REAL TIME ENCRYPTION IMPLEMENTATION METHOD FOR THE CONTENTS PROTECTION ON THE DMB-TERMINAL

机译:DMB终端内容保护的实时加密实现方法

摘要

PURPOSE: A real time encryption implementation method for the contents protection on the DMB-terminal is provided to encrypt only minimal payload by analyzing the transmission stream of DMB contents. CONSTITUTION: The encryption part is set in the transmission stream. The PMT, PAT, and PES packets included in the transmission stream are classified. The coding object is set by distinguishing the payload part of the PES packet. The encryption of the contents is implemented for the set part. The encryption of more than 128 bit is implemented by using the block encryption or the stream encryption.
