摘要： Technologies for authenticity assurance for I/O data include a computing device with a cryptographic engine and one or more I/O controllers. A metadata producer of the computing device performs an authenticated encryption operation on I/O data to generate encrypted I/O data and an authentication tag. The metadata producer stores the encrypted I/O data in a DMA buffer and the authentication tag in an authentication tag queue. A metadata consumer decrypts the encrypted I/O data from the DMA buffer and determines whether the encrypted I/O data is authentic using the authentication tag from the authentication tag queue. For input, the metadata producer may be embodied as the cryptographic engine and the metadata consumer may be embodied as a trusted software component. For output, the metadata producer may be embodied as the trusted software component and the metadata consumer may be embodied as the cryptographic engine. Other embodiments are described and claimed.

摘要： Technologies for trusted I/O (TIO) include a computing device with a cryptographic engine and one or more I/O controllers. The computing device executes a TIO core service that has a cryptographic engine programming privileged granted by an operating system. The TIO core service receives a request from an application to protect a DMA channel. The TIO core service requests the operating system to protect the DMA channel, and the operating system verifies the cryptographic engine programming privilege of the TIO core service in response. The operating system programs the cryptographic engine to protect the DMA channel in response to verifying the cryptographic engine programming privilege of the TIO core service. If a privileged delegate determines that a user has confirmed termination of protection of the DMA channel, the TIO core service may unprotect the DMA channel. Other embodiments are described and claimed.

摘要： Technologies for secure programming of a cryptographic engine include a computing device with a cryptographic engine and one or more I/O controllers. The computing device establishes one or more trusted execution environments (TEEs). A TEE generates a request to program the cryptographic engine with respect to a DMA channel. The computing device may verify a signed manifest that indicates the TEEs permitted to program DMA channels and, if verified, determine whether the TEE is permitted to program the requested DMA channel. The computing device may record the TEE for a request to protect the DMA channel and may determine whether the programming TEE matches the recorded TEE for a request to unprotect a DMA channel. The computing device may allow the request to unprotect the DMA channel if the programming TEE matches the recorded TEE. Other embodiments are described and claimed.

摘要： The present application is directed to transparent execution of secret content. A device may be capable of downloading content that may include at least one secret portion, wherein any secret portions of the content may be directed to a secure workplace in the device not accessible to device operating system components, applications, users, etc. The device may then present the content in a manner that allows secret portions of the content to be executed without direct access. For example, the device may download content, and a director module in the device may direct any secret portions of the downloaded content to a secure workspace. During execution of the content, any inputs required by the secret portions may be provided to the secure workspace, and any resulting outputs from the secret portions may then be used during content presentation.

摘要： Various embodiments are generally directed to the provision and use of a secure enclave defined within a storage of a computing device by a processor element thereof to store executable instructions of an OTP component implementing logic to generate and use one-time passwords (OTPs) to enable access to services provided by another computing device. An apparatus includes a storage; a first processor element; and first logic to receive a one-time password (OTP) routine, store the OTP routine within a first secure enclave defined by the first processor element within the storage, obtain a measure of the contents of the first secure enclave with the OTP routine stored therein, transmit the first measure to a computing device, and receive an OTP seed. Other embodiments are described and claimed.

摘要： One or more machine readable storage media, an apparatus, and a method. The apparatus provides a mechanism to implement a trusted telemetry governor (TTG) inside a trusted execution environment. The TTG is to determine a security policy to be applied to telemetry data corresponding to component of a computing infrastructure, receive the telemetry data in encrypted format and, based on the security policy: process the telemetry data including at least one of generating transformed telemetry data or analyzing the telemetry data to generate a report therefrom, and generating telemetry information from the telemetry data. The telemetry information includes at least one of processed telemetry data, a report, or a recommendation based on an analysis of the telemetry data. The TTG is to send the telemetry information outside of the trusted execution environment to a consumer of the telemetry data.
