    • An e-mail terminal device capable of carrying out a printing process, a storing process or the like of only e-mail with a signature or only e-mail with a signature of a trustable Certificate Authority (CA). When receiving e-mail, a determination is made as to whether or not the e-mail requires a signature. When the e-mail requires a signature, a determination is made as to a presence or an absence of the signature, whether or not a verification result of the signature is proper, and whether or not a CA issuing a public key used for the verification of the signature is trustable. When a signature is not attached, when the signature is improper, or when the CA is untrustable, the printing process is not executed. E-mail requesting retransmission of e-mail with a signature or e-mail signed by a secret key of a trustable CA is transmitted to a transmitter.
    • 一种电子邮件终端装置,其能够仅具有签名的电子邮件的打印处理或存储处理等,或仅具有可信赖的证书颁发机构(CA)的签名的电子邮件。 收到电子邮件时,确定电子邮件是否需要签名。 当电子邮件需要签名时,确定签名的存在或不存在,不管签名的验证结果是否合适,以及是否发行用于验证的公钥的CA 的签名是可信赖的。 当签名未附加时,签名不正确或CA不可信任时,不执行打印过程。 通过可信赖CA的秘密密钥签名的签名或电子邮件请求重发电子邮件的电子邮件被发送到发送器。

    • An encryption device which enables a client not having an encryption function to easily use a function of encrypted mail without carrying out a management of certification and a key and an encryption and a decryption. When an Internet facsimile machine transmits electronic mail to an encryption device, the encryption device converts the received electronic mail into encrypted mail and transmits to a mail server. When another Internet facsimile machine transmits data including a part to be encrypted and transmission destination information as a main body of mail to an encryption and decryption I/F of the encryption device, the encryption device encrypts the main body of the received mail under a prescribed encryption method and sends back to the other Internet facsimile machine. Accordingly, the other Internet facsimile machine can format encrypted data into encrypted mail and transmit to a remote Internet facsimile machine.
    • 一种加密装置,其使得不具有加密功能的客户端能够容易地使用加密邮件的功能,而不进行认证和密钥的管理以及加密和解密。 当因特网传真机将电子邮件发送到加密设备时,加密设备将接收到的电子邮件转换为加密邮件并发送到邮件服务器。 当另一个互联网传真机将包括要加密的部分的数据和作为邮件的主体的发送目的地信息的数据发送到加密装置的加密和解密I / F时,加密装置根据规定的加密方式对接收到的邮件的主体进行加密 加密方式并发送回其他互联网传真机。 因此,其他因特网传真机可以将加密的数据格式化为加密的邮件,并传送到远程的互联网传真机。
