Abstract—In this paper we present a mechanism for securing the OLSR protocol. This mechanism is implemented as an extension to the OLSR source code provided from UniK (www.olsr.org), and can be downloaded freely from the Internet. The proposed and implemented mechanism is based on signing each OLSR control packet with a digital signature for authenticating this message. Also, the mechanism provides a timestamp exchange process. The timestamps are used to prevent replay attacks on the routing protocol. This security mechanism does not need synchronized time.
