Patent number: 11809545Abstract: Data integrity logic is executable by a processor to generate a data integrity code using a hardware-based secret. A container manager, executable by the processor, creates a secured container including report generation logic that determines measurements of the secured container, generates a report according to a defined report format, and sends a quote request including the report. The defined report format includes a field to include the measurements and a field to include the data integrity code, and the report format is compatible for consumption by any one of a plurality of different quote creator types.Type: GrantFiled: July 1, 2022Date of Patent: November 7, 2023Assignee: Intel Corporation, Inc.Inventors: Vincent R. Scarlata, Carlos V. Rozas, Baiju Patel, Barry E. Huntley, Ravi L. Sahita, Hormuzd M. Khosravi

Patent number: 11782849Abstract: A processor includes a decode unit to decode an instruction that is to indicate a page of a protected container memory, and a storage location outside of the protected container memory. An execution unit, in response to the instruction, is to ensure that there are no writable references to the page of the protected container memory while it has a write protected state. The execution unit is to encrypt a copy of the page of the protected container memory. The execution unit is to store the encrypted copy of the page to the storage location outside of the protected container memory, after it has been ensured that there are no writable references. The execution unit is to leave the page of the protected container memory in the write protected state, which is also valid and readable, after the encrypted copy has been stored to the storage location.Type: GrantFiled: July 3, 2021Date of Patent: October 10, 2023Assignee: Intel CorporationInventors: Carlos V. Rozas, Mona Vij, Rebekah M. Leslie-Hurd, Krystof C. Zmudzinski, Somnath Chakrabarti, Francis X. Mckeen, Vincent R. Scarlata, Simon P. Johnson, Ilya Alexandrovich, Gilbert Neiger, Vedvyas Shanbhogue, Ittai Anati

Patent number: 11741230Abstract: Technologies for trusted I/O attestation and verification include a computing device with a cryptographic engine and one or more I/O controllers. The computing device collects hardware attestation information associated with statically attached hardware I/O components that are associated with a trusted I/O usage protected by the cryptographic engine. The computing device verifies the hardware attestation information and securely enumerates one or more dynamically attached hardware components in response to verification. The computing device collects software attestation information for trusted software components loaded during secure enumeration. The computing device verifies the software attestation information. The computing device may collect firmware attestation information for firmware loaded in the I/O controllers and verify the firmware attestation information.Type: GrantFiled: October 22, 2021Date of Patent: August 29, 2023Assignee: INTEL CORPORATIONInventors: Pradeep M. Pappachan, Reshma Lal, Bin Xing, Siddhartha Chhabra, Vincent R. Scarlata, Steven B. McGowan

Publication number: 20230266888Abstract: An integrated circuit includes protected container access control logic to perform a set of access control checks and to determine whether to allow a device protected container module (DPCM) and an input and/or output (I/O) device to communicate securely through one of direct memory access (DMA) and memory-mapped input/output (MMIO). The DPCM and the I/O device are allowed to communicate securely if it is determined that at least the DPCM and the I/O device are mapped to one another, an access address associated with the communication resolves into a protected container memory, and a page of the protected container memory into which the access address resolves allows for the aforementioned one of DMA and MMIO. In some cases, a Security Attributes of Initiator (SAI) or security identifier may be used to obtain a DPCM identifier or attest that access is from a DPCM mapped to the I/O device.Type: ApplicationFiled: December 16, 2022Publication date: August 24, 2023Inventors: Ilya Alexandrovich, Vladimir Beker, Gideon Gerzon, Vincent R.
