摘　　要：量子密码凭借量子叠加和纠缠等物理原理实现了超越经典密码的安全性,受到多个领域的高度关注。半量子密码只需要一个用户具备完全的量子能力,而其他用户仅需简单的量子操作,降低了大多数用户对复杂量子设备的依赖,在理论研究和实际应用中具有重要的研究价值和意义。为实现量子资源有限条件下的量子密码协议设计,通过聚焦半量子密码的发展历程,系统梳理了半量子密钥分发、半量子安全直接通信、半量子秘密共享、半量子隐私比较以及半量子安全多方求和等半量子密码协议的研究进展。此外,对半量子密码协议的一些开放问题和未来研究方向进行讨论,为从事相关研究工作的学者提供参考,促进该领域的发展和创新。Quantum cryptography leverages physical principles such as quantum superposition and entanglement to achieve security levels beyond classical cryptography,attracting significant attention across various fields.Semi-quantum cryptographyrequires only one user to possess full quantum capability,while others need only perform basic quantum operations,reducing reliance on complex quantum devices formost users.This approach holds substantial research value and significance in theoretical exploration and practical applications.In order to realize the design of quantum cryptographic protocols with limited quantum resources,this study focuses on the development of semi-quantum cryptography,systematically reviewing the progress of semi-quantum key distribution,semi-quantum secure direct communication,semi-quantum secret sharing,semi-quantum privacy comparison,and semiquantum secure multi-party summation.Furthermore,some open issues and future research directions in semi-quantum cryptographic protocols are discussed,aiming to provide references for scholars engaged in related research and promote the development and innovation of this field.
