摘要： An authentication apparatus for a non-real-time IPTV system decrypts a first encrypted value included in a contents request message received from a device using a preset session key, and then verifies the validity of the contents request message. If the verification results of the contents request message are valid, the authentication apparatus encrypts a variation between timestamps of the authentication apparatus and the device using the session key, and then generates a second encrypted value. After verification information by which the device is capable of verifying the authentication apparatus has been generated using the second encrypted value, the authentication apparatus sends verification information, together with contents corresponding to the contents request message, to the device.
摘要翻译：用于非实时IPTV系统的认证装置使用预设会话密钥来解密从设备接收到的内容请求消息中包含的第一加密值，然后验证内容请求消息的有效性。如果内容请求消息的验证结果有效，则认证装置使用会话密钥对认证装置的时间戳和装置的变化进行加密，然后生成第二加密值。在使用第二加密值生成了能够验证认证装置的认证信息的认证信息之后，认证装置将与内容请求消息对应的内容的验证信息发送到设备。
