Abstract

Broadcast encryption schemes are suitable for one-way content distribution and protection applications. In this paper, we give a concrete implementation framework for how to introduce BE schemes into Conditional Access Systems(CAS). And then we compare the transmission performance of four highly efficient broadcast encryption schemes with traditional CAS system. Based on these experimental results and some reference experiences, we analysis the advantages and challenges of broadcast encryption scheme implementation. At last, some research suggestions are given for further research on this subject.
