Nowadays, peer-to-peer (P2P) streaming systems have become the most popular way to deliver multimedia content over the internet due to their low bandwidth requirement and high video streaming quality. However, P2P streaming systems are vulnerable to various attacks, especially pollution attacks, due to their distributed and dynamically changing infrastructure. In this paper, by exploring the un...

In this paper, we introduce a framework for providing incentives for honest participation in global-scale distributed trust management infrastructures. Our system can improve the quality of information supplied by these systems by reducing free-riding and encouraging honesty. Our approach is twofold: (1) we provide rewards for participants that advertise their experiences to others, and (2) imp...

The use of RFID technology in complex and distributed environments often leads to a multi-domain RFID system, in which trust establishment among entities from heterogeneous domains without past interaction or prior agreed policy, is a challenge. The current trust management mechanisms in the literature do not meet the specific requirements in multi-domain RFID systems. Therefore, this paper ana...

During their everyday decision making, humans consider the interplay between two types of trust: vertical trust and horizontal trust. Vertical trust captures the trust relationships that exist between individuals and institutions, while horizontal trust represents the trust that can be inferred from the observations and opinions of others. Although researchers are actively exploring both vertic...

Computational trust is a central paradigm in today’s Internet as our modern society is increasingly relying upon online transactions and social networks. This is indeed leading to the introduction of various trust management systems and associated trust models, which are customized according to their target applications. However, the heterogeneity of trust models prevents exploiting the trust k...

Mainly justified by the growing concern about vulnerabilities of IT systems, some new technologies are being integrated into computing devices, for realizing so-called Trusted Computing systems. However, they are raising questions about intrusive cyber-control over individual user activities and data, but also about consequences in cyber-war scenarios. The aim of this article is to confront Tru...
