“…However, it is worth note that in practice, it is useful to limit the value of ς to a small number in order to avoid "Sybillike" attacks (DOUCEUR, 2002). In this type of attack one vehicle impersonate a platoon aiming to get some advantage over the system (MOALLA et al, 2012). As a consequence, such a fake platoon could end up receiving preferential treatment from traffic lights programmed to give higher priority to congested roads.…”

Com o aumento da demanda por Sistemas de Transporte Inteligentes (ITSintelligent transportation systems), requisitos de segurança de informação e privacidade são primordiais. Isso levou a muitas propostas visando a criação de uma infraestrutura de chave pública veicular (VPKI-Vehicular Public Key Infrastructure) capaz de atender esses requisitos. Entre estes, o Sistema de Gerenciamento de Credenciais de segurança (SCMS-Security Credential Management System) é particularmente promissor. Ele provê autenticação de dados de uma maneira a preservar a privacidade e também suporta revogação de veículos que apresentem comportamento inadequado. Especificamente, um dos principais benefícios do SCMS é o chamado processo de butterfly key expansion, que emite lotes arbitrariamente grandes de certificados para pseudônimos a partir de única requisição. Embora este protocolo originalmente exija que o veículo forneça dois pares de chaves públicas/privadas separadas para as autoridades de registro, aqui é proposta uma abordagem aprimorada que as unifica em um único par de chaves. Também é mostrado esse ganho de desempenho não causa nenhuma deterioração em termos de segurança, flexibilidade ou escalabilidade quando comparado ao SCMS original. Além das melhorias no protocolo original baseado em curvas elípticas, aqui é apresentada uma versão pós-quântica do protocolo usando a hipótese de segurança R-LWE (Ring Learning-with-errors). Este novo protocolo tem o mesmo formato e características do original, mas usa assinatura e cifração baseada em R-LWE como esquemas subjacentes e operações em reticulados para o processo de emissão de chaves em vez de curvas elípticas.

“…or even to automatically adapt to the new conditions. A detailed risk analysis for in tervehicular communications can be found in [13]. Among these risks, we can cite the eavesdropping on the communications, the emission of fake data to a vehicle in order to trigger an unappropriate reaction, and of course a potential compromission of the ECU responsible for car-to-car communica tions.…”

International audience—Embedded electronic components, so-called ECU (Electronic Controls Units), are nowadays a prominent part of a car's architecture. These ECUs, monitoring and controlling the different subsystems of a car, are interconnected through several gateways and compose the global internal network of the car. Moreover, modern cars are now able to communicate with other devices through wired or wireless interfaces such as USB, Bluetooth, WiFi or even 3G. Such interfaces may expose the internal network to the outside world and can be seen as entry points for cyber attacks. In this paper, we present a survey on security threats and protection mechanisms in embedded automotive networks. After introducing the different protocols being used in the embedded networks of current vehicles, we then analyze the potential threats targeting these networks and describe how the attackers' opportunities can be enhanced by the new communication abilities of modern cars. Finally, we present the security solutions currently being devised to address these problems

In intelligent transport systems, connectivity of vehicle is the main feature for improving services to the driver and passengers. In Electric Vehicle domain, permanent connectivity is paramount in order to compensate both the limited range and to achieve an effective grid inclusion enabling the availability of electric energy everywhere anytime. The objective of this paper is to present the risk on privacy due to the continuous connectivity between EVs and a smart grid. Privacy is composed of different viewpoints such as technical but also legal and socio-ethical.
