Abstract
An anonymous credential authentication system receives an anonymous credential signature value indicating that setting proposition information using a credential is satisfied from a user device that has been issued the credential combined with multiple pieces of attribute information constituting personal information, generates signer authentication information that confirms a signer of the anonymous credential signature value using an opening key, and outputs the signer authentication information.
