A generating apparatus 210 provides certification data to a receiving apparatus 220 (S301). The receiving apparatus 220 transmits a certification request requesting a certification that the second public key PK2 is in a parent-child relationship with the first public key PKI to a certifying apparatus 230 (S302). In this example, the certification request includes the certification data, but if the certification data is provided directly from the generating apparatus 210 to the certifying apparatus 230, the certification request does not need to include the certification data. The certifying apparatus 230 verifies the certification data by calculating a verification formula for the certification data in response to the certification request (S303)."},"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 for same","description":"The reliability of a second public key which is part of a second key pair generated in association with a first key pair is certified.
