摘要

随着量子计算技术的发展，量子公钥密码学逐渐成为现有经典公钥密码学的替代技术。本文通过 EPR 对和量子测量设计了一种量子陷阱门单向函数。在此基础上，提出了一种新的量子公钥密码系统，它具有前向安全性，可以抵御选择平文攻击和选择密文攻击。与现有的量子公钥密码系统相比，这种新的量子公钥密码系统可以在一个必要条件下自动检测到窃听行为，这在论文中也有详细介绍。

Quantum public-key crypto via EPR pairs

With the development of quantum computing technology, quantum public-key cryptography is gradually becoming an alternative to the existing classical public-key cryptography. This paper designs a quantum trapdoor one-way function via EPR pairs and quantum measurements. Based on this, a new quantum public-key cryptosystem is presented, which offers forward security, and can resist the chosen-plaintext attack and chosen-ciphertext attack. Compared with the existing quantum public-key cryptos, eavesdropping can be automatically detected in this new quantum public-key cryptosystem under a necessary condition, which is also detailed in the paper.
