Abstract
SMPCP is a multicast watermark scheme to protect valued contents from illegal distribution. However, it requires an overhead of O(N) on cryptographic encryptions and message size, here N is the size of group members. This paper proposes a logical key tree based secure multicast protocol, LKT-SMPCP, to improve the overhead in the SMPCP. Experimental results show that LKT-SMPCP reduces the encryption overhead by 30% as compared with the original SMPCP.
