| dc.description.abstract | Cooperative Intelligent Transport Systems (C-ITS) enable vehicles and
infrastructure to exchange information and provide users with an enhanced
situation overview. It can provide early warning in potentially
dangerous situations, and help increase safety and efficiency on European
roads. This thesis explores the use of Public Key Infrastructure (PKI)
in a Cooperative Intelligent Transport System, and how it can be used
to achieve authentication within the system. The first part of the thesis
consists of a theoretical presentation of C-ITS and PKI. The overall structure
of the trust hierarchy is discussed before the technical specifications
and requirements of the system are introduced.
The second part describes an experimental implementation of a PKI in a
C-ITS test network. By creating an ITS certificate hierarchy, and modifying
the configuration of the Dynniq ITS units, message authentication
was successfully introduced to the network. The certificate hierarchy was
generated using both OpenSSL and itssec, where the use of the itssec tool
proved successful. Multiple configurations were tested, and the results
were analyzed using supplied applications and Wireshark. After the
results were verified, the PKI was expanded to include an Authorization
Authority. The use of an HTTP file-server and the MQTT protocol
were explored in order to handle network authentication and certificate
distribution. Both options were assessed as viable candidates for more
extensive testing in the future. | |
