Existing Global Navigation Satellite Systems offer no authentication to the open service signals and so stand-alone receivers are vulnerable to meaconing and spoofing attacks. These attacks interfere with the integrity and authenticity of satellite signals: they can delay signals, or re-broadcast signals. Positioning is thus compromised and location-based services are at risk.This paper describes a solution to mitigate this risk. It is a trusted third-party Localisation Assurance service that informs location-based services providers up to which level a location claimed by client can be trusted. It runs several tests over the localisation data of client receivers and certifies the level of assurance of locations. An assurance level expresses the amount of trust the third-party has that a receiver's location is calculated from integral and authentic satellite signals. [less ▲]

Current major P2P systems focus on PCs and do not provide services for the mobile environment. Compared to traditional P2P, characteristics of Mobile P2P include unreliable connections, limited bandwidth and constraints of mobile devices. In addition, nomadic users demand applications and services that are context-aware, personalised, secure, and trustworthy. Recommender systems are one of these applications. In this paper, we aim at building a mobile P2P recommender system which dramatically reduces wireless traffic between peers, brings trustworthiness (each peer can choose to rely on opinions of peers whom he trusts), and ffers unobtrusiveness (the target system is mainly autonomous and requires a minimum user intervention). Our solution is based on multi-agent systems and is illustrated on a slow-food restaurant recommender system. © 2012 Springer-Verlag. [less ▲]

The last few years have consolidated our understanding that security and trust are a socio-technical matter. Hence a call for researchers from different disciplines, such as sociology, psychology and informatics, to construct a holistic vision of security and trust. STAST, the workshop on Socio-Technical Aspects in Security and Trust, is an international event to support such interdisciplinary research. It reaches its second edition in 2012. The first took place at the University of Milano (Milan, Italy), hosted by the International Conference on Network and System Security (NSS). The second edition was held at Harvard University (Cambridge, MA, USA), hosted by the Computer Security Foundation Symposium (CSF) — this volume gathers its post-proceedings. [less ▲]

Chapter 8 of this book has explained how computational trust and reputation can be used to select the trustworthy pieces of software among the plethora of pieces of software emerging from this dynamic self-organising software world as envisioned in this book. This chapter goes beyond mere initial static selection of pieces of software because over time the situation changes and previously trustworthy configuration of pieces of software may become untrustworthy. In this chapter, an approach for adaptive trust management, meaning that the trust algorithms adapt automatically themselves depending on the context, is explained and examplified in the domain of context-aware authentication applications.

We introduce and comment on the concept of contextual pseudo identity. A contextual pseudo identity is a soft identity token that is built from both a user's biometric and the context. When it comes to ubiquitous authentication, a contextual pseudo identity promises better security than that o ered by traditional biometrics-based identity tokens: the use of context improves the tokens' disposability and renewability, which are two essential properties in the protection of a user's real identity. Our algorithm for generating contextual pseudo identities extends a Fuzzy Embedder so that it accepts both biometric and context dependent input. We prove that our way of processing the context preserves the security and reliability properties of the Fuzzy Embedder used in our extension. An example shows how a user can utilize contextual pseudo identity to authenticate to and access ubiquitous services. [less ▲]
