DGS construction with
