    Vehicular Ad-Hoc NETworks (VANETs), a pillar for the Internet of Vehicles, aim to improve road safety by preventing and reducing traffic accidents. While VANETs offer a great variety of safety and infotainment applications, there remain a number of security and privacy challenges, such as, user profiling and vehicle tracking, which, must be addressed. This paper contributes with a framework to address security and privacy issues in VANETs. The proposed framework consists of i) an inter-domain authentication system able to provide a near realtime certificate status service, ii) a mechanism to quantitatively evaluate the trust level of a CA and establish a on-the-fly interoperability relationship, and iii) a privacy enhancing model that addresses privacy in terms of linkability. © 2014 IEEE.

    Today, almost every environment (e.g. airports, home, office, etc.) are populated with a high number of heterogeneous devices like smart-phones, sensors, laptops, tablets or hotspots. Taking advantage of the different communications capabilities that these devices have researches have been studying how to make people collaborate in spontaneous or dynamic groups to sharing photos, discuss topics, among others. However, this plethora of devices sharing "something" opens the doors to new potential threats putting in risk important personal data or misuse of device resources. Therefore, these environments require new mechanisms able to ensure that devices are conducted safely, and that are able to detect and inform about any anomalies that might occur during an interaction. Although vulnerabilities currently present in ubiquitous devices are quite similar to those in personal computers. The attention given to improve safety has not been enough, especially in the case of malware in mobiles devices, which has been overlooked, mainly due to the large number of malware samples, the sophistication in obfuscation techniques and the internet access constraints which make detection techniques such as those based on signatures, not sufficient. Thus, in this work we analyse current techniques for detecting unwanted data in pervasive environments, and introduce new approaches that model the behaviour among devices in order to detect anomalies related to two scenarios: critical infrastructures and smartphone devices.

    The ever increasing diversity and mobility of devices have originated a marked rise in ubiquitous resources; a great number of collaborative applications could be exploited just by employing an efficient ubiquitous resource management mechanism. The CARM (Composable-Adaptive Resource Management) middleware-based architecture provides a flexible infrastructure where personal devices create seamlessly on demand interconnections links to share ubiquitous resources. In this article we address CARM's security challenges and to overcome these we propose the CARM Authorization (CARMA) module; in CARMA each user acts as an Attribute Authority (AA) responsible of issuing Attribute Certificates (ACs) and defining for each resource a set of policy-based authorization decisions; CARMA's Alerting System (AS) allows users to work in a collaborative mode by warning others of malicious nodes even when no infrastructure is available. This research mainly describes ongoing work towards a proof-of-concept implementation in the given scenarios. Our proposal enforces security considering the bandwidth efficiency and therefore enhancing the dynamic resource management experience in ubiquitous environments.

    Ubiquitous environment's research has evolved considerably over the last years. The wide range of mobile devices, their high diversity and mobility have raised a variety of challenges being resource management a predominant, and therefore attracting special attention in the research community. The Composable-Adaptive Resource Management (CARM) middleware library provides a exi- ble infrastructure where personal devices create seamlessly on-demand interconnections links to share ubiquitous resources. In this paper we present a CARM interesting use case, consisting of an improved audio listening experience by sharing a high quality audio resource. A proof-of-concept implementation is provided, and a testbed comprised of two CARM enabled mobile phones with Bluetooth connectivity making use of remote device's audio resource is described. Our approach demonstrates the importance and usability of enhancing the dynamic resource sharing experience without altering the bandwidth efficiency.

    Presently heterogeneous devices provided with several communications interfaces are everywhere, with this, we are increasingly coming in contact with ”shared” computer-enhanced devices such as cars, portable media players, or home appliances, commonly called ubiquitous computing environments. These environments require special properties that traditional computing does not support, such as a proper resource management which plays an important role in pervasive computing where adaptation and dynamic reconfiguration of resources take place. This work presents a new adaptive resource management approach that supports adaptation for the required resources. We use a component-based model to abstract system’s ubiquitous resources in a transparent and uniform way to the applications.
