Abstract

The invention relates to an IPTV (Internet Protocol Television) user security terminal which comprises an identity authentication module, an authorization information decryption module, an authorization storage and management module, a key storage and management module, a key decryption module, a content descrambling module, an uplink information encryption module, a decoding module and a user input module, wherein the identity authentication module comprises an elliptic curve cryptosystem signature module and an elliptic curve cryptosystem verification module. The terminal ensures that only authorized users can watch programs based on good interactivity of the IPTV by means of identity authentication, authorization management, secret key encryption protection, content encryption protection and the like. The user security terminal has favorable expansibility, can satisfy live broadcast, VOD broadcast and other services of the IPTV, and can effectively protect the security of the digital media content of the IPTV.

Description

technical field [0001] The invention relates to IPTV (Internet Protocol Television) security application technology, in particular to an IPTV user security terminal. Background technique [0002] IPTV is a media service based on broadband Internet, with digital audio and video resources as the main body, and TVs, computers, etc. as display terminals. It is a new service generated after the integration of Internet services and traditional TV services. IPTV is an open and interactive audio and video content and business management system based on content management. Since there are many security risks in the process of broadcasting digital program content on the IP network, effective copyright management can realize copyright protection of audio and video programs. and legitimate consumption. To protect the security of IPTV digital media content copyright, it is necessary to establish a set of security mechanisms including encryption, authentication, and rights management. By...
