Introduction

This system is helpful in transmitting data from

source to destination with high security using

cryptography algorithms and security enhanced

routing methods that restricts loss of

information

ABSTRACT

y Security has become one of the major issues for datacommunication over wired and wireless networks.

Different from the past work on the designs ofcryptography algorithms and system infrastructures,we will propose a security enhanced dynamic routingalgorithm that could randomize delivery paths for data

transmission.

WHAT IS DYNAMIC ROUTING?y Dynamic routing enables network devices to obtain

topology information, routes and IP addresses fromother routers automatically.

WHAT IS THE PURPOSE OF DYNAMIC ROUTING ?

y

It allowed devices to dynamically learn networkinformation and reroute traffic around failed network.

y Interior gateway protocols such as RIP and OSPFautomatically discovered the addresses and states of

different devices on the network and determined the

WHAT IS SECURITY?y Security is the protection of a person, property or

organization from an attack. The types of protection

include prevention ,response and pre-emptive attacks.

HOW SECURITY PLAY A KEY ROLE IN NOW A DAYS?

Security solutions such as firewalls and VPNS, protectnetwork resources against attacks, intrusions ,andmalicious activity.

ALGORITHMS FOR DYNAMIC ROUTING

y

It is based on distributed routing information widelysupported in existing networks. In general routingprotocols over network could be classified roughly intwo parts .

y 1.distance vector algorithms

y Example: RIP and DSDV

y 2.link state algorithm

y Example :OSPF

ALGORITHMS FOR PROVIDING

SECURITY

y Security enhanced dynamic routing algorithm

y It is a distance vector based algorithm for dynamicrouting to improve the security of data transmission.

Existing System

y Existing work on security-enhanced data transmissionincludes the designs of cryptography algorithms andsystem infrastructures and Security enhanced routingmethods.

y IPSec and SSL do greatly improve the security level fordata transmission, they unavoidably introducesubstantial overheads, especially on gateway/hostperformance and effective network

Limitations of Existing System

IP sec VPNS

do not support a standard method ofexchanging route information over a encryptedtunnels.

Extra control messages needed.

Data transmission overhead.

Proposed System

y We will propose a security enhanced dynamic routingalgorithm to provide security enhanced data delivery

without introducing any extra contol messages.y It is based on DDRA.It consists of two parts

yA randomisation process for packet delivery

y Maintenance of the extended routing table

Advantages of proposed system

y Random delivery paths for data transmission

y

Easy to implement and Compatible with popularrouting protocols

y No extra control messages

yAdministrator has less work maintaining the

configuration when adding or deleting networks.y Protocols automatically react to the topology changes

y Configuration is less error phone

y More scalable

NETWORKMODULE:Client-server computing or networking is a distributedapplication architecture that partitions tasks orworkloads between service providers (servers) and

service requesters, called clientsDYNAMICROUTING:

To propose a distance-vector based algorithm fordynamic routing to improve the security of data

transmission.RANDOMIZATION PROCESS:

The delivery of a packet with the destination at anode.

The traffic is too generated based on changeable-bit-rate applications such as file transfer overTransmission

Control Protocol (TCP).
