Research, Design And Implementation Of IPTV-Based Digital Rights Anagement

This paper studies, analyses, designs, realizes the digital rights management of the TV program content based on the IPTV service platform.After the introduction of digital rights management system, soever pirates anywhere in the broadband network to intercept, the worst case, only get the encrypted TV program data, and can not access non-encrypted TV program data. That is, non-encrypted TV program data, the encrypted TV program data which is not authorized can not be used normally. Even though pirates get the data, there was no sense.Encrypted program data transmitted to the set-top boxes, after the identity confirmation that get through the set-top box's DRM agent, licensing system may apply for copyright authorization object which is binded with the user identity, legitimate users of the object that own the copyright may be able to parse correctly the copyright authorization object, according to data in the object of copyright authorization get the program decryption key, decrypt the encrypted TV program data.At the same time forbid set-top box to save the decrypted TV program data, preventing decrypted TV program data is illegally read on the set-top boxes.In this paper, main tasks are as follows:Participated the overall design and implementation of the subject,completed the analysis of digital rights management based on IPTV,.During this period, the main achievements include:1.Design and implement adopting the AES, DES High-strength encryption algorithm to encrypt the TV program content, increase the security and the crack difficulty.2.Design and implement adopting the RSA algorithm to generate public private key pair successfully, improve the system security and the crack difficulty.3.Design and implement adopting the Sha-1, MD5 algorithm to get the Message Digest from permission file successfully, ensure the integrity of permission file.4.Design and implement adopting the Open Digital Rights Language (ODRL) to express the penniss object successfully which is the international standards, ensure the platform with more versatility and compatibility.5.Design and implement the SSL secure transmission for content, and reached a high of concurrent efficiency.
