A processor generates a first encrypted polynomial by encrypting a first polynomial that corresponds to a first binary vector obtained by performing a binary transformation on elements of the first vector. A transmitter transmits to a cryptographic operation device cryptographic information that represents the first encrypted polynomial. The cryptographic operation device multiplies the first encrypted polynomial by a second encrypted polynomial that is generated by encrypting a second polynomial that corresponds to a second binary vector obtained by performing a binary transformation on elements of a second vector, so as to generate a third encrypted polynomial. When assigning 2 to a variable in a prescribed portion of a third polynomial obtained by decrypting the third encrypted polynomial, a result of an operation of the first vector and the second vector is obtained."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Cryptographic processing device and cryptographic processing method","description":"A memory stores therein a first vector.
