Welcome to the resource topic for 2004/311

Hierarchical Group Signatures

Authors: Marten Trolin, Douglas Wikstrom


We introduce the notion of \emph{hierarchical group signatures}. This
is a proper generalization of group signatures, which allows multiple
group managers organized in a tree with the signers as leaves. For a
signer that is a leaf of the subtree of a group manager, the group
manager learns which of its children that (perhaps indirectly) manages
the signer.

We provide definitions for the new notion and construct a scheme that
is provably secure given the existence of a family of trapdoor

We also present a construction which is relatively practical, and
prove its security in the random oracle model under the strong RSA
assumption and the DDH assumption.
