Also, the registration apparatus accepts a plaintext M and attribute information B. The registration apparatus executes a function F_2 by taking as input a concatenated value of an attribute value of each level j in the attribute information B and a number of each level j, executes a function F_3 by taking as input a function value of the function F_2, calculates an attribute element C_{j, 0, 0} that is an exclusive-or of a function value of the function F_3 and a jth random number of the data random number tuple R, executes a function F_4 by taking as input the plaintext M and an exclusive-or of the data random number tuple R, and generates encrypted data C that includes the attribute element C_{j, 0, 0} and a ciphertext C_{L+1} which is a function value of the function F_4. Then, the registration apparatus registers the encrypted data C in a data management apparatus."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Registration apparatus, search operation apparatus, data management apparatus","description":"A registration apparatus generates a data random number tuple R that is a tuple of random numbers whose quantity is the same as a level quantity L of a hierarchy that a user attribute forms, and that ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11233629","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.
