The arithmetic evaluation function is performed on a ciphertext input homomorphically encrypted from a plaintext input using a set-system including sets having an intersection property. The ciphertext output is decrypted using a summation of two or more noise-canceling party identifiers of two or more authorized parties, wherein the intersection property of the sets cancels out errors generated during the decrypting operation for the two or more authorized parties."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Enforcing access structures in fully homomorphic encryption","description":"A homomorphic encryption system receives a ciphertext output of an arithmetic evaluation function.
