Although current estimates depict steady growth in Internet of Things (IoT), many works portray an as yet immature technology in terms of security. Attacks using low performance devices, the application of new technologies and data analysis to infer private data, lack of development in some aspects of security offer a wide field for improvement. Th...
Chapter
Security and privacy aspects are crucial for the acceptance of IoT environments. Accordingly, this chapter will focus on new approaches to enable end user to better control and protect their privacy and personal data. In particular, it will describe the work carried out in the context of the EU project SMARTIE, which proposed a user-centric platfor...
Article
Precision Agriculture (PA), as the integration of information, communication and control technologies in agriculture, is growing day by day. The Internet of Things (IoT) and cloud computing paradigms offer advances to enhance PA connectivity. Nevertheless, their usage in this field is usually limited to specific scenarios of high cost, and they are...

The chapter presents an overview of the eight that are part of the European IoT Security and Privacy Projects initiative (IoT-ESP) addressing advanced concepts for end-to-end security in highly distributed, heteroge- neous and dynamic IoT environments. The approaches presented are holistic and include identification and authentication, data prote...
Conference Paper
The Internet of Things (IoT) offers an incredible innovation potential for developing smarter applications and services. However, today we see solutions in the development of vertical applications and services reflecting what used to be the early days of the Web, leading to fragmentation and intra-nets of Things. To achieve an open IoT ecosystem of...

We study the problem of multihop routing in vehicular ad hoc networks (VANET). IEEE 802.11p and other vehicular network standards advocate vehicles to issue periodic broadcast messages at regular intervals called beacons. Beacons include among other information geographic coordinates of the vehicle, heading, speed, etc. Thus, most VANET routing sol...
Conference Paper
We address the problem of efficiently revoking certificates of malicious and compromised nodes in vehicular networks. As in previous work, our focus is making sure that vehicles receive the new list of revoked certificates (CRL) before they can be compromised. Unlike previous solutions, our work revolves around the idea of making use of existing ca...
Conference Paper
Full-text available
The possibility of connecting vehicles to fixed IP networks through roadside units (RSUs) or even access gateways is seen as a very interesting alternative to fully infrastructure-less VANETs. However, getting access to those fixed networks must be controlled and only authorized users should be able to use those RSUs or gateways. However, that auth...
