摘　　要：量子通信是近年来发展的新型交叉学科,是量子论和信息安全论相结合的新研究领域。量子密钥分发(Quantum Key Distribution,QKD)是最先实用化的量子通信技术,其需求主要包括小型化、低成本、应用场景等。当前应用主要局限于传输距离有限,需要专用基础设施。针对目前存在的问题,基于Shamir密钥共享算法设计了一种密钥共享策略,使处于不同QKD网络内的用户可直接通过量子密钥进行加密通信。Quantum communication is a new cross discipline developed in the past years,which is a new research field combining quantum theory and information security theory.Quantum Key Distribution(QKD)is the first practical quantum communication technology.Its requirements mainly include miniaturization,low cost,application scenarios,etc.The current application is mainly limited by the limited transmission distance and the need for special infrastructure.In view of the existing problems,a key sharing strategy is designed based on Shamir key sharing algorithm,so that users in different QKD networks can directly use quantum keys for encrypted communication.
