基于压缩态的量子密钥分配技术分析

Key Distribution Technology Based on Squeezed State of Quantum

信息安全在信息社会扮演着越来越重要的作用,研究密码学是保障信息安全的重要课题。本论文提出了一个基于压缩态非高斯调制的四进制量子密钥分配协议,通过对误码率的描述,分析了协议在Eve采用最佳攻击一纠缠克隆攻击时的安全性。

The information security plays a more and more important role in the information society.Study of cryptography is an important subject in information security.This paper presents a system based on four quantum key distribution protocol in the compression state of non-Gauss modulation.Based on the description of the error rate,we give an analysis of security protocols using the best attack-entangled cloning attacks at Eve.
