摘要

提出一种新的量子多方隐蔽通信方案，根据伪随机序列从共享纠缠密钥集中选择随机子集用于多方加密方案，利用量子信道噪声的掩盖将敏感信息伪随机旋转并伪装到量子纠错码中. 利用伪随机序列选择共享密钥子集补构造侦测子集，采用判断典型错误机制实现密钥的循环使用. 相比于其他隐蔽通信方案密钥消耗量大的缺点，该方案显著降低了密钥消耗，优化了共享密钥子集补判断典型错误的检测机制检测窃听的功能. 分析了抵抗特洛伊木马攻击的能力.

Abstract

A novel scheme of quantum multi-party covert communication is proposed. Using a pseudo-random
sequence, the random subset is selected from a set of Greenberger-Horne-Zeilinger (GHZ) shared private-key forencryption. Quantum information is rotated and hidden by disguising it as noise in a quantum error-correcting
code. A subset of detection is constructed and based on the complement of shared private-keys. Based on the
detection scheme of typical error, the private-key can be recycled. Compared to other protocols which require
more private keys, the proposed scheme can significantly reduce key consumption. The ability of eavesdrop
detection is optimized. The optimized scheme is robust to the Trojan horse attacking.

Key words： information security; covert communication; quantum cryptography; entanglement private-key
