Abstract (in Japanese) (See Japanese page) 
(in English) It is difficult to sufficiently protect web accounts using a password-based authentication method against threats of many types of security attacks and hackings. A highly secure authentication method without using passwords has been standardized by FIDO Alliance in order to improve weak security of password-based authentication, where the number of companies and governments joining to FIDO Alliance is rapidly increasing. In this paper, we focus on the authentication method standardized by FIDO Alliance and analyze problems in terms of security, usability and operation cost. In addition, we propose a key management solution and evaluate our solution in terms of relationship between web service providers.
