For original paper see ibid., vol. 7, no. 2, p. 330-8 (2005). To protect multimedia data in audio and video streaming applications from unauthorized access by intruders, Yeung et al. recently proposed a multikey multimedia proxy with enhanced security features based on asymmetric reversible parametric sequences (ARPS) and the RSA technique. The authors claimed that their scheme provided a number of security features, including data confidentiality against member collusion. However, the security of their scheme is not as robust as they claim. In this paper, it is shown that the YLY-scheme remains vulnerable to collusion attacks
