摘要：The improvement of computer communication and information processing technology brings the activation of multi-media content. The government tries to expand the development of cultural content into the national enterprise for promoting a growth foundation in an information-oriented society. This paper proposes an encryption method of multi-media data using a hash chain algorithm for secure multi-media contents and designs an authentication protocol using an authentication and key transmission algorithm for identifying an authorized user. Finally, this paper proposes the decryption method of multi-media content in real-time using a effective buffer scheduling method by constructing a duplicated buffer to minimize the delay time of playback at the decryption procedure.
