STEGO- HUNTER: ATTACKING LSB BASED IMAGE STEGANOGRAPHIC TECHNIQUE
ABSTRACT
Steganography is the process of hiding secret information in a cover image. Our aim is to test a set of images for statistical artifacts due to message embedding in color images using LSB insertion method and to find out, which images out of them are likely to be stego. In a natural uncompressed image (i.e. 24bit BMP) each image is represented by three color channels (Red, Green and Blue), each of ....etc

ABSTRACT
“All input is evil until proven otherwise!”so security technology come into play.With the rapid growth of interest in the Internet, network security has become a major concern to companies throughout the world. The fact that the information and tools needed to penetrate the security of corporate networks are widely available has increased that concern.
Because of this increased focus on network security, network administrators ....etc

An Enhanced Pretty Good Privacy (EPGP) System With Mutual Non-Repudiation
Enhanced Pretty Good Privacy (EPGP) is a new cryptosystem based on Pretty Good Privacy (PGP), used for the purpose of secure e-mail message communication over an open network. The idea of EPGP, introduced in this paper, addresses PGP's main drawback of incomplete non-repudiation service, and therefore, attempts to increase the degree of security and efficiency of e-mail message communication.

Computer Security Pretty Good Privacy




Pretty Good Privacy

The success of our information economy depends, in large part, on
the ability to protect information as it flows. This relies on the
power of cryptography. RSA provides extremely strong encryption,
but is not particularly easy to use.
Phil Zimmermann had the goal of providing strong encryption for
the masses, in the form of an encryption system for email that is:
extremely str ....etc

A Seminar Report On Public Key Infrastructure

Abstract
Public Key Infrastructure is a system for supporting digital signatures and document encryption for an organization. It is fast becoming essential for an effective secure commerce and to fulfill general security and authentication requirements over non-secure networks (like the Net). The banking services are the most popular usage of this technology, which is quickly spreading over all the applications that need security to be fully operational.
The objective of ....etc
