    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: A content sharing method performed in a content redistribution device based on a non-realtime IPTV service includes transmitting a secret key in password information of a user of the content redistribution device to an IPTV service server and storing a public key corresponding to the secret key; and transmitting an event message for content request to the IPTV service server to request a non-realtime IPTV service. Further, the content sharing method includes receiving contents requested in the event message for content requesting from the IPTV service server; and decoding the received contents and encrypting the decoded contents using the public key. Furthermore, the content sharing method includes transmitting the contents encrypted using the public key to content recipient devices; and generating an event message for content sharing using the public key to transmit the generated event message to the content recipient devices.
