摘　　要：在量子信道中,粒子在传输过程中通常会受到噪声的影响,提出基于自对偶量子低密度校验码的量子对话协议来抵抗噪声攻击,使用B构造法和U构造法相结合的方法来构造自对偶量子低密度奇偶校验矩阵。所提量子对话协议能够抵抗常见的外部攻击,且不存在信息泄露,提高了编码和译码的效率。从纠错的角度研究所提量子对话协议的安全性,安全分析表明,该协议具有足够的安全性,能够有效抵御常见的恶意攻击。In quantum channels,particles are usually affected by noise during transmission.A quantum dialogue protocol based on self-dual quantum low density parity check codes was proposed to resist noise attacks.A combination of B construction method and U construction method was used to construct a self-dual quantum low density parity check matrix.The proposed quantum dialogue protocol can resist common external attacks,and there was no information leakage,which improved the efficiency of encoding and decoding.The security of quantum dialogue protocol was studied from the perspective of error correction.Security analysis shows that the protocol has sufficient security and can effectively resist common malicious attacks.
