ACCESS CONTROL METHOD FOR SUBSCRIBER AUTHENTICATION IN IPTV

摘要

PURPOSE: An access control method is provided to effectively confirm subscribers by using a finger print value and age information. CONSTITUTION: A management server(120) transmits identification information to a smart card(140). An STB(Set Top Box)(160) calculates a session key based on the identification information. The STB generates an age grade hash value. The STB decodes an encoded control word received from the smart card through the calculated session key. The STB provides the corresponding content to the authenticated user.
