A Recent Survey on Key Management Schemes in MANET
Aziz Baayer, Enneya Nourdine, Elkoutbi Mohamed · 2008
An ad hoc mobile network (MANET), is a collection of wireless mobile hosts that form a temporary network without the aid of any centralized administration or support. In such a network, each mobile node operates not only as a host but also as a router, forwarding packets for other mobile nodes in the network that may be multiple hops away from each other. With those network Characteristics, security has become a primary concern for researchers to meet scientific challenges to market opportunities in term of confidentiality, authentication, integrity, availability, access control, and non-repudiation. In the same way and as a powerful tool in achieving security, the Key Management becomes a corner stone in MANET security by proposing an appropriate secure schema for handling cryptographic keying materials. The Key Management scope includes key generation, key distribution, and key maintenance. In this paper, we aim to evaluate and to present a recent overview on different research works on Key Management in MANETs.
