TL;DR: This work proposes a VANET key management scheme based on Temporary Anonymous Certified Keys (TACKs), which efficiently prevents eavesdroppers from linking a vehicle's different keys and provides timely revocation of misbehaving participants while maintaining the same or less overhead for vehicle-to-vehicle communication as the current IEEE 1609.2 standard.
Abstract: Vehicular Ad Hoc Networks (VANETs) require a mechanism to help authenticate messages, identify valid vehicles, and remove malevolent vehicles. A Public Key Infrastructure (PKI) can provide this functionality using certificates and fixed public keys. However, fixed keys allow an eavesdropper to associate a key with a vehicle and a location, violating drivers' privacy. In this work we propose a VANET key management scheme based on Temporary Anonymous Certified Keys (TACKs). Our scheme efficiently prevents eavesdroppers from linking a vehicle's different keys and provides timely revocation of misbehaving participants while maintaining the same or less overhead for vehicle-to-vehicle communication as the current IEEE 1609.2 standard for VANET security.

TL;DR: Interactive RFID-enhanced museum exhibits let visitors continue their scientific exploration beyond the museum's walls, but museums must still help them understand the technology and address their data privacy concerns.

TL;DR: This work examines the difficulty of collecting profile and graph information from the popular social networking website Facebook and describes several novel ways in which data can be extracted by third parties, and demonstrates the efficiency of these methods on crawled data.
Abstract: Preventing adversaries from compiling significant amounts of user data is a major challenge for social network operators. We examine the difficulty of collecting profile and graph information from the popular social networking website Facebook and report two major findings. First, we describe several novel ways in which data can be extracted by third parties. Second, we demonstrate the efficiency of these methods on crawled data. Our findings highlight how the current protection of personal data is inconsistent with user's expectations of privacy.

TL;DR: This paper proposes FindU, the first privacy-preserving personal profile matching schemes for mobile social networks, and proposes novel protocols that realize two of the user privacy levels, which can also be personalized by the users.
Abstract: Making new connections according to personal preferences is a crucial service in mobile social networking, where the initiating user can find matching users within physical proximity of him/her. In existing systems for such services, usually all the users directly publish their complete profiles for others to search. However, in many applications, the users' personal profiles may contain sensitive information that they do not want to make public. In this paper, we propose FindU, the first privacy-preserving personal profile matching schemes for mobile social networks. In FindU, an initiating user can find from a group of users the one whose profile best matches with his/her; to limit the risk of privacy exposure, only necessary and minimal information about the private attributes of the participating users is exchanged. Several increasing levels of user privacy are defined, with decreasing amounts of exchanged profile information. Leveraging secure multi-party computation (SMC) techniques, we propose novel protocols that realize two of the user privacy levels, which can also be personalized by the users. We provide thorough security analysis and performance evaluation on our schemes, and show their advantages in both security and efficiency over state-of-the-art schemes.

TL;DR: The authors describe several mobile agent systems to illustrate different approaches designers have taken in addressing challenges in addressing agent mobility, naming, security issues, privacy and integrity, authentication, authorization and access control, and fault tolerance primitives.
Abstract: The article discusses system-level issues and agent programming requirements that arise in the design of mobile agent systems. The authors describe several mobile agent systems to illustrate different approaches designers have taken in addressing these challenges. The following areas are discussed: agent mobility, naming, security issues, privacy and integrity, authentication, authorization and access control, metering and charging mechanisms, programming primitives, agent communication and synchronization primitives, agent monitoring and control primitives, and fault tolerance primitives.
