Quantum Cryptography for the Future Internet and the Security Analysis

Abstract EN

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.
