====== Security of vehicular communications ======

A transportation system is an environment that
poses several challenges with regard to technology
requirements. Because of the large number and high speed of
Vehicles, technologies for Vehicular Communications (VC) and Intelligent Transportation Systems (ITS) must be scalable and robust
enough to cope with these characteristics. Architectures
and protocols for ITS thus need to be deeply examined
and assessed for performance and scalability before their
final adoption as part of a standard ITS framework.

===== Why Security for vehicular communications is important =====

Security and protection of business assets within the ITS
framework is also a viral part without which the whole
system can not be deployed in real life. Security is
needed to provide authentication, integrity protection
and confidentiality of information within the ITS
framework. Without it, malicious entities may alter the
normal operations of ITS applications and cause faults
that can lead to disasters. On the other hand, a proper
management of authorization for services and accounting
is necessary in order for service providers to be able
to deploy commercial services such as Internet access and
multimedia streaming.


===== Research on security of vehicular communications =====








==== IEEE 1609.2 ====

//IEEE trial-use standard for wireless access in vehicular
environments - security services for applications and management messages//

Defines a public-key-infrastructure (PKI)-based approach for securing messages sent in a vehicle-to-vehicle and vehicle-to-infrastructure fashion. The standard is not freely available yet you can purshase it [[http://webstore.ansi.org/RecordDetail.aspx?sku=IEEE+Std+1609.2-2006&source=google&adgroup=ieee&keyword=ieee%201609.2-2006&gclid=CJDA-6uS_JYCFRQbewodIAxIXg|here]]. Some information on IEEE 1609.2 can be found [[http://bbcr.uwaterloo.ca/~pinhan/ECE628/COMMAG_VANET.pdf|here]].



==== The Sevecom Project ====

[[http://www.sevecom.org/|SeVeCom]] (Secure Vehicular Communication) is an EU-funded project that focuses on providing a full definition and implementation of security requirements for vehicular communications.

The project delivarable [[http://www.sevecom.org/Deliverables/Sevecom_Deliverable_D2.1_v2.0.pdf|Sevecom_Deliverable_D2.1_v2.0]] explains the use of public key cryptography with with //pseudonymity// to provide security services while preserving privacy.
