Membership in citizen groups
Article history: Received 27 November 2007 Available online 8 November 2008 JEL classification: C73 D71 We analyze the coordination problem of agents deciding to join a group that uses membership revenues to provide a discrete public good and excludable benefits. The public good and the benefits are jointly produced, so that benefits are valued only if the group succeeds in providing the public...
متن کاملAnonymous Authentication of Membership in Dynamic Groups
We present a series of protocols for authenticating an individual’s membership in a group without revealing that individual’s identity and without restricting how the membership of the group may be changed. In systems using these protocols a single message to the authenticator may be used by an individual to replace her lost key or by a trusted third party to add and remove members of the group...
متن کاملConstructive membership in black-box groups
We present an algorithm to reduce the constructive membership problem for a black-box group G to three instances of the same problem for involution centralisers in G. If G is a simple group of Lie type in odd characteristic, then this reduction can be performed in (Monte Carlo) polynomial time.
متن کاملMembership Authentication in Dynamic Face Groups
This paper presents a novel method to authenticate an individual’s membership in a group without revealing the individual’s identity and without restricting how the member of the group may be changed. It has the ability to authenticate membership and is robust to cope with the variations of both the group size and the group member of membership.
متن کاملRedefining animal signaling: influence versus information in communication
Researchers typically define animal signaling as morphology or behavior specialized for transmitting encoded information from a signaler to a perceiver. Although intuitively appealing, this conception is inherently metaphorical and leaves concepts of both information and encoding undefined. To justify relying on the information construct, theorists often appeal to Shannon and Weaver’s quantitat...
