论文摘要
量子密码学 - 已广泛研究了量子计算技术在密码学上的应用。量子密码学的两个主要方向是量子密钥分布（QKD）和量子加密，前者专注于安全钥匙分布，后者专注于使用量子算法进行加密。与QKD的成功相反，量子加密算法的开发仅限于大多数不适合大多数通信需求的一次性垫（OTP）的设计。在这项工作中，我们建议使用量子状态创建过程加密消息的非OTP量子加密方案。本质上，作为一个非OTP量子块密码，该方法反对具有以下特征的现有方法：1。复杂的键 - 文字关系（即混淆）和复杂的plaintext-ciphertext Relation（即扩散）； 2。多个块上实用加密的操作模式。这些功能提供了关键的可重复性和防止窃听和标准隐式攻击的保护。
Quantum cryptography -- the application of quantum computing techniques to cryptography has been extensively investigated. Two major directions of quantum cryptography are quantum key distribution (QKD) and quantum encryption, with the former focusing on secure key distribution and the latter focusing on encryption using quantum algorithms. In contrast to the success of the QKD, the development of quantum encryption algorithms is limited to designs of mostly one-time pads (OTP) that are unsuitable for most communication needs. In this work we propose a non-OTP quantum encryption scheme utilizing a quantum state creation process to encrypt messages. As essentially a non-OTP quantum block cipher the method stands out against existing methods with the following features: 1. complex key-ciphertext relation (i.e. confusion) and complex plaintext-ciphertext relation (i.e. diffusion); 2. mode of operation design for practical encryption on multiple blocks. These features provide key reusability and protection against eavesdropping and standard cryptanalytic attacks.
