Key Management in Hierarchical MANET Using Kerberos

International Journal of Distributed and Parallel systems, 2012

Mobile Ad-hoc network is spontaneous and infrastructure less network, which consist of wireless mobile nodes. 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 routing protocol 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.

Mobile ad hoc networks (MANETs) can be defined as a collection of large number of mobile nodes that form temporary network without aid of any existing network infrastructure or central access point. Due to the nature of MANETs to design and maintaining security is challenging task for researcher in an open and distributed communication environment. This paper we proposed security architecture for MANET grid and optimal key management by combines symmetric key technique and elliptic curve public key technique. The proposed architecture and optimal key management eliminates threats including the man-in-the-middle attack and the Black hole attack can be effectively eliminated under the proposed scheme. The core advantages of the proposed scheme include strong security, scalability, fault-tolerance, accessibility, and efficiency.

Abstract- Mobile ad hoc networks (MANETs) can be defined as a collection of large number of mobile nodes that form temporary network without aid of any existing network infrastructure or central access point. Due to the nature of MANETs to design and maintaining security is challenging task for researcher in an open and distributed communication environment. This paper we proposed security architecture for MANET grid and optimal key management by combines symmetric key technique and elliptic curve public key technique. The proposed architecture and optimal key management eliminates threats including the man-in-the-middle attack and the Black hole attack can be effectively eliminated under the proposed scheme. The core advantages of the proposed scheme include strong security, scalability, fault-tolerance, accessibility, and efficiency.

MANET does not have pre-existing fixed structure. Mobile nodes send packets to the destination nodes directly or via the intermediate nodes. Nodes exchange packets with each other to allow the message to pass among both ends step by step. These packets are outside the wireless transmission range. It is for potential security concern because intermediate nodes cannot be trusted. With such feature ad-hoc networks are least attacked which influences performance of the network with its reliability. Secure communication in MANET is to be claimed by the reliability parameter of the key management strategy, which is capable for securing contents among the nodes. This survey presents the conceptual view for various key management techniques with their special features.

GROUP KEY MANAGEMENT IN WIRELESS AD-HOC AND SENSOR NETWORKS Mohammed A. Moharrum Old Dominion University, 2006 Director: Dr. Ravi Mukkamala A growing number o f secure group applications in both civilian and military domains is being deployed in WAHNs. A Wireless Ad-hoc Network (WAHN) is a collection o f autonomous nodes or terminals that communicate with each other by forming a multi-hop radio network and maintaining connectivity in a decentralized manner. A Mobile Ad-hoc Network (MANET) is a special type o f WAHN with mobile users. MANET nodes have limited communication, computational capabilities, and power. Wireless Sensor Networks (WSNs) are sensor networks with massive numbers o f small, inexpensive devices pervasive throughout electrical and mechanical systems and ubiquitous throughout the environment that monitor and control most aspects o f our physical world. In a WAHNs and WSNs with un-trusted nodes, nodes may falsify information, collude to disclose system keys, or even ...

In this paper we present a key management protocol for wireless ad hoc multi-hop networks. Two objectives were crucial in our design: (1) distributed trust to ensure robustness, and (2) strong authentication to prevent the battery drain attack. We achieve distributed trust by presenting a hierarchical and distributed public key infrastructure for ad hoc networks. Our PKI has been designed to map onto hierarchical ad hoc networks, while maintaining global connectivity and flexibility. If a misbehavior detection scheme is present on the network, then the security of our PKI can be improved through collaboration with this scheme. Next to this PKI we propose a mechanism to securely establish and maintain link keys between the different nodes in the network.

Mobile ad-hoc networks (MANETS) are infrastructure less networks and the topology of this network is always changing. The nodes can enter and leave the network at any time. These networks require a high security in communication, as its application demands so. Effective key management is the only technique, which can implement to secure the nodes in communication. In adhocnetworks there is no central controller or router such as in wired network. This will make this network more vulnerable to attack. The intruders can easily enter the net-work and can manipulate the contents easily. Traditional key management schemes will not fit for this type of networks. This article, discuss various key management schemes based on routing protocols in mobile ad-hoc network (MANET). It also analyses them in terms of the security and applicability.
