The method includes communicating the first linearity and the first proximity ciphertexts to a server. The method includes encrypting a second plaintext vector using the relational linearity encryption scheme to generate a second linearity ciphertext and using the relational proximity encryption scheme to generate a second proximity ciphertext. The method includes communicating the second linearity and second proximity ciphertexts, a relational linearity key, and a relational proximity key to the server. The method includes receiving an authentication signal indicative of a linearity relationship between the first and the second linearity ciphertexts discovered using the relational linearity key and of a proximity between the first and the second proximity ciphertexts detected using the relational proximity key."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Relational encryption","description":"A method includes encrypting a first plaintext vector using a relational linearity encryption scheme to generate a first linearity ciphertext and using a relational proximity encryption scheme to gene","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9749138","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.
