In this paper, the authors study the routing security issues of MANETs, they propose an algorithm to detect malicious nodes based on intelligent water drops algorithm and examine "Routing modification attack" problem that can easily be exploited against the MANETs. They also propose a solution for this problem and examine security issues related to proactive routing protocols for MANETs. This could be achieved by adding some extensions to secure routing. These extensions include integrity which means that the message will not change along the route and authentication which means that the sender is the one who introduces himself. This protection is provided by a hash chain and authentication by digital signature which both added to all control massages.
