Quantum cryptography is an effort to allow two users of a common communication channel to create a body of shared and secret information. This information, which generally takes the form of a random string of bits, can then be used as a conventional secret key for secure communication. It is useful to assume that the communicating parties initially share a small amount of secret information, which is used up and then renewed in the exchange process, but even without this assumption exchanges are possible.

Abstract

While many protocols for sensor network security provide confidentiality for the content of messages, contextual information usually remains exposed. Such information can be critical to the mission of the sensor network, such as the location of a target object in a monitoring application, and it is often important to protect this information as well as message content. There have been several recent studies on providing location privacy in sensor networks. However, these existing approaches assume a weak adversary model where the ad ....etc

ABSTRACT


Many organizations are working hard to secure themselves from the
growing threats of message hacking through various trends in
cryptography.Yet the headlines are dominated with the latest news of
message passing disaster more frequently than any time before.This
document intends to review this problem and propose several possible
solutions.The cryptographic industry has been responding to these
threats with ever-quicker responses to the rapid onslaught of malicious
techniques,while corp ....etc

Abstract—While many protocols for sensor network security provide confidentiality for the content of messages, contextual information usually remains exposed. Such contextual information can be exploited by an adversary to derive sensitive information such as the locations of monitored objects and data sinks in the field. Attacks on these components can significantly undermine any network application. Existing techniques defend the leakage of location information from a limited adversary who can only observe network traffic in a small region. ....etc

Kerberos is security system that helps prevent people from stealing information that gets sent across the wires from one computer to another. Usually, these people are after your password. The name Kerberos comes from the mythological three-headed dog whose duty it was to guard the entrance to the underworld. The Kerberos security system, on the other hand, guards electronic transmissions that get sent across the Internet. It does this by scrambling the information -- encrypting it -- so that only the compu ....etc

Zero Knowledge Protocols and Proof Systems

Zero-knowledge protocols allow identification, key exchange and other basic cryptographic operations to be implemented without leaking any secret information during the conversation and with smaller computational requirements than using comparable public key protocols. Thus Zero-knowledge protocols seem very attractive especially in smart card and embedded applications. There is quite a lot written about zero-knowledge protocols in theory, but not so much practical down-to-earth material is availabl ....etc

Acoustic Cryptanalysis Attempts on CPU and Keyboard

ABSTRACT
Acoustic sound is a natural phenomenon which can be emitted from interactions among physical objects or materials with its specific acoustic signature in frequency, amplitude and signal pattern or spectra. The emission occurs when a small surface displacement of a material is produced due to a rapid release of energy in a material, or on its surface. Acoustic sound which has specific spectra signature could be a powerful tool to reveal important information from the object bein ....etc

ABSTRACT
TEMPEST and ECHELON are the method of spying in a
sophisticated manner; both are developed by National Security Agency
(NSA) for monitoring the people. These technologies are originally
developed for pure military espionage, but hackers use them now for
spying in to other peopleâ„¢s activities.
Tempest is the technology, which can reproduce what
you are seeing in your monitor, what you are typing in your keyboard
from a couple of kilometers away. It traces all electromagnetic

Quantum cryptography becomes a reality
According to reliable sources from NEC, Commercial quantum cryptography, a revolutionary system that can produce quantum keys at a speed of 100Kbit/s and then broadcast it up to 40 kilometres along the commercial fibre optic lines will be available in the markets by the second half of 2005. Speaking in line with Kazuo Nakamura, senior manager of NEC's quantum information technology group at the company's Fundamental and Environmental Research Laboratories, it ca ....etc
