The trusted node has a tamper detection module and a secure memory. The tamper detection module deletes critical system parameters responsive to detecting physical tampering. The trusted node, as the first endpoint trusted node, exchanges a quantum key, encrypts data and transmits encrypted data. The trusted node as the middle-trusted node exchanges a quantum key, exchanges another quantum key, decrypts and re-encrypts data and transmits encrypted data. The trusted node as the second endpoint trusted node exchanges a quantum key, and decrypts data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Tamper detection in a quantum communications system","description":"A tamper detecting component for a quantum communication system is a trusted node, configurable as a first endpoint trusted node, a middle-trusted node and a second endpoint trusted node.
