光包加密是提高 ASON(自动交换光网络)安全性的基础。在分析光包加密机制及相关研究现状的基础上，根据 ASON分层体系架构及BB84量子密钥分配协议的特点，提出了一种改进的基于四层结构的ASON量子交换机模型；基于该模型，提出了一种基于秘密共享加密的多路径量子密钥分配策略，用于解决长距离传输量子密钥的问题。仿真结果表明该方案是可行的。

Optical packet encryption is the foundation for improving the security of Automatically Switched Optical Networks (ASON).On the basis of analyzing the optical packet encryption mechanism and the status of the relevant researches and ac-cording to the layered architecture of ASON and the characteristics of BB84 quantum key distribution protocol,this paper pres-ents an improved four-layer architecture-based ASON quantum switch model.Using this model,it proposes a secret sharing encryption-based multi-path quantum key distribution scheme,which is used for long-distance transmission of quantum key. Simulation experiment results verify the feasibility of this scheme.
