摘要
为了保证流媒体传输的基本安全需求和维护商家的利益,提出一个新的流媒体安全传输技术模型。该模型从加密算法、流媒体传输、用户身份等方面对现有的数字版权管理方案进行改进,可完成包括视频、音频或多媒体文件等在内的数字商品的授权、使用和转让。同时,该模型还能够提高流媒体传输的效率、增强其安全性,具有一定的实用价值。
To ensure the essential security requirement for transfering streaming media and safeguard the interest of the merchant, a new streaming media secure transfor model is proposed in this paper. The new model improves the encryption algorithm, streaming media transmission and the identity authentication of the existing digital rights management model, and could realize the authorization, utilization and transfer of video, audio, multimedia, and other digital products. At the same time, this model could also mprove transfer efficiency of streaming media enhance its security, and thus is of certain practical value.
