Abstract
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.
