WebOct 6, 2024 · We demonstrate how a targeted bitstream modification can seriously weaken cryptographic algorithms, which we show with the examples of AES and 3-DES. WebSystems and methods are described for simplifying the sub-bitstream extraction and the rewriting process. In an exemplary method, a video is encoded as a multi-layer scalable bitstream including at least a base layer and a first non-base layer. The bitstream is subject to the constraint that the image slice segments in the first non-base layer each …
