Abstract:
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. This analysis allows the formal description of the reasoning for OLSR entities to have a protective mistrust behavior when acting based on trust relations.
