摘要

提出一种基于单粒子的量子公钥加密协议。利用随机序列的映射关系对私钥实施量子操作，生成用于消息加密的量子公钥。根据量子不可克隆和密文不可分辨定理，引入新的量子源作为通信传输的载体，设计了易操作的加密编码和解密规则；采用分块的方法，优化了窃听检测方法，降低了对发送方存储能力的要求；结合一次一密的加密方案，保证了在量子通信信道中传送密钥和消息的安全性。基于纠缠态的量子加密算法和基于单粒子的量子公钥加密方案相比较，所提出的协议易于实现，具有良好的使用价值。分析表明，本协议是安全的。

Abstract

A quantum public-key encryption protocol based on single-photon was provided.Pseudo random sequence mapping to private keys to implement corresponding quantum operations and then obtaining quantum public-key to encode the plaintext was used.Employ the method of block classification to lower the requirement for storage capacity of the sender.A new quantum source as transmission carrier was introduced and simply encoding and decoding rules were designed based on the laws of quantum non-cloning and ciphertext indistinguishability.On the other hand

classical one-time pad technique is used to ensure the security of quantum key and plaintext in the transmission channel.At the same time

select different updating strategy of quantum public-key according to the results of error detection which can significantly reduce key consumption.Compared with the previous quantum public-key encryption based on entangled states and single-photon

there are no entangled states and decoyed particles are needed

so it is not only efficient to reduce the overhead of communication traffic between legitimate users

but also easier to carry out in practice.The analysis shows that the proposed scheme is secure.
