Quantum secure communication network is in the stage of rapid construction. As classical networks, we researchers also need to develop different practical quantum protocols for different application scenarios in quantum communication network. However, complex quantum operations and expensive quantum resource preparation seriously hinder the practical development of quantum communication networks. A variety of quantum signature protocols play an important role in quantum communications; however, these protocols also face the same problems described above. In this paper, we propose a semi-quantum proxy signature scheme with quantum walk-based teleportation to solve these problems. Proxy signer TP as the quantum participant and original signer Alice is the classical participant. We introduce quantum walk teleportation to generate quantum entanglement resource naturally in signature phase, which seems more in line with the reality of quantum communication networks. Security analysis show that this scheme meets all the security requirement of quantum proxy signature protocol, and the qubit efficiency analysis also proves this protocol has better practical value.

具有基于量子行走的隐形传态的半量子代理签名方案

量子保密通信网络正处于快速建设阶段。作为经典网络,我们研究人员还需要针对量子通信网络中的不同应用场景开发不同的实用量子协议。然而,复杂的量子操作和昂贵的量子资源制备严重阻碍了量子通信网络的实际发展。多种量子签名协议在量子通信中发挥着重要作用;然而,这些协议也面临着与上述相同的问题。在本文中,我们提出了一种基于量子行走的隐形传态的半量子代理签名方案来解决这些问题。代理签名者 TP 作为量子参与者,原始签名者 Alice 是经典参与者。我们引入了量子行走隐形传态,在签名阶段自然产生量子纠缠资源,这似乎更符合量子通信网络的现实。安全性分析表明,该方案满足量子代理签名协议的所有安全要求,量子位效率分析也证明该协议具有较好的实用价值。
