Abstract

Critical information infrastructures contain specific nodes that provide security services; those are called security or trust centres. The goal of this paper is to find algorithms for enabling trust centres to become sustainable by sharing (superfluous) their security resources. The first algorithm indicates the number of segments the total distrusted infrastructure has to be split in to result in many smaller trusted groups. The second type of algorithms is meant to enable the autonomous trust valuation by the nodes. The third type of algorithm comprehends the creation of and the distribution of security assets to other resources.
