On the other hand it helps us steer away from unacceptable risks and potential deceptions. While human intuition about trust often fails, it seems to provide us with guidance very quickly in m...

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, high video streaming quality, and flexibility. However, P2P streaming systems are vulnerable to various attacks, especially pollution attacks, due to their distributed and dynamically changing infrastructure. In this paper, by ex...

The dynamic nature of context can strongly affect trust management and service selection. In this paper, we present a context-based trust mana...

Security and trust management in Vehicular Adhoc NETworks (VANET) is a crucial research domain which is the scope of many researches and domains. Although, the majority of the proposed trust management systems for VANET are based on specific road infrastructure, which may not be present in all the roads. Therefore, road security should be managed by vehicles themselves. In this paper, we propos...
