    • An opt-in email system in which a recipient that has opted in to an email list can recognize and trust that an email has actually come from a desired sender. When a recipient desires to opt-in to an e-mail list, the recipient is sent to a trusted third party certification service that generates a certificate associated with a key pair. A key is maintained at the sender's location by a secure cryptographic device that can verify the certificate and create a signature, using a key of the key pair, for messages intended for the recipient. When a message intended for the recipient is received from the sender, the signature will be verified based on the status of the certificate and the corresponding key of the key pair. If the signature does not verify, it indicates that the recipient has not opted-in to receive emails from this sender.
    • 选择加入电子邮件系统,其中选择加入电子邮件列表的收件人可以识别并相信电子邮件实际上来自所需的发件人。 当收件人希望选择加入电子邮件列表时,收件人将被发送到生成与密钥对关联的证书的受信任的第三方认证服务。 密钥由安全加密设备保持在发送者位置,该密码设备可以使用密钥对的密钥来验证证书并创建签名,用于发送给接收者的邮件。 当从发送者接收到用于接收者的消息时,将基于证书的状态和密钥对的相应密钥验证签名。 如果签名未验证,则表示收件人未选择接收来自此发件人的电子邮件。
