- Abstract
- We propose a protection scheme for MPEG-2 streaming media. To protect MPEG-2 media more effectively and securely, an encryption process should be considered on encoding phase of uncompressed stream and also a streaming server should be designed to support the protection scheme. However this way cannot support existing streaming systems and requires pre-processing such as demultiplexing and decoding. Our approach is to design a protection scheme independent to the streaming server. So, we propose an encryption method which can be applied to compressed MPEG-2 transport stream (TS). Proposed scheme can protect attacks over networks since streaming server streams pre-encrypted content and enables the client to decrypt the streamed data and playback in real time. Even though streamed content is stored in local system users who do not have available rights cannot use the encrypted content.
