TITLE:
Full-Domain Subgruop Hiding and Constant-Size Group Signatures

ABSTRACT:
We give a short constant-size group signature scheme, which we prove fully
secure under reasonable assumptions in bilinear groups, in the standard
model. We achieve this result by using a new NIZK proof technique, related
to the BGN cryptosystem and the GOS proof system, but that allows us to
hide integers from the full domain rather than individual bits.
