A real-time ciphering transcoder for H.264 and HEVC streams
Abstract
This paper presents a novel approach for real-time encryption of both H.264 and HEVC encoded streams. Our method relies on structure-preserving Selective Encryption (SE) managed by a symmetric ciphering/deciphering transcoder. Developped as an autonomous tool, it can be implemented within any existing software and hardware architecture and requires very low computational cost. The Advanced Encryption Standard (AES) manages the encryption step to guarantee the protection of encrypted streams. Our method preserves source format and overall bitrate, which ensures undetectable ciphering and suitability for streaming over heterogeneous networks. Experimental evaluation of our proposed transcoder is provided in this paper and a demonstrator of an implementation on a mobile device will support these theoretical results.

If SE is not format compatible, the transcoder has to be modified.
“If the form of SE is not format compatible, as occurred in [9] for the I-frame encryption option, then the transcoder has to be modified.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
