HetDAPAC: Distributed Attribute-Based Private Access Control with Heterogeneous Attributes. (arXiv:2401.13653v1 [cs.IT])
cs.CR updates on arXiv.org arxiv.org
Verifying user attributes to provide fine-grained access control to databases
is fundamental to an attribute-based authentication system. In such systems,
either a single (central) authority verifies all attributes, or multiple
independent authorities verify individual attributes distributedly to allow a
user to access records stored on the servers. While a \emph{central} setup is
more communication cost efficient, it causes privacy breach of \emph{all} user
attributes to a central authority. Recently, Jafarpisheh et al. studied an
information theoretic formulation of the \emph{distributed} …
