A novel MPEG video encryption scheme for protecting MPEG coded video in collaborative domains
Sherif A. Halawa, Hassan M. A. Elkamchouchi · 2008
Recently, the increase in average streaming speed over the Internet has paved the way for a new form of collaboration to threaten the security of existing video ciphers. In this paper, we present this collaborative attack and prove the vulnerability of existing video encryption schemes to this form of attacks. We then propose an improved video cipher that is immune against collaboration.
