The document discusses the use of the MD5 algorithm for securing voice and video traffic over VPNs through data integrity measures. It describes the methodology for implementing MD5 with IPSec to ensure data is not modified during transmission, highlighting features like one-way function and checksum generation. The conclusion emphasizes the effectiveness of this approach in reducing network congestion and maintaining the integrity of communications.

IV. CONCLUSION
It mitigates the affect of packet delay
variation and packet end to end delay. It reduces
encapsulation time by using firewall. It provides data
integrity over the internet by using algorithm that is
Message Digest. If once the message is made then it
can’t be change. It is difficult to come back at the
original message. It provides security for voice and
video traffic over internet through established
firewall between two ends and use MD5 with IPSec
to provide data integrity. It provides better solution to
the remove the congestion in the network through
firewall.
V. ACKNOWLEDGMENT
I am very thankful to my Dissertation
mentor and my friends who guided me time to time
in developing my research related work. They left no
stone unturned to help me. Because of their kind
support and a very good knowledge of the subject, it
becomes possible to complete my research. And
finally God and my parents, due to them I am able to
stand at this stage in all respects. Thanks to all of
you.

MD5 generates a unique value of 128-bit cryptographic message digest which are derived from input stream. This value is highly reliable and flexible that can be used to verify the data integrity of files content. If a single bit value in the file is modified, the MD5 checksum for the file changes. Keywords- data integrity, checksum, MD5, firewall, VPN, Tunneling. I. INTRODUCTION MD5 is the extended version of MD4. The MD5 digest is used for data integrity in software systems. MD5 is used for storing secure information and transmitting data from source to destination, i.e. password and user name. Every user wants to gain access for some resources with entering the password. This algorithm is non reversible. It is hard to break because it is one way function. It can’t restore to original message. Process time increases with message size increases to generate digest value. Using MD5 with IPSec as tunnel, we can provide the security over internet. MD5 is more secure as compared to other algorithms. This scenario consists of two nodes which are at source and destination and 2 routers are placed between them. IPSec tunnel used to protect the data by using MD5. It provides data integrity that the make sure data which are coming from source didn’t modify. For end to end communication, we use IPSec modes. The two modes of IPSec are Transport Mode and Tunnel Mode. Transport mode is used to protect the protocol and Tunnel mode is used to protect the whole IP datagram. IPSec used to protects the voice and video traffic by tunnel. Here router works as firewall. The protocol used for voice is G.722 and for video is H.263. HMAC-MD5 used for data integrity mechanism. II. BASIC ALGORITHIM 5 basic steps are involved in MD5 algorithm: 1. Append padding bits 2. Append Length 3. Initialize MD Buffer 4. Process Message in 16-Word Blocks 5. Output III. METHODOLOGY Step by step methodology is used for providing security in VPN for voice and video traffic. There is a flowchart which describes the scenario of research process. Flowchart consists various kind of boxes, arrows which describes the flow of information. RESEARCH DESIGN:
