Abstract
In this paper, we propose a method of conditional access control for encrypted SVC(scalable video coding) bitstream. The main purpose of the proposition is to provide a SVC suitable encryption algorithm and a efficient method for conditional access control using encrypted SVC bitstream. We analyzed requirements for conditional access control of a SVC bitstream. And based on the analysis, we proposed encryption algorithm suitable for SVC bitstream and a method of conditional access control of the encryped bitstream. The proposed conditional access control for encrypted SVC bitstream is performed by bitsream extraction and selective decryption. We verified the usefulness of the proposed method through experiments.
