암호화된 SVC 비트스트림에서 조건적 접근제어 방법

국문 초록 (Abstract)

본 논문에서는 암호화된 SVC (Scalable video coding) 비트스트림을 이용한 조건적 접근제어 방법을 제안한다. 제안한 방법은 새로운 비디오 코딩 기법인 SVC에 적합한 암호화와 암호화된 SVC 비트스트림에서 비트스트림 추출 (Extraction) 후 복호화를 통해 효과적인 조건적 접근제어(Conditional Access Control) 방법을 제공하는데 그 목적이 있다. 제안하는 SVC 조건적 접근제어는 SVC 비트스트림의 암호화에 대한 요구사항을 분석하여 SVC 코딩기법에 적합하게 암호화를 시행하고 암호화된 SVC 비트스트림의 적응변환 수행 시 비트스트림 추출과 선택적 복호화를 통해 수행 된다. 본 논문은 SVC 비트스트림에 대해 암호화를 시행한 후 다양한 비디오로 접근을 시도하는 실험을 통하여 제안한 방법의 유효성을 검증하였다.

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.
