  • Fast processing and encryption method and system for compressed video
    Patent number: 9992535
    Abstract: An encryption method for compressed video is provided. The encryption method includes the steps of confirming a partial bit stream included in a compressed video, and selectively using a lookup table—the lookup table storing encryption information, which is needed for each encryption of a plurality of bit streams, at addresses of patterns respective to the plurality of bit streams—based on a result of the confirmation and encrypting the partial bit stream.
