The Next Generation IT Security System

Spies, communication, and secret codes! Cryptography is the art of encrypting and decrypting messages. It has existed as long as people have distrusted each other and looked for the forms of secure communication. Cryptographic techniques have evolved over the centuries. The aim is always the same – the code-makers work to stay ahead of the code-breakers. Today’s most common encryption methods are threatened by the potential creation of the quantum computer. In other words, quantum cryptography promises more secure communication than any existing technique.

Introduction

Quantum cryptography is focused on the unique behavior of microscopic objects which enable users to securely develop secret keys. The work on quantum cryptography was begun by Stephen J. Wiesner in the late 1960’s. The first protocol for sending a private key using quantum techniques is published in 1984 by Bennett and Brassard. The development of quantum cryptography is based on “public-key
