Abstract
This paper describes dynamic routing with securityusing a cryptographic algorithm which can be used in multiple organization
system. The problem of security is the major issues for data communication over worldwide networks. The main objective of this paper is to
propose a dynamic routing with security considered using strongest algorithm, such as Blow fish algorithm. Blow fish algorithm provides the
strong security from the client to the server system. The dynamic routing avoids two consecutive packets on the same link and updates the
routing information from neighbors of the router in the network. The main aim of this paper is a provide strong security from many
organizations to a head of the organization, such as Banks, Colleges, Companies, Universities as they need a strong security for data
communication. So this paper main issue is to provide strongest security and less time for data transmission from the clients to a server
INTRODUCTION
Various security-enhanced measures have been described to
improve the security of data transmission over wired and wireless
networks. As the existing work on security-enhanced data
transmission includes the designs of cryptography algorithms and
system infrastructures and security-enhanced routing methods.
Their objectives is to defeat various threats over the Internet,
including eavesdropping, spoofing, virus ,worms, session hijacking,
etc . As Among many well-known designs for cryptography based
systems, the P Security (PSec) and the Secure Socket Layer (SSL)
are popularly supported and been implemented in many systems
and platforms. Although PSec and SSL do greatly improve the
security level for data transmission and they unavoidably
introduce substantial overheads [8], especially on gateway
performance. Data Encryption Standard (DES) /Advanced
Encryption Standard (AES) [11] are adopted for
encryption/decryption of data transmission in the net work
system IPSec [14] .Another alternative for security-enhanced data
transmission is to dynamically route packets between each source
and its destination so that the chance for system break-in, due to
successful interception of consecutive packets for a session, is
reduce. The main intention of security-enhanced routing is
different from the adopting of multiple paths between a source
and a destination to increase the throughput of data transmission.
The set of multiple paths between each source and destination is
determined in an online fashion, and extra control message
exchanging is needed, propose a secure stochastic routing
mechanism to improve routing security. The explored the trading
of the security level and the traffic dispersion. They propose data
traffic dispersion scheme to reduce the probability of
eavesdropped information along the used paths provided that the
set of data delivery paths is discovered in advance
PROPOSED SYSTEM
Dynamic routing algorithm that could be randomizes delivery
paths for data transmission over wired and wireless networks. The
objective of this work is to explore a strong security enhanced
dynamic routing based on cryptographic algorithm in existing
wired and wireless networks. We aim at the randomization of
delivery paths for data transmission to provide considerably small
path similarity (i.e., the number of common links between two
delivery paths) of two consecutive transmitted packets. The same link and updates the routing information from neighbors‘ of
the router in the network .Advantages Of Proposed System are:
• Our security enhanced in the multiple-autonomous
system using a dynamic routing with strong
cryptographic algorithm for data transmission.
• Overhead is a minimized, if any faults in the routing
path, we need not setups a new path and routing table
information, it provides automatically setup of path
itself and a strong security from client to server.
• It provides a strong security and fast data encryption
and decryption from the client to the destination in the
multiple autonomous systems.
• It is a taking a very less time for Bulk encryption of the
data processed in the cryptographic system.
dynamic routing provides to avoid two consecutive packets on the
Client-Server System
Client-server computing or networking is a distributed application
architecture that partitions tasks or workloads between service
providers (servers) and operate over service requesters, called
clients. Often clients and servers a computer network on separate
hardware. A server machine is a high-performance host that is
running one or more server programs which share its resources
with clients [20]. A client also shares any of its resources; Clients
therefore initiate communication sessions with servers which
await (listen to) incoming requests.This is client/server computing
described. To truly understand how much of the Internet
operates, including the Web, it is important to understand the
concept of client/server computing. The client/server model is a
form of distributed computing where one program (the client)
communicates with another program (the server) for the purpose
of exchanging information. A typical client/server interaction goes
like this:
• The user runs client software to create a query.
• The client connects to the server.
• The client sends the query to the server.
• The server analyzes the query.
• The server computes the results of the query.
• The server sends the results to the client.
• The client presents the results to the user.
• Repeat as necessary
CRYPTOGRAPHY SYSTEM
Cryptography is the science of encrypting and decrypting written
communication. It comes from the Greek word ―kryptos,
meaning hidden, and ―graphia, meaning writing. Cryptanalysis is
the process of trying to decrypt encrypted data without the key
[1]. A system that provides encryption and decryption is referred
to as a cryptosystem
Dynamic routing with Blow fish algorithm in the Multiple Organization system
Blow fish algorithm provides a strongest security from source to
destination with the fast data processed in the multiple
organization system. Now, days security is a more important for
data communications from client to server in any fields. The
security-enhanced dynamic routing algorithm based on Blow fish
algorithm widely supported in existing wired and wireless
networks.
The different organization system needs high security for data
transmission from one organization to other organizations system.
If security has not a strong in the any organization system ,any
one hackers the their important information to lose the
organization information ,so we need a strong security for data
communications between client and server in the organization
system ,so we have to choose a strong security and fast
encryption for data processing in the organization system, so we
are using a strong security algorithm for data communication
between source and destination, such as Blow fish algorithm is a
strength of key length more than DES algorithm. As shown in the
figure 8, it shows the dynamic routing with security using Blow
fish algorithm in the multiple organization system. In that figure
can be divided into three kinds of figures shows different ,Clients
Routers and Servers these are using for different organizations
system in different kinds of password are maintaining because any
one can hackers their important information, so they need
strongest security for data communication between clients and
server. Now day‘s security is a more important for data
transmission in the autonomous system. As shown in the figure
(A.1), it consists of number of clients are connected to server via
router.
