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

Increasing the Efficiency of Ideal Solar Cells by Photon Induced Transitions
at Intermediate Levels

Antonio Luque and Antonio Martı´
Instituto de Energı´a Solar, Universidad Politécnica de Madrid, 28040 Madrid, Spain
(Received 7 February 1997)


Recent attempts have been made to increase the efficiency of solar cells by introducing an impurity
level in the semiconductor band gap. We present an analysis of such a structure under ideal conditions.
We prove that its efficiency can exceed not only the S ....etc

Hello, Iam yashwanth agrawal. Studying my b.tech second year. i want to do a project on secret bell. So i need to know the circuit diagram of it and a clear description of how thee circuit works and the wa it can be used in real time application.I currently am aware of what exactly is secret bell about and i have no idea of which digital ic to be used and all. I need to know from the root of it. So i hope that i will be answered for my questions very soon. And i will be very thankful if you can suggest me some intersting mini project, but the ....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

abstract
 Here secret data is embedded within skin region of image that will provide an excellent secure location for data hiding. For this skin tone detection is performed using HSV (Hue, Saturation and Value) color space. Additionally secret data embedding is performed using frequency domain approach - DWT (Discrete Wavelet Transform), DWT outperforms than DCT (Discrete Cosine Tr ....etc

Abstract:-
Authenticity is one of the key aspects of computer security. As a cryptographic technique that guarantees information authenticity, secret sharing has been an active research field for many years. With the efforts of pioneering researchers, secret sharing has reached the level of practical use in today's Internet-based applications, which is designed to protect a secret piece of information among a group of users in such a way that only certain subsets of users can jointly reconstruct the secr ....etc

In paper based financial messaging system, the messages are sent in defined formats duly signed by the authorized signatories. Paperless initiative and changes in the business practices have changed the authorization process. In electronic messaging, the messages are created, authenticated electronically and sent through electronic medium. Present technology facilitates data transmission with security integrity duly taking care of confidentiality and nonrepudiation of messages. Encryption and digital signature play a vital role in providing suc ....etc
