The establishment of a Public Key Infrastructure (PKI) in Mobile Ad Hoc Networks (MANETs) is considered a difficult task because of the intrinsic characteristics of these networks. The absence of centralized services and the possible network partitions make traditional security solutions not straightforwardly applicable in MANETs. In this paper, we propose a publ ....etc

We investigate the newer generation of wireless networks in this seminars. Adhoc networks find there application in the field of military tactical communications and various other emergency situations. Before we can efficiently use this type of network it is essential for us to understand the various control problems associated with adhoc networks. These include the power control problem. This problem infringes itself into the various layers of the OSI reference model. It basically affects the networking by affecting the battery life of the sys ....etc

SECURE KEY EXCHANGE AND ENCRYPTION
FOR GROUP COMMUNICATION IN
WIRELESS ADHOC NETWORKS


ABSTRACT

Ad hoc wireless networks is primarily important, because the communication
signals are openly available as they propagate through air and are more susceptible to attacks ranging from passive eavesdropping to active interfering. The lack of any central coordination and shared wireless medium makes them more vulnerable to attacks than wired networks. Nodes act both as hosts and routers and are interconnect ....etc

Abstract
In mobile ad hoc networks, due to unreliable wireless
media, host mobility and lack of infrastructure, providing secure
communications is a big challenge in this unique network environment.
Usually cryptography techniques are used for secure
communications in wired and wireless networks. The asymmetric
cryptography is widely used because of its versatileness (authentication,
integrity, and confidentiality) and simplicity for key distribution.
However, this approach relies on a centralized framework
of public key infras ....etc

Ad hoc networks are a new wireless networking paradigm for mobile hosts. Unlike traditional mobile wireless networks, ad hoc networks do not rely on any fixed infrastructure. Instead, hosts rely on each other to keep the network connected.

The military tactical and other security-sensitive operations are still the main applications of ad hoc networks, although there is a trend to adopt ad hoc networks for commercial uses due to their unique properties. One main challenge in design of these networks is their vulnerability to security attacks ....etc

Abstract
Three-party authenticated key exchange protocol(3PAKE) is an important cryptographic technique for securecommunication which allows two parties to agree a new securesession key with the help of a trusted server. In this paper, weproposed a new three-party authenticated key exchange protocolwhich aims to achieve more efficiency with the same security levelof other existing 3PAKE protocols. Security analysis and formalverification using AVISPA tools show that the proposed protocolis secure against various known attacks. Comparin ....etc
