Embodiment Construction

[0034] 1. Add media files in the media center

[0035] Encrypt the media file through the AES symmetric encryption algorithm, and add the name of the rights object file (Rights Object) corresponding to the media file before the encrypted media file; the name of the rights object file and the encrypted media file form the media encryption in the ECP package part (Content);

[0036] Use the SHA-1 and RSA algorithm to digitally sign the media encryption part (Content) generated in the previous step to generate the signature part (Signature);

[0037] Then generate a descriptive header (Header), which contains information such as media file name, file length, rights object name, digest and signature length;

[0038] Then, splicing the generated parts (Header, Content, Signature) and digesting the message of this union to generate a digest part (Digest); finally, splicing these parts (Header, Content, Signature, Digest), Compose a media ECP package and add it to the media library...

Description

technical field [0001] The invention relates to an authentication method based on data exchange between a playing media terminal and an authentication center through a network, in particular to an authentication method for public safety broadcast control media management and identification of its integrity and untampered. Background technique [0002] Two years ago, LCD TVs that could broadcast advertisements in a loop quietly entered commercial buildings and commercial buildings, quietly lifting the new veil of public media. Who would have thought that two years later, this small "thin-plate advertising machine" would have such a large market potential and become the new favorite of the software industry, integrated electronics industry and advertising industry. From fixed terminals in major commercial buildings, supermarkets and hospitals, to mobile terminals on subways and buses, we provide various information services related to basic necessities of life for the constant...
