Abstract:
Ad Hoc networks are an ideal way to form interactions between mobile wireless nodes of
emergency services from different domains (i.e. organizations or countries). However,
due to the frequent topological and membership changes it is difficult to form trust
relationships in an Ad Hoc environment. The existing approaches for building security
relationships in Ad Hoc networks are either computationally intensive or require
extensive initial coordination/pre-configuration of participating nodes. To address these
shortcomings this thesis proposes the use of a flexible trust negotiation approach
involving confidential and progressive exchange of digital certificates. This certificate
exchange is governed by the local policies of the two participating nodes. A local policy
on the service providing node maps the attributes from the certificates received into
services it can provide to the remote node. A two-tier key formation scheme is also
proposed to ensure the confidentiality of the trust negotiation process and to secure the
communication paths.
