Yang Yi-xian · Jisuanji gongcheng · 2012
A new security model of Digital Rights Management(DRM) for Set-top Box(STB) is proposed,in which content object and rights object are separated respectively,and the content object is encrypted by Content Encryption Key(CEK),while rights object is encapsulated by user’s device related key.Mutual authentication is realized for users’ and server’s trust management.Experimental results show that the technologies of cryptography,digital signature and authority management are developed for controlling the use of high definition contents,MTV,TV media magazines.
