The method comprises: selecting, by a transmitter according to a basis selection rule, a basis of preparation for transmitter authentication information that is generated with a first pre-provisioned algorithm and varies dynamically, and transmitting quantum states containing key information and the transmitter authentication information; and measuring, by a receiver, quantum states of the transmitter authentication information according to the basis selection rule, and ending the QKD process if a measurement result is inconsistent with corresponding information calculated with the first pre-provisioned algorithm. By means of this technical solution, dynamic authentication of a requestor of QKD can be achieved in a QKD process, a defense can be provided against spoofing attacks, man-in-the-middle attacks and distributed denial of service (DDoS) attacks, and the security of the QKD process is improved; furthermore, a waste of quantum key resources can be avoided as well."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Authentication method, apparatus and system used in quantum key distribution process","description":"The present application discloses an authentication method used in a QKD process, and further discloses additional authentication methods and corresponding apparatuses, as well as an authentication sy","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10505724","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
