Resilient Trust Management for Web Service Integration

Overview

In a distributed web service integration environment, the selection of web services should be based on their reputation and Quality-of-Service (QoS). Various trust models for web services have been proposed to evaluate the reputation of web services/service providers. This paper presents an attack resilient distributed trust management system in a web service management environment. The proposed attack resilient trust model uses two vectors to capture the behavior and the trustworthiness of a web service/service provider based on their analysis on the possible attacks against the trust models. They also present a set of experiments that show the effectiveness of their trust model in detecting malicious behavior of service providers.
