In this paper, the authors concerned with security in Mobile Ad hoc NETworks (MANETs). MANETs have unique characteristics and constraints that make traditional approaches to security inadequate. In particular, it is not appropriate to assume preexisting shared secret keys or authentication among members. The lack of an infrastructure exacerbates the situation. Therefore the issues of authentication, key distribution, and intrusion detection require different methods, which are discussed in this paper. Traditional authentication, key distribution, and intrusion detection methods are often too inefficient to be used in resource-constrained devices in MANETs.
