A light weight security scheme for HWMP protocol using Elliptic Curve technique
Jalel Ben‐Othman, Yesica Imelda Saavedra Benítez · 2011
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 original HWMP.
