Certification and Authentication Services for Securing MANET Routing Protocols
Ricardo Puttini, Ludovic Mé, Rafael T. de Sousa · 2003
Abstract: In this paper, we describe a new authentication service for securing mobile ad hoc network (MANET) routing protocols. A MANET authentication extension (MAE) is appended to each routing protocol message. Our design includes a self-organized certification service, adapted from [6] with the following improvements: appropriated initialization, correcting vulnerabilities in the original design; local certificate management; and support to multiple Certification Authorities. Our design is policy-configurable in the sense that certification and authentication services may be adjusted according to specific security requirements. We discuss the use of MAE and certification service for securing DSR, AODV, OLSR and TBRPF MANET routing protocols. We have implemented the MAE securing OLSR and we evaluate computational and network requirements for this case. Key Words: MANET, routing protocol security,
