Sherman S. M. Chow, Lucas C. K. Hui, S. M. Yiu
2005 Lecture Notes in Computer Science  
The spontaneity of these schemes is desirable for ad-hoc groups such as mobile ad-hoc networks. In this paper, we present an identity based (ID-based) threshold ring signature scheme.  ...  In threshold ring signature schemes, any group of t entities spontaneously conscript arbitrarily n − t entities to generate a publicly verifiable t-out-of-n signature on behalf of the whole group, yet  ...  Group-oriented signature schemes [9] enable an entity of a group to produce a signature on behalf of the group.  ...
