Research in vehicular ad hoc networks (VANETs) has evolved considerably over the last years. Security and privacy in VANETs have recently appealed special interest in the research community. In this paper we overview the main privacy concepts and explain why this concept is fundamental for wide adoption of VANETs. A set of privacy requirements for VANETs(More)
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(More)
In current e-banking systems, millions of consumers are now able to conduct financial transactions using a wide range of mobile devices; this growth exposes the system not only to the set of known threats that are now migrating from traditional PC-based e-banking to the mobile-based scenario, but, to emerging threats specifically targeting mobile devices.(More)
Every day, hundreds or even thousands of computers are infected with financial malware (i.e. Zeus) that forces them to become zombies or drones, capable of joining massive financial botnets that can be hired by well-organized cyber-criminals in order to steal online banking customers' credentials. Despite the fact that detection and mitigation mechanisms(More)
Vehicular Ad-Hoc NETworks (VANETs) improve road safety by preventing and reducing traffic accidents, but VANETs also raise important security and privacy issues. A common approach widely adopted in VANETs is the use of Public Key Infrastructures (PKI) and digital certificates in order to enable authentication and confidentiality, usually relying on a large(More)
Privacy-enhancing attribute-based credential (Privacy-ABC) technologies use different cryptographic methods to enhance the privacy of the users. This results in important practical differences between Privacy-ABC technologies, especially with regard to efficiency, which have not been studied in depth, but is necessary for assessing their suitability for(More)
