本文对中间人攻击和防范进行了一定的分析,并且针对量子密钥分配以BB84协议为例提出了中间人攻击,提出一些防范方法,如传统密码学的数字签名,实用的多途径发布验证信息。并且提出一种利用在传输中插入量子纠缠态粒子的量子鉴别监听的方案来发现中间人攻击的存在。
This paper analyzes some man-in-the-middle attacks and precautions and proposes a man-in-the-middle attack against the example of BB84 protocol. Some precautionary measures are put forward, such as digital signature of traditional cryptography and practical multi-path publishing verification information. And we propose a scheme to detect man-in-the-middle attacks by using the scheme of quantum identification interception in quantum entangled particles during transmission.
