Patent number: 11917076Abstract: [Problem] To provide a terminal registration system and a terminal registration method for improving user convenience in registration of a new terminal to a plurality of service sites. [Solution] The registered terminal 1 includes an Authenticator 10 including service site list information 110 that associates private keys and URLs for access to service sites with each other. A Registration Manager 100 acquires the service site list information 110 from the Authenticator 10 of the registered terminal 1. Then, the Registration Manager 100 performs FIDO authentication for a registration target service site using a private key of the registered terminal 1, on the basis of the acquired service site list information 110, and performs Registration of a newly generated cryptographic key at the new terminal 2.Type: GrantFiled: May 25, 2022Date of Patent: February 27, 2024Assignee: Nippon Telegraph and Telephone CorporationInventors: Hideo Nishimura, Takao Yamashita, Yasuhiko Yoshimura, Satoru Furukawa
