Verifying Hotspot Quality User Rating with Certified QoS Evidence

Wi-Fi networks and its users are increasing more and more. Unfortunately, the risk of using one Wi-Fi or another varies and there is no means of selecting the most trustworthy hotspot. There are different solutions like websites that provide a way for the users to rate the hotspot after they have used it. However, there is no means to verify whether the user rating is trustworthy or not. Our solution allows the users to rate the networks they have used and to check that their rating corresponds to the true network quality they have experienced by measuring and certifying Quality of Service (QoS) evidence such as delay, jitter and packet loss. We validate our solution by proving when this certification is irrefutable and when other means, such as further history-based trust management, are needed.
