Network and Trust Model for Dynamic Federation

Free registration required

Executive Summary

Most existing approaches to identity federation are based on static relationships. This leads to problems with scalability and deployment in real-time environment such as mobile networks. This paper introduces an underlying network and trust model for dynamic federation. The authors present a modified Dijkstra algorithm to calculate the trust value and apply a distributed reputation calculated based on the PageRank algorithm from Google to each entity in order to increase the attack resistance of the system.
