Security and Privacy Issues in Vehicular Named Data Networks: An Overview

Table 1

Comparison of host-centric and information-centric models.

Aspect	Host-centric model	Information-centric model
Addressing	(1) Host addresses	(1) Content name
	(2) DNS for host resolution	(2) No DNS required
Routing	(1) Sends packets to the destination address	(1) Uses Interest packets to fetch the data
	(2) Stateless data plane	(2) Stateful data plane
	(3) Point-to-point connectivity	(3) Supports multipoint connection
	(4) Maintains one routing table	(4) Maintains three tables: FIB, PIT, and CS
	(5) Routing is based only on the next hop information	(5) FIB table contains multiple-hop information
Security	(1) Secures the communication channel	(1) Secures the content (content-based security)
Caching	(1) No caching concept	(1) Buffers data packets and reuses them
Mobility	(1) Resends packets to destination addresses	(1) Uses in-network caching and fetches data packets from the most convenient cache point
