The attacks detection relies on both the random modification of the setting parameters of the said single-photon detector(s) and the comparison of the measured detection probability values for each setting parameter with the expected detection probability values. The modified parameter of the single-photon detector can be its efficiency or its timing of activation for example."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for the detection of attacks taking control of the single photon detectors of a quantum cryptography apparatus by randomly changing their efficiency","description":"An apparatus and method for revealing both attack attempts performed on the single-photon detector(s) of a quantum cryptography system and Trojan horse attack attempts performed on quantum cryptograph","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9634835","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.
