Research on Encryption Technology for the Streaming Media
Wanfang Liu · 2006
Based on characteristics of encryption technology,this paper conducts an in-depth study of encryption / decryption mechanism for streaming media from technical aspect of traditional passwords.Factors to be considered for real-time streaming media encryption methods are analyzed.The requirement of MPEG-1 data stream real-time encryption can be satisfied only when realization is derived of the decipher speed [the data packet to be long/(This frame designates decoding time minus this final data packet arrival time].The purpose of implementing multimedia data real-time encryption protection depends on how target is unified with traditional password technology and emerging stream media technology.
