There is an increasing need for internetworking between telephone and computer networks. Applications such as Voice over IP (VoIP) and the deployment of the 3rd Generation mobile telephony networks, make this integration a necessity. The Signaling Transport (SIGTRAN) working group of the Internet Engineering Task Force (IETF) is the one in charge of the design of the standards needed to make this internetworking possible. The primary purpose of this working group is addressing the transport of packet-based Public Switched Telephone Networks (PS ....etc

TCP Stream Re-assembly and Web-based GUI for Sachet IDS


Sachet is a Network based Intrusion Detection System developed at IIT Kanpur. It monitors the network traffic to detect any unwanted attempts to compromise the security of the network by malicious users. Recently an Intrusion Prevention functionality was also added to it. IPS monitors network traffic inline and prevent intrusions by dropping the malicious packets before they reach the actual host. In this thesis, we are adding two functionalities needed to enhance the utility o ....etc

Design and Implementation of RC4 stream for WI-FI security

In Cryptography the main feature is to work out with problems, which associated with secrecy, authentication and integrity. In order to handle all the cryptographic problems many kinds of cryptographic algorithms have been invented. The complexity of these problems made several categories of cryptographic algorithms. A much known is the RC4 stream cipher. The project deals with the design of RC4 stream cipher for wireless LAN security.

Block Ciphers - Analysis, Design and Applications




Abstract
In this thesis we study cryptanalysis, applications and design of secret key
block ciphers. In particular, the important class of Feistel ciphers is studied,
which has a number of rounds, where in each round one applies a cryptographically
weak function.

Applications
The main application of block ciphers is that of encryption. We study the
available modes of operat ....etc

CORE BANKING/ONLINE BANKING

The Online Banking is an application that has been developed for a well-established regional bank operating primarily in south India. The bank has several branches in key cities and towns in the north. In the world of this competitive environment and technological development, the bank has been totally computerized in the last 3 years, and to increase its customer base has started planning, for a concept called as e-banking; with this concept the bank wants to move very nearer to the customers and inc ....etc

Stream Processor

For many signal processing applications programmability and efficiency is desired. With current technology either programmability or efficiency is achievable, not both. Conventionally ASIC's are being used where highly efficient systems are desired. The problem with ASIC is that once programmed it cannot be enhanced or changed, we have to get a new ASIC for each modification. Other option is microprocessor based or dsp based applications. These can provide either programmability or ....etc

Abstract
Encryption algorithms can be used to help secure wireless communications, but securing data also consumes resources. The goal of this research is to provide users or system developers of personal digital assistants and applications with the associated time and energy costs of using specific encryption algorithms. Four block ciphers (RC2, Blowfish, XTEA, and AES) were considered. The experiments included encryption and decryption tasks with different cipher and file size combinations. The resource impact of the block ciphers w ....etc

Stream Ciphers
• Generate a pseudo-random key stream &
xor to the plaintext.
• Key: The seed of the PRNG
• Traditional PRNGs (e.g. those used for simulations) are not secure.
E.g., the linear congruential generator:
Xi = a Xi-1 + b mod m
for some fixed a, b, m.
It passes the randomness tests, but it is predictible.
Linear Feedback Shift Registers
Feedback shift register:
(“register”, “feedback”, “shift”)
LFSR: Feedback fnc. is linear over Z2 (i.e., an xor):
Very compact & effici ....etc
