Mobile ad hoc networks (MANETs) are infrastructure-less, autonomous, and stand-alone wireless networks with dynamic topologies. Recently, cluster-based ad hoc networks which enhance the security and efficiency of ad hoc networks are being actively researched. And routing protocols for cluster-based ad hoc networks are also studied. However, there are few studies about secure routing protocols in cluster-based ad hoc networks. In this paper, we propose secure routing protocol for cluster-based ad hoc networks. We use Diffie-Hellman key agreement, HMAC, and digital signature to support integrity of routing messages, and finally can perform secure routing.
