A Fine-Grained Privacy Preserving
Protocol over Attribute Based Access Control for VANETs IT Convergence and Application
Engineering, Pukyong National University {nkenyele, bayuat, pyhoya, khrhee}@pknu.ac.kr Abstract Vehicle safety related applications which are
drawing increasing attention in public have attracted extensive research both
in academic and industry areas. However, it is assumed that one service is
offered by one provider, thus forcing vehicle drivers to subscribe to several
service providers within limited computation capabilities. In this paper, we present a fine-grained
privacy preserving protocol over attribute access control for VANETs which
allows a service provider to offer a range of safety related services to
vehicle drivers. The vehicles which have appropriate service attributes are
authorized to access the requested services. In order for a vehicle to access
to the authorized services, we propose a fined-grained access control
mechanism based on linear secret sharing scheme. We consider the concept of
an ID-based signature, an attribute based encryption (ABE) and a linear
secret sharing scheme (LSSS) as our building blocks. Keywords: vehicular ad hoc networks (VANETs),
ID-based signature, attribute based encryption, fined grained access
