A controlled deterministic secure semi-quantum communication protocol based on GHZ-like states is proposed for improving the security of semi-quantum communication. The protocol includes three participants, one is Alice with quantum capabilities who can prepare GHZ-like states to provide a secure and controllable quantum channel, and the remaining are Bob and controller Charlie who have only classical abilities. During the communication process, Bob compresses the secret message to obtain a binary string with Huffman compression coding technology, and then performs encoding and encryption operations to improve confidentiality. Furthermore, the analysis results demonstrate that the proposed CDSSQC protocol can effectively resist Trojan horse attacks, intercept-resend attack, double CNOT attack and other attacks.

为了提高半量子通信的安全性，提出了一种基于类GHZ状态的受控确定性安全半量子通信协议。该协议包括三个参与者，一个是具有量子能力的爱丽丝，可以准备GHZ样的状态以提供安全且可控制的量子通道，其余的是鲍勃和控制器查理，他们只有经典能力。在通信过程中，鲍勃使用霍夫曼压缩编码技术压缩秘密消息以获得二进制字符串，然后执行编码和加密操作以提高机密性。此外，分析结果表明，所提出的CDSSQC协议可以有效抵御特洛伊木马攻击，拦截重发攻击，双重CNOT攻击等攻击。
