This paper presents a lightweight probabilistic path authentication scheme for Mobile Ad hoc NETworks (MANETs) based upon a new cryptographic primitive composite MAC. The proposed path-authentication scheme allows them to reliably identify nodes on a route over which a sequence of packets traverses. This path-authentication scheme is robust against selfish or malicious nodes that do not follow the scheme. Furthermore, it allows them to detect, and up to a certain accuracy pinpoint, any misbehaving node that deviates from the correct forwarding behavior. In the authors' scheme, composite MAC can have any length starting from one bit. This flexibility allows the proposed scheme to strike various trade-offs depending on the constraints imposed by the MANET and the desired security properties.
