Patent number: 10863138Abstract: 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.Type: GrantFiled: May 31, 2016Date of Patent: December 8, 2020Assignee: Intel CorporationInventors: Vidhya Krishnan, Balaji Vembu, Sandeep S.

Patent number: 10552168Abstract: A method dynamically reconfigures a system on a chip (SOC) comprising multiple semiconductor intellectual property (IP) blocks. The method comprises, when booting a data processing system (DPS) comprising the SOC, automatically allocating different IP blocks to multiple different microsystems within the DPS, based on a static partitioning policy (SPP). The method also comprises, after booting the DPS, determining that reallocation of at least one of the IP blocks is desired, based on (a) monitored conditions of at least one of the microsystems and (b) a dynamic partitioning policy (DPP). The method also comprises, in response to determining that reallocation of at least one of the IP blocks is desired, automatically reallocating at least one of the IP blocks from one of the microsystems to another of the microsystems without resetting at least one of the microsystems. Other embodiments are described and claimed.Type: GrantFiled: May 25, 2017Date of Patent: February 4, 2020Assignee: Intel CorporationInventors: Barry E. Huntley, Ned M.

Patent number: 8831213Abstract: A processing system to serve as a source device for protected digital content comprises a processor and control logic. When used by the processor, the control logic causes the processing system to receive a digital certificate from a presentation device. The processing system then uses public key infrastructure (PKI) to determine whether the presentation device has been authorized by a certificate authority (CA) to receive protected content. The processing system may also generate a session key and use the session key to encrypt data. The processing system may transmit the encrypted data to the presentation device only if the presentation device has been authorized by the CA to receive protected content. Presentation devices and repeaters may perform corresponding operations, thereby allowing content to be transmitted and presented in a protected manner. Other embodiments are described and claimed.Type: GrantFiled: February 27, 2012Date of Patent: September 9, 2014Assignee: Intel CorporationInventors: Priyadarsini Devanand, Gary L. Graunke

Patent number: 8155321Abstract: A processing system to serve as a source device for protected digital content comprises a processor and control logic. The processing system may generate and save a first master key, and may transmit that key to a first receiving device for use during a first session. During a second session, the processing system may obtain an identifier for a candidate receiving device. The processing system may use the identifier to determine whether the processing system contains a master key for the candidate receiving device. If the processing system such a master key, the processing system may send verification data concerning that key to the candidate receiving device, and may use that key to encrypt a session key for the second session. If not, a second master key may be generated and transmitted to the candidate receiving device for use during the second session. Other embodiments are described and claimed.Type: GrantFiled: June 24, 2008Date of Patent: April 10, 2012Assignee: Intel CorporationInventors: Priyadarsini Devanand, Gary L. Graunke
