Abstract

Cyberspace has become the most popular carrier of information exchange in every corner of our life, which is beneficial for our life in almost all aspects. With the continuous development of science and technology, especially the quantum computer, cyberspace security has become the most critical problem for the Internet in near future. In this paper, we focus on analyzing characteristics of the quantum cryptography and exploring of the advantages of it in the future Internet. It is worth noting that we analyze the quantum key distribution (QKD) protocol in the noise-free channel. Moreover, in order to simulate real situations in the future Internet, we also search the QKD protocol in the noisy channel. The results reflect the unconditional security of quantum cryptography theoretically, which is suitable for the Internet as ever-increasing challenges are inevitable in the future.

Highlights

With the popularization and rapid development of the Internet, human society has entered the information age
As stated previously, exploring quantum cryptographic protocols will be an essential part of cyberspace security issues for future Internet
Quantum cryptography stems from the concept of quantum money, which was proposed by Wiesner in 1969

Summary

Introduction

With the popularization and rapid development of the Internet, human society has entered the information age. In 1990s, the term “cyberspace” was used to represent many new ideas and phenomena in the Internet, networking, and digital communication [1] Nowadays, this term is used to describe the domain of the global technology environment by experts and researchers of technical strategy, security, government, military, and industry and enterprises. This suggests that in order to resist quantum computers, new cryptosystems that are not based on discrete logarithms problem or the large factor decomposition problem should be explored In this way can the information security of cyberspace be ensured in the future Internet. We concentrate on analyzing and exploring the quantum key distribution protocol target for cyberspace security for the future Internet.
