A Review on Key Management Schemes in MANET

Mobile Ad-hoc network is spontaneous and infrastructure less network, which consist of wireless mobilenodes. MANET is formed on-the-fly and also provides various operations like packet forwarding, routing, network management, communication, etc between mobile nodes. MANET is one of the types of wireless network, in which any mobile node can join the network and leave the network in dynamic period. Mobile ad-hoc network doesn’t having centralized infrastructure and due to its basic characteristics this network is very vulnerable to attack. There are lots of trust models and routingprotocol which are used in MANETs to achieve security. Different trust schemes are used to provide confidentiality, integrity and availability in mobile ad-hoc network to gain the secure environment. In this paper, we present the study on various kinds of key management schemes with their special features.
