Abstract
Mobile pay-TV systems represent an application of important electronic commerce, providing mobile users with the multimedia services. In 2016, Farash and Attari employed the elliptic curves and bilinear pairing technologies to design a one-to-many authentication scheme for mobile pay-TV systems. They claimed that their scheme provides a high level of efficiency and can resist most attacks on mobile pay-TV systems. In this paper, we point out their scheme cannot achieve the fundamental requirement of authentication that is, the mutual authentication. In addition, their scheme still suffers from three security weaknesses.
