Abstract
Conference Title: 2014 IEEE 80th Vehicular Technology Conference (VTC Fall) Conference Start Date: 2014, Sept. 14 Conference End Date: 2014, Sept. 17 Conference Location: Vancouver, BC, Canada We argue in this paper that while trust management through negotiation performed in IT system might seem appropriate at first sight, it has to be extended to address specific concerns to interoperable environments like the case in Intelligent Transportation Systems - ITS environment. In this context, negotiation does not only depend on trust requirements, but is strongly linked to the security policies as well as to the privacy related attributes shared among entities during communication. This paper discusses what needs to be negotiated in ITS environment and how we can model these negotiation rules in security policies. Besides, it proposes an approach to use the XeNA negotiation framework [1] to negotiate these different types of resources.
