量子时代的网络安全挑战及其应对研究

The cyber security challenge in the quantum era and its countermeasures

量子信息技术的迅速发展对信息通信技术及网络安全将产生深远的影响。量子计算对传统密码学提出新的挑战,也为基于量子物理的新型量子密码技术的发展提供了契机。本文首先从密码学的历史演进出发,介绍从经典密码到量子密码的基本概念;然后对量子计算引发的安全问题、影响范围、紧迫性进行分析,并进一步探讨其应对措施和方案。

The rapid development of quantum information technology will have a profound impact on information and communication technology and cyber security. Quantum computing poses new challenges to traditional cryptography and also stimulates the development of quantum cryptography based on quantum physics. This paper begins with the historical evolution of cryptography and introduces the basic concepts from classical cryptography to quantum cryptography. Then it analyzes the quantum security problems and its urgency caused by quantum computing, and further explores its countermeasures and solutions.
