Design and analysis of overlay multicast watermarking protocol based on GSAKMP
Tao Wang · Jisuanji gongcheng yu sheji · 2008
GSAKMP is a key-management protocol framework for multicast and group security.Based on the analysis of cryptographic key-related mechanisms of GSAKMP,using some knowledge about multicast watermarking,a secure overlay multicast watermarking protocol which includes both data confidentiality and copyright protection,is designed and analyzed.It is important for stream media transmission where the leaking identification is needed.
