Broadcast encryption schemes are suitable for one-way content distribution and protection applications.However, most of the related papers are from the theoretical point of view, and there is something useful for implementation being overlooked. In this paper, we introduce the pay-TV system as a concrete implementation of broadcast encryption schemes, and simulate the transmission performance of four highly efficient broadcast encryption schemes. Based on these quantitative results, we analysis performance in respective environments and some suggestions are given based on implementation consideration for further research on this subject.
