The communication unit communicates with a calculation apparatus and a determination apparatus. In the calculation apparatus, encrypted registration data obtained by encrypting registration data twice, once with the first key and once with a second key, is registered. The registration data is data against which the authentication object data is verified. The determination apparatus uses the second key upon the authentication. When registering the encrypted registration data in the calculation apparatus, the computing unit generates a key different from the first key, generates encrypted data by encrypting the registration data twice, once with the first key and once with the different key, transmits the different key to the determination apparatus, and the encrypted data to the calculation apparatus, through the communication unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for cryptographic processing","description":"A cryptographic processing apparatus that holds a first key, and receives authentication object data upon authentication includes a communication unit and a computing unit.
