SUMMARYThe IEEE P802.11s/D4.0 standard is not considered secure for the routing protocol. In this paper, we propose IBC‐HWMP, a secure Hybrid Wireless Mesh Protocol (HWMP) using identity‐based cryptography (IBC). The reason we use IBC is that it does not need to verify the authenticity of public keys. We have implemented the IBC mechanism to secure control messages in HWMP, namely path request and path reply. Our aim is to focus on secure data exchange in mutable fields. Through extensive ns‐3 simulations, results show that the overhead introduced by IBC‐HWMP is not significant compared with the classical HWMP and that, at the same time, we improve the security.

In this paper, we propose a security mechanisms for the Hybrid-Wireless-Mesh Protocol (HWMP). Our mechanisms is based on the Identity Based Crytography (IBC). The motivation behind using IBC is that it eliminates the need to verify the authenticity of public keys. We have implemented the IBC technique to secure control message in HWMP, namely RREQ (Path Request) and RREP (Path Reply). In these Control messages, we are interested only by mutable (i.e. fields that an changing during control packet exchange). Through simulation experiments, we have evaluted the performance of our IBC-HWMP in terms of delay and control overhead. +Simulation results show that the IBC-HWMP does not induce a long overhead compared to the orignal HWMP protocol.

In this paper we have implemented the ECDSA (Elliptic Curve Digital Signature Algorithm) technique to provide security in HWMP (Hybrid Wireless Mesh Protocol). The motivation behind the use of ECDSA is that it is integrated into the IEEE P802.11s/D4.0 standard. We have used the ECDSA technique to secure control message in HWMP, namely PREQ (Path Request) and PREP (Path Reply). In these Control messages, we are interested only by mutable fields (i.e. fields that change during control packet exchange). Simulation results show that the ECDSA-HWMP does not too much a long overhead compared to the orignal HWMP.A. key word ECDSA, HWMP, Security, Routing Protocols, Mesh.
