Abstract

This paper proposes an efficient approach of secure clustering in distributed sensor networks. The clusters or groups in the network are formed based on offline rank assignment and predistribution of secret keys. Our approach uses the concept of weakly connected dominating set (WCDS) to reduce the number of cluster-heads in the network. The formation of clusters in the network is secured as the secret keys are distributed and used in an efficient way to resist the inclusion of any hostile entity in the clusters. Along with the desc ....etc

The project implements the fundamental establishment of group key through distributed and collaborative approach for a dynamic peer group. The main function of the project is to provide secured communication through key authentication process. Three Interval Based Re-Keying algorithms are used to eliminate the individual re-keying approach in which re-computation of the key is performed after each joining and leaving of the member. The three interval based re-keying algorithms are 1. Rebuild Algorithm 2. Batch Algorithm 3. Queue-Batch Algorithm ....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”
Wireless broadcast is an effective approach to disseminate data to a number of users. To provide secure access to data in wireless broadcast services, symmetric key-based encryption is used to ensure that only users who own the valid keys can decrypt the data. Regarding various subscriptions, an efficient key management to distribute and change keys is in great demand for access control in broadcast services. In this paper, we propose an efficient k ....etc

Dynamic Balanced Key Tree Management for Secure Multicast Communications - IEEE TRANSACTIONS ON COMPUTERS, VOL. 56, NO. 5, – java

Abstract—
A secure multicast communication is important for applications such as pay-per-view and secure videoconferencing. A key
tree approach has been proposed by other authors to distribute the multicast group key in such a way that the rekeying cost scales with
the logarithm of the group size for a join or depart request. The efficiency of this key tree approach critically depends on whether the ....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

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
