The system is a three-layer structure formed by a physical layer, a key layer, and an application layer. The physical layer is a key generation terminal and is used to generate a key string for signature in real time; the key layer is used to store the key string generated by the physical layer and provide a required key to the upper layer, namely, the application layer when required; and the application layer is a transceiving software part in the mail system, and is used to extract keys generated by the physical layer from the key layer so as to encrypt information to be sent. The mail transceiving method comprises: a quantum key distribution (QKD) phase, a mail signature phase, and a signature verification phase."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"QDS-based mail system and transceiving method","description":"A Quantum Digital Signature (QDS)-based mail system and a transceiving method are provided.
