“…However, the CSS approach, as presented in [27], is defined over cryptographic pairings limited to the symmetric setting. Symmetric pairings have the disadvantage that they are only viable for practical implementations using obsolete security levels (for example, 80-bit) [28].…”

“…Although the CSS scheme as proposed in [27] is recommended for VANETs security, its definition in the symmetric setting limits its applicability in real scenarios such as smartphones and other smart devices. According to practical realizations of pairing-based encryption [28,36,37], the symmetric pairing is realized by using type A elliptic curves, only efficient for obsolete security levels (80-bit security level or less) according to standards such as NIST [38]. Currently, the recommended security levels are for 112, 128, 192, or 256 bits.…”

“…A way to use increased security levels in pairing-based cryptography is to use the asymmetric setting, usually realized with type F elliptic curves. In [28], the asymmetric setting for pairings was proposed and evaluated in the context of data security in cloud storage. The results achieved showed the efficiency of using asymmetric pairings, in terms of higher security and lower overhead in running time and memory requirements.…”

Vehicular ad-hoc Networks (VANETs) are recognized as a cornerstone of Intelligent Transportation Systems (ITS) to enable the exchange of information among vehicles, which is crucial for the provision of safety-related and entertainment applications. However, practical useful realizations of VANETs are still missing, mainly because of the elevated costs and the lack of a final standardization. In this regard, the feasibility of using smartphones as nodes in VANETs has been explored focusing on small-scale deployments to mainly validate single-hop communication capabilities. Moreover, existing smartphone-based platforms do not consider two crucial requirements in VANETs, namely, multi-hop communication and the provision of security services in the message dissemination process. Furthermore, the problem of securing message dissemination in VANETs is generally analyzed through simulation tools, while performance evaluations on smart devices have not been reported so far. In this paper, we aim to fill this void by designing a fully on-device platform for secure multi-hop message dissemination. We address the multi-hop nature of message dissemination in VANETs by integrating a location-based protocol that enables the selection of relay nodes and retransmissions criteria. As a main distinction, the platform incorporates a novel certificateless cryptographic scheme for ensuring data integrity and nodes’ authentication, suitable for VANETs lacking of infrastructure.
