Today wired computer systems can be made secure to a high degree, but when it comes to wireless networks weak security is often used if any security measurements are taken at all. This affects the services running on wireless networks including MANET routing protocols.
In this chapter an extension to secure OLSR is presented. This extension only provides security extensions to OLSR and not the traffic being routed in the MANET. Also, the implemented solution only provides integrity and not confidentiality, although the solution is extendable and could include mechanisms to provide confidentiality.
As this thesis is not mainly focused on security, the concepts of encryption, key management and digital signatures will only be briefly presented. It is assumed that the reader is familiar with the concepts of confidentiality, integrity and availability.
