Short Group Signatures
Authors: D. Boneh, X. Boyen, and H. Shacham
Abstract:
We construct a short group signature scheme. Signatures in our scheme
are approximately the size of a standard RSA signature with the same
security. Security of our group signature
is based on the Strong Diffie-Hellman assumption and a new assumption
in bilinear groups called the Decision Linear assumption. We prove security
of our system, in the random oracle model, using a variant of the
security definition for group signatures recently given by Bellare,
Micciancio, and Warinschi.
