Recent Developments on Security and Privacy of V2V & V2I Communications: A Literature Review

In the recent years Intelligent Transportation Systems and associated technologies have progressed significantly, including services based on wireless communications between vehicles (V2V) and infrastructure (V2I). In order to increase the trustworthiness of these communications, and convince drivers to adopt the new technologies, specific security and privacy requirements need to be addressed, using Vehicular Ad Hoc Networks (VANETs). To maintain VANET′s security and eliminate possible attacks, mechanisms are to be developed. In this paper, previous researches are reviewed aiming to provide information concerning matches between an attack and a solution in a VANET environment

Securing PKI Requests for C-ITS systems

<p>Cooperative Intelligent Transportation Systems are rapidly gaining momentum in the scenario of modern wireless communications. Within these environments, messages are exchanged continuously. The latter should be secure and ensure users’ privacy. Public Key Infrastructures (PKIs) represent the major solution to meet security needs. On the other hand, communications between the PKI and the vehicle stations or the Road Side Unit stations should also be secure. Main current security standards do not address and define a complete detailed secure end-to-end mechanism to send requests to the PKI and receive the associated responses. In this paper, we propose a detailed security protocol, based on ETSI security standards, that ensures confidentiality, integrity and authentication. The evaluation of the latter shows its ability in meeting security needs.</p
