【摘要】：提出在一个源量子节点与M个目的量子节点组成的网络中抗量子特洛伊木马攻击的多播通信协议,源量子节点构建2n+δ个EPR纠缠对,并用发送序列标记;在发送序列中随机选取n个作为检测纠缠对,利用CHSH不等式进行信道检测;发送序列中剩余n+δ个EPR纠缠对变形为非正交的量子态作为密钥,将广播明文信息分组编码成密文,利用量子态的不精确克隆复制M份发送给每个目的节点;目的节点接收密文逆向解密。分析了通信的吞吐量、信道的利用率、协议的安全性等问题。通过分析,证明该协议能有效防止特洛伊木马攻击,保证多播信息的安全。
[Abstract]:A multicast communication protocol against Trojan horse attack in a network composed of a source quantum node and M destination quantum nodes is proposed. The source quantum nodes construct 2n 未 EPR entanglement pairs and send sequence tags. In the transmission sequence, n pairs are randomly selected as detection entanglement pairs, and the channel is detected by using CHSH inequality, and the remaining n 未 EPR entanglement pairs in the transmission sequence are transformed into non-orthogonal quantum states as keys, and the broadcast plaintext information is coded into ciphertext by grouping the broadcast information into ciphertext. The imprecise cloning of quantum states is used to copy M copies to each destination node, and the destination node receives the reverse decryption of the ciphertext. The communication throughput, channel utilization and protocol security are analyzed. Through analysis, it is proved that this protocol can effectively prevent Trojan horse attack and ensure the security of multicast information.
