A generator 210 calculates and stores x·H(n) which is proof data and ax·H(n), when the second public key ax·g1 which is of the second key pair is generated (S301). The generator 210 provides the calculated proof data to a receiving apparatus 220 (S302) which has received the proof data, transmits a proof request to the proving apparatus 230 for requesting a proof that the second public key ax·g1 is generated by an owner of the first public key a·g1 (S303). In response to the proof request, the proving apparatus 230 verifies the proof data by calculating a verification formula for the proof data (S304). The proving apparatus 230 transmits the verification result as a response to the proof request from the receiving apparatus 220 (S305)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device and method for certifying reliability of public key, and program therefor","description":"Proving reliability of a second public key of a second key pair generated in association with a first key pair.
