摘要

随着量子计算机的不断发展，卫星互联网的安全性面临严峻挑战。首先，介绍卫星互联网和后量子密码的基本概念，深入分析卫星互联网在量子计算威胁下的安全需求。然后，通过对国内外后量子密码研究现状的综述，探讨基于格、编码、哈希函数和多变量多项式等后量子密码技术路线的特点及其在卫星互联网中的应用潜力。并通过比较分析，提出适合卫星互联网的后量子安全架构，为应对未来可能的量子计算威胁奠定基础。最后，探讨卫星互联网在量子计算时代所面临的主要安全问题和挑战，并提出相应的应对策略。

Abstract

With the ongoing development of quantum computers

the security of satellite Internet faces significant challenges. This paper first introduced the basic concepts of satellite Internet and post-quantum cryptography

thoroughly analyzed the security needs of satellite Internet under the threat of quantum computing. By reviewed the current research status of post-quantum cryptography both domestically and internationally

this paper explored the characteristics and application potential of various post-quantum cryptographic approaches

included lattice-based

code-based

hash-based

and multivariate-based techniques. Through comparative analysis

a post-quantum security architecture suitable for satellite Internet was proposed

laid the groundwork for addressing future quantum computing threats. Finally

the paper discussed the main security issues and challenges that satellite Internet may face in the quantum computing era and proposed corresponding countermeasures.
