Analysis of the implicit trust within the OLSR protocol

Abstract

Trust is an interesting criterion for analyzing and comparing network protocols. The goal of this paper is to explicit the different types of trust relations between entities which exchange routing information and establish a routing infra-structure based on the OLSR protocol. One such entity assumes the other entities will behave in a particular way and the relations coming from this trust behavior are expressed in this paper using a formal language. This approach highlights the process of trust construction in OLSR and allows the analysis of trust requirements for this protocol, as well as the expression of attacks related to the betrayal of trust relations. Besides, this analysis allows the description of indicators for OLSR entities to have a protective mistrust behavior when effectively acting based on trust relations. © 2007 International Federation for Information Processing.
