We propose a straightforward technique to provide peer-to-peer security in mobile networks. We show that far from being a hurdle, mobility can be exploited to set up security associations among users. We leverage on the temporary vicinity of users, during ...
Vehicular networks are very likely to be deployed in the coming years and thus become the most relevant form of mobile ad hoc networks. In this paper, we address the security of these networks. We provide a detailed threat analysis and devise an appropriat ...
Wireless sensor networks are already deployed in numerous occasions. As this technology matures towards wider adoption, security will become an increasingly important requirement. However, resource and cost constraints for the low-complexity sensor nodes r ...
The author focuses on the cryptographic protection of e-passports, working from the assumption that even if people can peacefully live with their e- passports, what sort of cryptography technology is involved here? Can e- passport holders protect their pri ...
Current document archives are enormously large and constantly increasing and that makes it practically impossible to make use of them efficiently. To analyze and interpret large volumes of speech and text of these archives in multiple languages and produce ...
Protocol narrations are a widely-used informal means to describe, in an idealistic manner, the functioning of cryptographic protocols as a single intended sequence of cryptographic message exchanges among the protocol’s participants. Protocol narrations ha ...
We introduce C, a practical provably secure block cipher with a slow key schedule. C is based on the same structure as AES but uses independent random substitution boxes instead of a fixed one. Its key schedule is based on the Blum-Blum-Shub pseudo-random ...
RFID systems makes it possible for a server to identify known tags in wireless settings. As they become more and more pervasive, people privacy is more and more threatened. In this talk, we list a few models for privacy in RFID and compare them. We review ...
Effective and robust operations, as well as security and privacy are critical for the deployment of vehicular ad hoc networks (VANETs). Efficient and easy- to-manage security and privacy-enhancing mechanisms are essential for the wide-spread adoption of th ...
Security is at the core of any communication system and, in particular, of wireless (radio) networks. In this thesis, we focus on three important security aspects in the framework of wireless networks: selfish (noncooperative) behavior at the Medium Access ...
