论文摘要
我们重新访问了Gottesman在2003年提出的无统治加密。我们介绍了不可吻合的加密和关键回收的组合，同时旨在提高低通信的复杂性和较高的速率。我们引入了一个基于Qubit的准备和测量无统治的加密方案，并使用可重复使用的密钥。我们的方案由爱丽丝的单个传输和鲍勃的单个经典反馈钻头组成。从爱丽丝到鲍勃的传播完全由量子台组成。该速率定义为消息长度除以量子数的数量，高于使用Gottesman的方案可以实现的速度。考虑到噪音，我们根据钻石规范距离提供安全证明。
We re-visit Unclonable Encryption as introduced by Gottesman in 2003. We look at the combination of Unclonable Encryption and Key Recycling, while aiming for low communication complexity and high rate. We introduce a qubit-based prepare-and-measure Unclonable Encryption scheme with re-usable keys. Our scheme consists of a single transmission by Alice and a single classical feedback bit from Bob. The transmission from Alice to Bob consists entirely of qubits. The rate, defined as the message length divided by the number of qubits, is higher than what can be achieved using Gottesman's scheme. We provide a security proof based on the diamond norm distance, taking noise into account.
