Abstract

See full text

Apparatuses, methods and storage medium associated with single pass parallel encryption are disclosed herein. In embodiments, an apparatus for computing may comprise an encryption engine to encrypt a video stream. The encryption engine may comprise a plurality of encryption pipelines to respectively encrypt a plurality of video sub-streams partitioned from the video stream in parallel in a single pass as the video sub-streams are being generated. The plurality of encryption pipelines may use a corresponding plurality of multi-part encryption counters to encrypt the corresponding video sub-streams as the video sub-streams are being generated. Each of the multi-part encryption counters used by one of the encryption pipelines may comprise a sub-portion that remains constant while encoding the corresponding video sub-stream, but the sub-key is unique for the one encryption pipeline, and differs from corresponding sub-portions of the multi-part encryption counters used by the other encryption pipelines. Other embodiments may be disclosed or claimed.
