摘要
由于量子的特殊特性,量子加密的实现存在许多困难,因此量子密码学中量子加密协议很少。分析了实现量子加密的几个障碍:量子态的不确定性、量子比特传输的噪声和错误等,并且克服这些障碍提出了量子密码的新分支——基于单量子态的量子加密协议。本量子加密协议利用传统密码学、纠错编码和量子力学原理相结合实现保密信息传递,同时分析了量子加密协议的安全性和其他特点。
Quantum encryption is difficult to realize because of quantum’s particular characteristics.There are few quantum encryption protocols.The paper analyses the barriers of quantum encryption that include the uncertainness of quantum and the noise and error of quantum transmission,and hurdles the barriers to bring out a new quantum encryption protocol which is a new offset of quantum cryptography.The protocol hangs together error correcting code,traditional cipher and quantum mechanics to transfer private message.At the same time,the paper analyses its security and other characteristics.
