Designing cost-efficient, secure network protocols

for Wireless Sensor Networks (WSNs).

Reduces the number of transmissions needed for

rekeying.

VEBEK is a secure communication framework where

sensed data is encoded using the RC4 encryption

mechanism.

Abstract Abstract

Existing SystemExisting System

There are two fundamental key management schemes for WSNs: Static and Dynamic.

oIn static key management schemes, key management functions are handled statically.

oDynamic key management schemes perform keying functions either periodically or on demand as needed by the network.

DisadvantagesDisadvantages

oCommunication cost is expensive in a sensor’s energy consumption.

oMessage transmission cost for rekeying is expensive in a WSN deployment

Proposed SystemProposed System

o An energy-efficient VEBEK scheme for WSNs will significantly reduces the number of transmissions needed for rekeying to avoid stale keys.

o VEBEK uses RC4 encryption mechanism.

o VEBEK is able to efficiently detect and filter false data injected into the network by malicious outsiders.

AdvantagesAdvantages

In comparison with other key management schemes

VEBEK has the following benefits:

Saves more energy and is less chatty.

More resilient to certain attacks.

Easy adoption of different key-based encryption or

hashing schemes

Module DescriptionModule Description

Sender:-Sender module deals with sender operations and

allows sender to transmit data to the receiver. Receiver:-Receiving Module will deals with the receiving

operations

Requirements Requirements

Software requirements IDE : Visual Studio

2008

Programming Language : C#.NET

Hardware Requirements Processor : Pentium IV Hard disk : 160 GB Ram : 1GB

ConclusionConclusion

o Communication is very costly for WSNs.

o Independent of the goal of saving energy, it may be very important to minimize the exchange of messages.

o VEBEK reduces the communication cost for wireless networks.

o VEBEK provides feasibility and optimal performance than others while providing support for communication error handling.
