Automatising such process is intended to provide with such effectiveness. However, current enforcement practices do not achieve this goal, as they usually have weaknesses regarding the reliable identification of the offender, the immediacy of feedback after the violation, and the completeness of the offence description. Intelligent Transportation Systems (ITSs) technologies may be introduced to contribute on these issues. To enable such integration, a complete model of this process must be built. Based on the VERA2 model and the Spanish traffic legislation, in this work it is proposed an enhanced model that identifies the stakeholders, the process entities, the data at stake and their interchanges. Its suitability to represent current enforcement systems (particularly the Spanish ESTRADA and the French CSA) is evaluated. Furthermore, based on this model, the integration of ITS-related technologies is analysed, as well as their suitability compared to current approaches.

These communication networks allow data interchanging. In this way, more and better information is provided to drivers, thus achieving a better road safety. Information security is critical in these scenarios, as human lives are at stake. Particularly, spreading false data should be prosecuted, so sender identification and authentication is needed. However, it could allow vehicle tracking. In this way, privacy protection must also be achieved. In this work, mechanisms to fulfill this authentication-privacy compromise are analyzed.

Uno de los problemas principales es el diseño y la implementación de sistemas que posibiliten a los usuarios la gestión del control de acceso. A este respecto, pero en el contexto de las RSW, se han identificado una serie de requisitos. Sin embargo, en la literatura, los trabajos existentes sólo satisfacen parcial o completamente algunos de ellos. En este artículo, se propone primero un modelo de control de acceso, SoNeUCONABC, el cual extiende el modelo UCONABC, junto con la especificación de un mecanismo que lo implementa. En segundo lugar, se proporcionan directrices para el establecimiento de mecanismos que, desplegados sobre SoNeUCONABC, satisfagan todos los requisitos.

Users may use multiple WBSNs to satisfy their requirements. Besides, operations such as the creation of accounts or the establishment of groups, are repeated in all of them, being a tedious issue. To address this matter, this paper proposes a protocol, based on the UMA core protocol and the FOAF project, to attain interoperability and reusability of resources, identity data and access control policies across different WBSNs. Moreover, an evaluation and a security analysis are presented.
