Problems solved by technology

The openness and interactivity of IPTV technology enable IPTV to provide new applications that traditional analog TV and digital TV cannot provide, but it also creates new, more serious and complex security issues: On the one hand, the IPTV technology Openness, interactivity and other characteristics allow attackers to spread harmful content without using more professional attack methods such as attacking satellite channels and inserting broadcasts on cable TV lines. The attack methods are more concealed and less costly; on the other hand, Compared with traditional analog TV and digital TV, IPTV technology has a lower cost of providing TV services, and it is more difficult to supervise the content of the provided TV services, making it more convenient for hostile forces at home and abroad to use IPTV technology to spread reactionary program content , causing serious social stability problems
The former focuses on conditional acceptance in the field of digital TV, while the latter focuses on copyright protection of digital content, neither of which considers the content supervision needs of IPTV, so it cannot be applied to IPTV content supervision

Embodiment Construction

[0019] The IPTV content security supervisory method that the present invention proposes, its principle block diagram is as follows figure 1 As shown, firstly, the sender applies to the key management center for a content supervision key; the key management center generates a pair of public-private key pairs for the sender, stores the public-private key pair in the content supervision key table, and notifies the receiver according to The public-private key pair updates the terminal content supervision key table, and returns the public-private key pair and the content supervision key serial number corresponding to the public-private key pair to the sender; Perform sampling to obtain a sampling address set, use the content hashing method to hash the contents of the sampling address set to obtain a hash value; the sender generates a content supervision mark, and sends the The calculation parameters and the above hash value are stored in the content supervision mark; the sending en...

Abstract

The invention relates to a safety supervision method for IPTV content in IP network environment by embedding a content supervision label bund with content in IPTV content flow. Wherein, binding the IPTV content and label with a address sample method and content hash method, signing with label with digital signature method to embed into the IPTV content flow for transmission; on receive end, calculating again and comparing the hash value to determine the content unjuggled, and using digital signature to guarantee the data integrality and truth of label.

Description

technical field [0001] The invention relates to a method for safety supervision of Internet TV content, in particular to a method for safety supervision of Internet TV (hereinafter referred to as IPTV) content based on the Internet Protocol (hereinafter referred to as IP) network environment, and belongs to the technical field of information dissemination. Background technique [0002] Since the beginning of the 21st century, with the development of broadband network, streaming media, codec, information encryption and storage technology, the video service based on Transmission Control Protocol / Internet Protocol (TCP / IP) network, that is, IPTV, has begun to enter commercial operation. stage. The openness and interactivity of IPTV technology enable IPTV to provide new applications that traditional analog TV and digital TV cannot provide, but it also creates new, more serious and complex security issues: On the one hand, the IPTV technology Openness, interactivity and other ch...
