摘要： At the user authentication apparatus 30, an identifier of a certification authority (CA) certificate that a CA information disclosure server 20 discloses in advance is registered in an identifier list of the CA. At the user terminal 10, a key pair consisting of a terminal public key and a terminal secret key is generated, the terminal signature is generated for information containing the terminal public key using the CA secret key acquired in advance, and a self-signed certificate of the same form as the certificate issued from CA, that is, a terminal certificate containing at least a terminal public key, a terminal signature, and a CA identifier, is created and stored, and registered in the user authentication apparatus 30. The terminal certificate having the same issuer information as the CA identifier in the identifier list of the CA notified from the user authentication apparatus 30 at the time of the service request is selected, and user authentication in accordance with a well-known user authentication protocol is executed using the terminal certificate.
摘要翻译：在用户认证装置30中，CA信息公开服务器20预先公开的认证机构（CA）证书的标识符登记在CA的标识符列表中。在用户终端10，生成由终端公开密钥和终端密钥构成的密钥对，使用预先获取的CA密钥生成包含终端公钥的信息的终端签名，以及自签名证书与从CA颁发的证书相同的形式，即至少包含终端公钥，终端签名和CA标识符的终端证书被创建并存储，并登记在用户认证装置30中。终端选择在服务请求时从用户认证装置30通知的CA的CA标识符列表中具有与CA标识符相同的发行者信息的证书，并且根据公知的用户认证协议进行用户认证，使用终端证书。

摘要： A secret key of a second apparatus is stored in a relay apparatus. A first apparatus specifies secret information used to identify a common key, generates encrypted secret information by encrypting the secret information by using a public key of the second apparatus, and transmits the encrypted secret information to the relay apparatus. Then, the relay apparatus decrypts the encrypted secret information by using the secret key of the second apparatus to extract the secret information. The relay apparatus transmits the encrypted secret information to the second apparatus. The second apparatus decrypts the encrypted secret information by using the secret key of the second apparatus to extract the secret information. Finished messages corresponding to communication log information and the secret information are exchanged between the first apparatus and the relay apparatus and between the second apparatus and the relay apparatus.
